Description

  The present invention relates to a tinnitus reduction information setting device for information, a tinnitus reduction device, and a tinnitus reduction information setting method for reducing human tinnitus.

Conventionally, for example, Patent Document 1 below discloses a tinnitus rehabilitation device. This tinnitus rehabilitation device uses a software that corresponds to a predetermined masking algorithm that is tailored to the hearing loss characteristics of the patient to change the intensity of the acoustic signal at the selected frequency, and the intermittent tinnitus of the patient. By performing appropriate masking, the tinnitus is substantially reduced during the peak of the acoustic signal.
JP 2005-118565 A

  However, according to the above tinnitus rehabilitation device, even if the patient's tinnitus can be substantially weakened, the patient's tinnitus is only intermittently masked. Therefore, the patient's tinnitus cannot be continuously masked. With this, the patient's tinnitus cannot be reduced well. This is significant when the patient's tinnitus includes multiple frequency components.

  Therefore, in order to deal with the above-described problem, the present invention effectively utilizes the main frequency component of the tinnitus sound even if the patient's tinnitus sound includes a plurality of frequency components, and the patient's tinnitus sound is good. An object of the present invention is to provide a tinnitus reduction information setting device for setting information for reducing the tinnitus, a tinnitus reduction device using the tinnitus reduction information setting device, and a tinnitus reduction information setting method.

  In solving the above-mentioned problems, the present inventors have developed tinnitus by adjusting the phase of a pure tone having the main frequency component of the tinnitus and loading it on the patient even if the patient's tinnitus includes a plurality of frequency components. Based on the idea that sound could be reduced, we tried and evaluated a number of subjects on the reduction of tinnitus. As a result, it was found that the above idea was correct.

Under such a premise, the tinnitus reduction information setting device according to the present invention is a pure tone data generating means (10) for generating main frequency components included in a patient's tinnitus as pure tone data. 20)
Phase adjustment data creating means (111, 120, 121, 122) for creating phase adjustment data having a phase difference corresponding to the number of first operations (P, Q) of the operating means for the pure tone data;

Phase adjustment sound signal output means (126, 40, 41) for outputting the phase adjustment sound signal to the auditory part of the patient;
When the patient determines that the tinnitus sound has been reduced to such an extent that the tinnitus sound has disappeared based on the phase adjustment sound signal from the phase adjustment sound signal output means, the operation means performs a second operation indicating that effect, thereby causing the tinnitus There is provided tinnitus reduction information setting means (130, 131) for setting the phase difference of the phase adjustment data when the sound is reduced to the extent that it feels disappeared as tinnitus reduction information for the patient.

  As described above, when the pure tone data is generated with the main frequency component included in the tinnitus of the patient, the phase adjustment data corresponds to the phase difference corresponding to the number of first operations of the operating means with respect to the pure tone data. The phase adjustment sound signal is generated so as to have the phase difference with respect to the phase adjustment data and is output to the patient's auditory part.

  When the patient determines that the tinnitus sound has been reduced to the extent that the tinnitus sound has disappeared based on the phase adjustment sound signal, the second operation is performed by the operating means, thereby reducing the tinnitus sound to the extent that it is felt to have disappeared. The phase difference of the phase adjustment data at the time is set as tinnitus reduction information for the patient.

  Therefore, according to the tinnitus reduction information set in this way, even if the patient's tinnitus sound includes a plurality of frequency components, the phase adjustment sound signal is reduced when the above-described tinnitus sound is reduced to such an extent that it feels like it has disappeared. It can be easily set as a sound signal.

  The phase adjustment sound signal is generated by adjusting the phase of pure sound data as described above. Therefore, if the main frequency component is a component such as a sine wave component or a cosine wave component having a single main frequency, the phase adjustment sound signal is a component such as the sine wave component or the cosine wave component. Are different in phase, and become a continuous signal corresponding to the sine wave component or cosine wave component corresponding to the tinnitus sound. This means that the tinnitus reduction sound signal set as described above also becomes a continuous signal.

Hereinafter, each embodiment of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 shows a first embodiment of a tinnitus reduction device to which the present invention is applied. The tinnitus reduction device is applied to a patient who is aware of tinnitus. The tinnitus reduction device includes a signal generator 10, an analog-digital converter 20 (hereinafter referred to as an A-D converter 20), and a notebook personal computer. A computer 30 (hereinafter referred to as a personal computer 30) is provided.

  The signal generator 10 receives an approximate sound that most closely approximates the tinnitus sound unique to the patient, performs frequency analysis of the approximate sound, searches for a main frequency component of the approximate sound, and uses the main frequency component as a pure tone signal. Occurs as. However, the main frequency component described above is a frequency component that identifies the tinnitus sound of the patient, that is, a sine wave component of a single main frequency that the patient recognizes as the closest to his / her tinnitus sound among the approximate sounds. This is a sine wave component synchronized with the tinnitus sound. In the first embodiment, as the signal generator 10, a GAA-810 type audio generator manufactured by GW Instruments Inc. of the United States is employed.

  The AD converter 20 digitally converts the pure tone signal from the signal generator 10 and outputs it to the personal computer 30 as pure tone data.

  The personal computer 30 includes a keyboard 30a, a computer main body 30b, a display drive circuit 30c, and a liquid crystal display 30d. The keyboard 30a outputs an operation input to the computer main body 30b by the key operation.

  The computer main body 30b executes a computer program in accordance with the flowcharts shown in FIGS. 2 and 3, and the computer main body 30b performs an operation input from the keyboard 30a and an output of the A / D converter 20 during the execution. Based on the above, various arithmetic processes required for the output to the bone conduction terminal member 40 for hearing test are performed.

  In the first embodiment, the computer program is stored in a readable manner in the ROM of the computer main body 30b. Further, adjustment phase angle-operation frequency data (see FIG. 4) and identification color-adjustment phase difference data (see FIG. 5) are stored in a readable manner in the ROM of the computer main body 30b.

  The adjustment phase angle-operation frequency data is used to adjust the phase of pure tone data (described later) by operating the advance key or the delay key, and the adjustment phase angle-operation frequency data corresponds to the pure tone data. Correspondence relationship between the adjustment phase angle Φ (i) (i = 0, 1, 2,..., M, m + 1,..., 2m) and the advance key operation frequency data P or the delay key operation frequency Q. Represents. In Φ (i), m is a positive integer.

  Here, the advance key is an operation key that is operated when the phase of the pure tone data is advanced, and corresponds to an operation key marked with “←” on the keyboard 30a. The delay key is an operation key that is operated when the phase of the pure tone data is delayed, and corresponds to an operation key marked with “→” on the keyboard 30a.

  The adjustment phase angle per operation of the advance key or the delay key is a predetermined phase angle Φo (for example, 5 °). The adjustment phase angle with respect to the operation of the advance key is an advance phase angle, while the adjustment phase angle with respect to the operation of the delay key is a delay phase angle. Therefore, the adjustment phase angle Φ (i) changes to the + side or the − side according to the number of operations N on the advance side or the delay side.

  As shown in FIG. 5, the identification color-adjustment phase difference data represents a correspondence relationship between the identification color data and the adjustment phase difference ΔΦ. The adjustment phase difference ΔΦ represents the phase angle of the pure tone data and the number of operations. This represents a difference between the phase of the pure tone data and the adjustment phase angle according to the change of the data P (or Q). The identification color data is changed from the first color to the m-th color (for example, the 36th color) in accordance with the change of the adjustment phase difference ΔΦ = ± Φ (0) = 0 ° to ΔΦ = ± mΦo = ± 180 °. ΔΦ = ± changes in steps for each predetermined phase angle Φo (for example, 5 °), and the m-th color with a change of the adjustment phase difference ΔΦ = ± mΦo = ± 180 ° to ΔΦ = ± 2 mΦo = ± 360 ° From (for example, the 36th color) to the second m color (for example, the 72nd color), it changes stepwise for every ΔΦ = ± predetermined phase angle Φo (for example, 5 °).

  In the first embodiment, the identification color data is the first identification color or the second m identification color (for example, the 72nd identification color) when ΔΦ = 0 ° or ± 360 °, and ΔΦ = ± 180 °. The mth identification color (for example, the 36th identification color). Here, the first identification color or the second m identification color (for example, the 72nd identification color) is red, and the mth identification color (for example, the 36th identification color) is blue. The identification color data changes from red to blue in a stepwise manner from the first identification color to the mth identification color, and sequentially from blue to red from the mth identification color to the second m identification color. It is set so that it may change so that it may approach. The identification color data undergoes a color change symmetrically toward the phase advance side and the phase delay side with reference to 0 °.

  The display 30d is driven by the display drive circuit 30c under the control of the computer main body 30b to display display data.

  The bone conduction terminal member 40 is attached to the posterior ear bone part of the patient's head M. The bone conduction terminal member 40 receives an output from the computer main body 30b via the cable 41 at the vibration part. Vibrate and input this vibration into the posterior ear bone of the head M. The vibration input to the patient's posterior ossicle reaches the patient's cochlea without attenuation or time delay, so that the patient can quickly output from the computer main body 30b by his / her hearing. recognize.

  In the first embodiment configured as described above, when the personal computer 30 is in an operating state, the computer main body 30b starts executing the computer program according to the flowcharts of FIGS. Then, in step 100, each operation count data is cleared as P = 0 and Q = 0. The operation count data P is data representing the number of operations of the advance key, while the operation count data Q is data representing the number of operations of the delay key.

  Next, at step 110, it is determined whether or not pure tone data is input. At this stage, since the pure tone data is not generated from the AD converter 20, the determination of NO is repeated in step 110.

  Here, the pure tone data is generated from the AD converter 20 as follows. Prior to the generation of the pure tone data, the approximate sound of the patient's tinnitus to be input to the signal generator 10 as described above is specified as follows.

  First, the tinnitus of the patient is examined using a tinnitus testing device (not shown) under an inquiry to the patient. Here, the tinnitus inspection device generates, as the approximate sound, a sound that is the closest to the tinnitus sound of the patient and is synchronized with the tinnitus sound.

  When the approximate sound of the tinnitus sound of the patient generated in this way is input from the tinnitus inspection apparatus to the signal generator 10, the signal generator 10 analyzes the frequency of the approximate sound. Then, when the main frequency component of the approximate sound is searched as a component synchronized with the approximate sound by the signal generator 10 based on the frequency analysis, the main frequency component is output from the signal generator 10 as a pure sound signal, It is digitally converted by the AD converter 20 and generated as pure tone data.

  When pure tone data is generated from the AD converter 20 in this way, the pure tone data is input to the computer main body 30b. Then, it determines with YES in step 110. FIG.

  In step 111, pure tone data is set. Accordingly, pure tone data input from the A-D converter 20 is stored in the RAM in the computer main body 30b. This means the set of pure tone data in the computer main body 30b.

  Thereafter, in step 112, the identification color data is read out. At this stage, since the operation count data P = Q = 0 and the adjustment phase difference ΔΦ = 0 °, in Step 112, the first identification color (red) is used as the identification color-adjustment color as the identification color data. It is read from the ROM of the computer main body 30b based on the phase difference data.

  When the processing in step 112 is completed in this way, in the next step 113, composite display data creation / output processing is performed. Accordingly, the pure tone data in step 111 is superimposed on the orthogonal coordinate plane a1 (see FIG. 6), and the identification color data representing the first identification color (red) in step 112 is superimposed on the square area c to display data. After that, the combined display data is converted to analog and output to the display drive circuit 30c.

  For this reason, the display 30d is driven by the display drive circuit 30c based on the composite display data from the computer main body 30b. On the display screen, as shown in FIG. And identification color data representing the first identification color (red) (see the shaded area in FIG. 6) is displayed together with the square area c. As a result, the patient visually recognizes that the pure tone specifying his / her tinnitus sound is specified by the sine wave a, and indicates that the phase of the pure tone data is not adjusted in red in the square region c. You can see it. The sine wave a is a sine wave that becomes zero level when the phase angle = 0 °, and becomes zero level when the phase angle after one cycle = 360 °.

  When the processing in step 113 is completed as described above, in the next step 120, it is determined whether or not the advance key or the delay key is operated. At this stage, since the advance key or the delay key has not been operated yet, the determination of NO in step 120 is repeated.

  Here, when the patient operates the advance key once, the determination in step 120 becomes YES, and in the next step 121, the operation number of the advance key is added and updated as operation number data P = P + 1 = 1. .

  Thereafter, in step 122, phase adjustment data generation processing based on pure tone data is performed. In this creation process, the adjustment phase angle Φ (i) is determined from the adjustment phase angle−operation frequency data (see FIG. 4) based on the operation frequency data P = 1, + Φ (1) = + Φo (for example, + 5 °). Is read as Next, since the adjustment phase angle Φ (i) = + Φ (1) = + Φo is the advance phase angle corresponding to the operation of the advance key, the pure tone data is obtained at the phase angle based on the advance phase angle + Φo. , + Φo, and is created as phase adjustment data. This means that the phase adjustment data is created by adjusting the phase so that the pure tone data advances by the adjustment phase difference ΔΦ = + Φo.

  When the processing in step 122 is completed in this manner, in the next step 123, identification color data reading processing is performed. In this reading process, since the operation frequency data P = 1 and the adjustment phase difference ΔΦ = + Φo, in step 123, the second identification color is identified as identification color data based on the identification color-adjustment phase difference data. It is read from the ROM of the main body 30b.

  When the processing in step 123 ends in this way, in the next step 124, a phase adjustment sound signal generation process is performed. In this generation process, based on the phase adjustment data in step 122, a phase adjustment sound signal (having a phase of adjustment phase difference ΔΦ = + Φo) corresponding to the phase adjustment data is generated.

  Thereafter, in step 125, a composite display data creation / output process is performed. In this creation output process, the pure tone data in step 111 is superimposed on the orthogonal coordinate plane a1, the phase adjustment data in step 122 is superimposed on the orthogonal coordinate plane b1 (see FIG. 6), and the identification color data in step 123 is the square area c. Are combined as display data, and the combined display data is converted to analog and output to the display drive circuit 30c.

  Therefore, the display 30d is driven by the display driving circuit 30c based on the composite display data from the computer main body 30b, and as shown in FIG. 6, the pure tone data is displayed with the sine wave a together with the orthogonal coordinate plane a1, and the phase The adjustment data is displayed together with the orthogonal coordinate plane b1 as a sine wave b (see the broken line in FIG. 6), and the identification color data representing the second identification color is displayed together with the square area c. Thereby, it can be visually recognized by the patient with the two identification color display in the square area c that the sine wave b corresponding to the phase adjustment data is advanced by the phase difference + Φo with respect to the sine wave a.

  In addition, after the processing of step 125, in step 126, the phase adjustment sound signal is output. In this output process, the phase adjustment sound signal (having the phase of the adjustment phase difference ΔΦ = + Φo) generated in step 124 is converted into an analog signal and output to the bone conduction terminal member 40 via the cable 41. Then, the bone conduction terminal member 40 vibrates in response to the phase adjustment sound signal at the vibration part, and inputs this vibration to the posterior bone part of the head M of the patient. For this reason, the patient quickly recognizes the output from the computer main body 30b as a phase adjustment sound by his / her hearing. Thereby, the state of the tinnitus of the patient can be recognized by the patient with his / her hearing.

  After step 126, it is determined in step 130 whether the patient's tinnitus has disappeared. At the present stage, when the patient determines that the tinnitus sound has not disappeared, if a key with “N” on the keyboard 30a (hereinafter referred to as N key) is operated by the patient, NO is determined in step 130. Is done.

  Therefore, if the determination in step 130 is NO, at the present stage, P <2m and Q <2m. Therefore, NO is determined in step 140. After the determination of NO in step 140, the processing from step 120 to step 130 is repeated under the addition update of the operation frequency data P for each advance key operation. After the latest steps 122 to 126, when the patient determines that the tinnitus sound has disappeared, the key (hereinafter referred to as the Y key) on the keyboard 30a is operated by the patient. In step 130, it is determined YES.

  Accordingly, in step 131, phase difference determination processing for pure tone data of phase adjustment data is performed. In this phase difference determination process, the phase difference between the latest phase adjustment data in step 122 and the pure tone data in step 111 is determined. This means that the phase of the reduction sound of the patient's tinnitus is set by the phase difference.

  The phase difference determined as described above corresponds to + mΦo = + 180 ° because the tinnitus sound has disappeared. In other words, the latest adjusted phase data is a sine wave bo (indicated by a solid line in FIG. 6) having a reverse phase (inverted phase) with respect to the pure tone data, in other words, an inverted phase difference of 180 ° with respect to the pure tone data. Specified by sine wave).

  Thus, after the process of step 131, in step 132, the process of outputting the tinnitus reduction sound signal having the phase having the determined phase difference (+ 180 °) is performed. Accordingly, a tinnitus reduction sound signal having a lead phase of 180 ° with respect to the sine wave a of the pure tone data is generated based on the latest adjusted phase data and output to the bone conduction terminal member 40 via the analog converted cable 41. Is done.

  Then, the bone conduction terminal member 40 vibrates in response to the above-described tinnitus reduction sound signal at the vibrating portion, and inputs this vibration to the posterior ear bone portion of the head M of the patient. Here, the tinnitus reduction sound signal has an inverted phase with respect to the phase of the sine wave a of the pure tone data. The approximate sound of the tinnitus sound of the patient is recognized by the patient as approximating the tinnitus sound, and the pure sound corresponds to the main frequency component of the approximate sound as described above.

  Therefore, the pure tone, and thus the approximate sound of the patient, in other words, the tinnitus sound of the patient is satisfactorily canceled by the vibration of the bone conduction terminal member 40 based on the sound reduction sound signal. As a result, it can be recognized by the patient that the tinnitus has disappeared. This means that the tinnitus sound of the patient is reduced (specifically extinguished) by the tinnitus reduction device.

  As described above, according to the first embodiment, even if the tinnitus sound of the patient includes a plurality of frequency components, if the approximate sound of the tinnitus sound can be specified, the tinnitus mitigation apparatus can reduce the approximate sound. The pure tone data corresponding to the main frequency component, that is, the sine wave component of a single main frequency and synchronized with the tinnitus sound is converted into the adjustment phase angle-operation frequency data and the identification color-adjustment. By adjusting the phase based on the phase difference data and displaying the identification color, the tinnitus reduction sound signal suitable for reducing the patient's tinnitus sound, specifically the tinnitus reduction sound signal suitable for eliminating the patient's tinnitus sound. Can be set easily.

  The phase adjustment sound signal is generated by adjusting the phase of pure sound data as described above. Therefore, since the main frequency component is a sine wave component having a single main frequency, the phase-adjusted sound signal corresponds to the tinnitus sound only by making the phase different from that of the sine wave component. It becomes a continuous signal corresponding to the sine wave component. This means that the tinnitus reduction sound signal set as described above also becomes a continuous signal. Therefore, by using such a tinnitus reduction sound signal, the tinnitus sound of the patient can be continuously and satisfactorily eliminated.

  Further, when the identification color display on the display 30d changes from red to blue, the patient determines the phase difference of the phase adjustment data suitable for the reduction (specifically, disappearance) of his / her tinnitus sound with respect to the pure tone data. Since it is good, the determination of this phase difference is easy.

  In addition, as described above, the main frequency component is searched for from the approximate sound that is the closest approximation to the patient's tinnitus obtained from the tinnitus inspection device and is synchronized with the tinnitus, thus specifying the pure tone data. The main frequency component appropriately corresponds to the tinnitus of the patient. Therefore, the tinnitus reduction sound signal suitable for continuously reducing (specifically, eliminating) the tinnitus sound of the patient can be set to appropriately correspond to the tinnitus sound. Thereby, if such a tinnitus mitigation sound signal is utilized, a patient's tinnitus sound can be turned off still more favorably.

  In the first embodiment, as described above, both the input of the tinnitus reduction sound signal from the bone-conducting terminal member 40 to the posterior bone part of the head M of the patient and the display of the adjustment phase data on the display 30d are provided. Since the patient can recognize that the tinnitus has disappeared, the accuracy of this recognition is further increased.

  Further, according to the tinnitus rehabilitation apparatus described in the background art above, the predetermined mask algorithm is finished according to the hearing loss characteristic of the patient so as to change the intensity of the acoustic signal at the selected frequency. Therefore, the predetermined mask algorithm, in other words, the software configuration corresponding to the algorithm must be complicated. This is particularly noticeable when the patient's tinnitus includes multiple frequency components.

  However, in the first embodiment, simply using the pure tone data set as described above, and adjusting the phase difference with respect to the pure tone data by the key operation of the keyboard 30a, as described above, the tinnitus of the patient. It is possible to easily determine the phase adjustment data that can mute the sound. Therefore, a complicated software configuration such as the above-described tinnitus rehabilitation apparatus is unnecessary.

  Further, in the second embodiment, pure tone data is shown in order to show an example in which the operation of the advance key of the keyboard 30a is started from the phase angle 0 ° of the sine wave a (see FIG. 6) showing the pure tone data. Although an example in which the sine wave a rises from a phase angle of 0 ° is shown in FIG. 6, the operation of the advance key of the keyboard 30a is started from any phase angle of the sine wave a as a starting point. May be. For example, if the operation of the advance key of the keyboard 30a is started from the phase angle 45 ° or 90 ° of the sine wave a, the inverted phase difference of the phase adjustment data with respect to the pure tone data is 135 ° or 90 °. Become.

Although the above-described predetermined phase angle Φo is exemplified as 5 °, the smaller the predetermined phase angle Φo is, the higher the determination accuracy in step 130 is. Also, by operating the delay key instead of the operation of the advance key, the same effect as the operation of the advance key can be achieved under the same processing by the computer main body 30b as described above.
(Second Embodiment)
7 and 8 show the main part of the second embodiment of the present invention. The second embodiment has been proposed in order to perform the phase adjustment for the pure tone data described in the first embodiment more quickly. Accordingly, in the second embodiment, the computer main body 30b described in the first embodiment replaces the flowcharts of FIGS. 2 and 3 with the computer program according to the flowcharts shown in FIGS. Has been changed to run. Other configurations are the same as those in the first embodiment.

  In the second embodiment configured as described above, as in the first embodiment, the pure tone data is displayed with the sine wave a along with the orthogonal coordinate plane a1 under the processing of step 100 to step 113, and When the first identification color (red) is displayed together with the square area c, the patient visually recognizes that the pure tone specifying his / her tinnitus sound is specified by the sine wave a, and converts the pure tone data into the square. It can be visually recognized with a red display in the area c.

  After the processing of step 113, in the second embodiment, it is determined in step 120a (see FIG. 7) whether or not the advance key is operated. Here, if the advance key is operated by the patient, the determination in step 120a is YES. Next, in step 120b, it is determined whether or not the first key operation. At the present stage, since the previous advance key operation (the advance key operation in step 120a) is the first key operation, the determination in step 120b is YES. Then, in step 121a, the operation count data P is added and updated as P = P + 1 = 1.

  Thereafter, the processing of step 122 to step 126 (see FIGS. 7, 8, 2, and 3) is performed as in the first embodiment. Accordingly, as in the first embodiment, the pure tone data is displayed with the sine wave a and the orthogonal coordinate plane a1, and the phase adjustment data is displayed with the orthogonal coordinate plane b1 and the sine wave b (see the broken line in FIG. 6). The identification color data that is displayed and represents the second identification color is displayed together with the square area c and is based on the phase adjustment sound signal (having the phase of the adjustment phase difference ΔΦ = + Φo) that is output from the computer main body 30b. Vibration is input to the posterior ossicle of the patient's head M by the bone conduction terminal member 40.

  Thereby, the fact that the sine wave b corresponding to the phase adjustment data is advanced by the phase difference + Φo with respect to the sine wave a can be visually recognized by the patient with the first identification color display in the square region c, and the computer body The phase adjustment sound based on the output from 30b can be recognized by the patient with its hearing. As a result, the state of the tinnitus of the patient can be recognized by the patient with his / her hearing.

  When the processing in steps 122 to 126 is completed as described above, it is determined in the next step 127a (see FIG. 7) whether P = 1 or Q = 1. At this stage, since P = 1, the determination in step 127a is YES.

  Next, in step 130, it is determined whether the tinnitus sound has disappeared. If the patient determines that the tinnitus sound has not disappeared based on the state of the tinnitus sound recognized by the patient as described above, the determination in step 130 is NO in accordance with the operation of the N key on the keyboard 30a. .

  Accordingly, in step 130a, it is determined whether or not the tinnitus is reduced. At this stage, if the tinnitus sound has not disappeared but has been reduced, YES is determined in step 130a in accordance with the operation of the Y key of the keyboard 30a.

  If the determination in step 130a is no, it is determined in step 130b whether or not the tinnitus is enhanced. At this stage, if the tinnitus sound is not enhanced based on the state of the tinnitus sound recognized by the patient as described above, the determination in step 130b is NO in accordance with the operation of the N key of the keyboard 30a.

  Therefore, if the determination in step 130a is YES or NO in step 130b as described above, it is determined in step 140 whether P = 2m or Q = 2m. At the present stage, since P = 1, the determination in step 140 is NO. In step 141, the previous key operation is not a delay key operation, so it is determined NO, and the computer program is Proceed to step 120a.

  Here, when the advance key is operated again, it is determined NO in step 120b because the advance key is not operated after the determination of YES in step 120a. Next, in step 120c, it is determined whether or not the previous key operation is an advance key operation. However, since the previous key operation is the advance key operation as described above, the determination in step 120c is YES, and in step 121a, the operation count data is added and updated as P = P + 1 = 2. .

  Along with this, the processing from step 122 to step 126 is performed based on the operation count data P = 2. Then, as in the first embodiment, the pure tone data is displayed with the sine wave a and the orthogonal coordinate plane a1, and the phase adjustment data is displayed with the orthogonal coordinate plane b1 and the sine wave b (see the broken line in FIG. 6). The identification color data representing the third identification color is displayed together with the square area c, and the phase adjustment sound signal (adjustment phase difference ΔΦ = + Φ (2) = + 2Φo) that is output from the computer main body 30b. ) Is input to the posterior ossicle of the patient's head M by the bone-conducting terminal member 40.

  Thereby, the fact that the sine wave b corresponding to the phase adjustment data is advanced by the phase difference + 2Φo with respect to the sine wave a can be visually recognized by the patient with the second identification color display in the square area c, and the computer body The phase adjustment sound based on the output from 30b can be recognized by the patient with its hearing. As a result, the state of the tinnitus of the patient can be recognized by the patient with his / her hearing.

  When the processing in steps 122 to 126 is completed as described above, NO is determined in the next step 127a based on P = 2. At this stage, if it is determined that the tinnitus has not disappeared based on the state of the tinnitus sound of the patient described above, the determination in step 130d is NO, and the determination in step 140 is NO under P = 2.

  Therefore, it is determined that the tinnitus has disappeared based on the latest state of the above-mentioned patient's tinnitus during the repeated processing of Step 120a to Step 127a under the determination of NO in Step 141 and the addition update of the operation frequency data P. Then, the patient operates the Y key. For this reason, in step 130d, it is determined as YES, and the processes of steps 131 and 132 are performed. Accordingly, as in the first embodiment, the phase difference from the pure tone data of the latest phase adjustment data is determined based on the value of the latest operation frequency data P, and the latest phase adjustment data is also obtained. Based on the tinnitus reduction sound signal, the bone conduction terminal member 40 inputs the back ear bone portion of the head M of the patient. Therefore, it can be recognized by the patient that the tinnitus sound has disappeared as in the first embodiment.

  In addition, when the computer program proceeds to step 130b as described above, the tinnitus sound is enhanced unlike the above, and therefore, when the Y key of the keyboard 30a is operated and YES is determined in step 130b. In step 130c, it is determined whether or not the delay key is operated. In other words, since the tinnitus sound tends to increase, it is determined that the continuation of the advance key operation increases the number of operation of the advance key and takes time for the phase adjustment. For this reason, the delay key is operated. Accordingly, the determination in step 130c is YES, and in step 133, the operation count data is cleared to P = 0.

  Next, in step 120c, it is determined whether or not the previous key operation is an advance key operation. Here, since the determination in the previous step 130c is based on the operation of the delay key, the determination in step 120c is determined as NO. Then, in step 121b, the operation count data Q that has been cleared in step 100 is added and updated as Q = Q + 1 = 1. Accordingly, the processing from step 122 to step 126 is performed under Q = 1. That is, in the phase adjustment data creation process based on the pure tone data in step 122, the adjustment phase angle Φ (i) is obtained from the adjustment phase angle-operation frequency data (see FIG. 4) based on the operation frequency data Q = 1. Read out as −Φ (1) = − Φo (for example, −5 °). Next, since the adjustment phase angle Φ (i) = − Φ (1) = − Φo is a delay phase angle corresponding to the operation of the delay key, the pure tone data is obtained based on the delay phase angle −Φo. The phase angle is advanced by −Φo and is created as phase adjustment data. This means that the phase adjustment data is created by adjusting the phase of the pure tone data so as to be delayed by the adjustment phase difference ΔΦ = −Φo.

  When the process in step 122 is completed in this way, in the identification color data reading process in the next step 123, since the operation frequency data Q = 1 and the adjustment phase difference ΔΦ = −Φo, the second identification color is The identification color data is read from the ROM of the computer main body 30b based on the identification color-adjusted phase difference data.

  Then, in the phase adjustment sound signal generation process in the next step 124, a phase adjustment sound signal (having a phase of adjustment phase difference ΔΦ = −Φo) corresponding to the phase adjustment data is generated based on the phase adjustment data in step 122. Is done. Thereafter, in the composite display data creation and output process in step 125, the pure tone data in step 111 is superimposed on the orthogonal coordinate plane a1, and the phase adjustment data in step 122 (corresponding to ΔΦ = −Φo) is applied to the orthogonal coordinate plane b1. The identification color data (corresponding to the second identification color) in step 123 is superimposed on the square area c and synthesized as display data, and then the synthesized display data is converted to analog and output to the display drive circuit 30c. The

  Therefore, the display 30d is driven by the display drive circuit 30c based on the composite display data to display the pure tone data with the sine wave a together with the orthogonal coordinate plane a1, and the phase adjustment data with the orthogonal coordinate plane b1 as a sine wave. The identification color data that is displayed and that represents the second identification color is displayed together with the square area c. Thereby, it can be visually recognized by the patient with the two identification color display in the square region c that the sine wave corresponding to the phase adjustment data is delayed by the phase difference −Φo with respect to the sine wave a.

  In addition, after the processing of step 125, in the output processing of the phase adjustment sound signal in step 126, the phase adjustment sound signal generated in step 124 (having the phase of adjustment phase difference ΔΦ = −Φo) is converted into an analog signal, The signal is output to the bone conduction terminal member 40 via the cable 41. For this reason, the patient recognizes the output from the computer main body 30b as a phase adjustment sound in the same manner as described above. Thereby, the state of the tinnitus sound of the patient when the adjustment phase difference ΔΦ = −Φo can be recognized by the patient.

  When the process of step 126 is completed as described above, since Q = 1 at this stage, YES is determined in step 127a. Then, as described above, the determination of both steps 130 and 130a is made in the same manner as the determination of both steps 130 and 130a under P = 1. As described above, the operation of the advance key enhances the patient's tinnitus sound, so the operation is changed to the delay key operation. Therefore, the patient's tinnitus sound tends to decrease even if it does not disappear. To be judged.

  Therefore, even if it is determined NO in step 130 after determination of YES in step 127a, it is determined YES in step 130a. Accordingly, if it is determined NO in step 140 because Q <2m, in the next step 141, it is determined YES because the previous key operation is the operation of the delay key.

  Then, in step 142 (see FIG. 7), it is determined whether or not the delay key is operated. If the delay key is operated again during the determination of NO in step 142, the determination in step 142 is YES, and the operation count data Q is added and updated as Q = Q + 1 = 2 in step 121b. .

  Thereafter, in steps 122 to 126, based on the operation count data Q = 2, phase adjustment data based on pure tone data (corresponding to -Φ (2) =-2Φo) is created, and color identification data is read (second). Corresponding to the identification color), the generation of the phase adjustment sound signal (corresponding to -Φ (2) =-2Φo), the generation output of the composite display data and the output of the phase adjustment sound signal are substantially the same as in the case of the operation frequency data P = 2 In the same way. As a result, the effect on the delay phase adjustment of the pure tone data under the operation count data Q = 2 is obtained in substantially the same manner as the effect on the advance phase adjustment of the pure tone data under the operation count data P = 2. It is done.

  Thereafter, during the repetition of the arithmetic processing through each step 127a, 130d, 140, 141, 142, 121b, 122-126, the patient's tinnitus sound disappears under the addition update of the operation count data Q, and step 130d. If the determination in step YES is YES, the processes of steps 131 and 132 are performed.

  Accordingly, the phase difference between the latest phase adjustment data and the pure tone data is determined based on the latest operation count data Q, and the tinnitus reduction sound signal based on the latest phase adjustment data is supplied to the bone conduction terminal. Input to the posterior ossicle of the patient's head M by the member 40. Therefore, it can be recognized by the patient that the tinnitus sound has disappeared.

  Here, as described above, after the operation of the advance key, if it is determined YES in step 130b based on the enhancement of the tinnitus by the operation of the Y key, the operation of the advance key is not continued as it is. By repeatedly operating the delay key, the processing of steps 131 and 132 can be achieved very quickly as described above during the repetition of the arithmetic processing through steps 120c, 121b, 122 to 126, 127a, and 130d. This means that the output of the tinnitus reduction sound signal required for the reduction (specifically, disappearance) of the tinnitus sound of the patient can be made very quickly. As a result, it can be quickly recognized by the patient that the tinnitus has disappeared. Other operations and effects are the same as those of the first embodiment.
