Description

  The present invention relates to a hearing ability test apparatus that allows a subject to listen to a test sound to test various hearing abilities, and in particular, to listen to various sounds in a daily living environment to cause the sound of the subject to be heard. The present invention relates to a hearing ability inspection device capable of examining the same discrimination ability and tuning ability in high, sound quality, pitch and melody.

As a device for inspecting the hearing ability of a subject, an audiometer is used to check whether or not the subject can hear a test sound having high and low or strong and weak sounds.
This audiometer usually uses a push button type response switch, and a headphone is worn on the subject's ear, and a pure tone (sine wave audio signal) is emitted as a test sound to be heard.
At this time, the auditory ability is inspected by determining whether or not the subject operates the response switch as to whether or not the inspection sound can be heard.
However, this audiometer relies on the subject's switch operation, and the switch operation is sometimes performed even when the inspection sound is not heard, so that the problem of low reliability remains.

Therefore, in order to solve such problems, a test sound of a predetermined level is presented to the inspector, and the hearing is inspected while sequentially increasing and decreasing the level of the test sound based on the response obtained from the subject. An audiometer has been proposed (see, for example, Patent Document 1).
In this case, when there is a test subject's response to the test sound, the test sound is temporarily interrupted, and when the response from the test subject is continued, the hearing test is temporarily stopped and a predetermined notification means is provided. This notifies the examiner and the subject that the response from the subject is wrong.
As a result, the response from the subject can be limited only to the inspection sound, the inspection time can be shortened, and the deterioration of the inspection accuracy can be prevented.

FIG. 3 is a rear perspective view showing a sub mouse of the hearing ability test apparatus, and FIG. 4 is a schematic explanatory diagram showing the sub mouse.
The sub mouse 25 has a back surface formed by a sliding member 26 and a sensor 27 provided therein.
The sliding member 26 is made of a synthetic resin material having flexibility, and the bottom surface 26a is substantially flat, while the inner surface 26b is corrugated. The inner surface 26b is formed as a reflecting surface by attaching a thin plate that reflects light or by applying a light-reflecting paint.
Thus, when a part of the body such as a finger is brought into contact with the bottom surface 26a and slid, the inner surface 26b is displaced and the position and angle of the reflecting surface change.

The sensor 27 includes a plurality of sets of light emitting elements and light receiving elements, and is disposed on a wiring board 25a attached to face the inner surface 26b.
Since each light emitting element and the light receiving element are directed to the reflecting surface of the inner surface 26b, the light emitted from the light emitting element is reflected by the reflecting surface due to the displacement of the reflecting surface accompanying the sliding of the sliding member 26, and the light receiving element. Light is received on the side.
Since this light receiving element converts the reflected light into an electrical signal, a signal corresponding to the intensity change of the reflected light is output from the sensor 27.
The sensor 27 is connected to the transmission unit 29 via the signal conversion unit 28. The signal conversion unit 28 converts an electrical signal into a numerical value, and outputs numerical data corresponding to the level of the input signal to the transmission unit 29. Further, the transmission unit 29 transmits numerical data to the personal computer 2 side.

When the sub mouse 25 configured in this manner is connected to the personal computer 2 and starts to be used, an optical signal is emitted from each light emitting element of the sensor 27 toward the reflecting surface of the inner surface 26b. When the user slides the bottom surface 26a with a finger or the like, the reflected light of the optical signal is received by the light receiving element as the inner surface 26b is displaced.
Accordingly, numerical data indicating the operation amount of the sub mouse 25 is output from the signal conversion unit 28. Therefore, when a person with a physical disability, such as a finger, cannot hold and operate the mouse when using it on a flat desk, the user can slide the finger on the bottom surface 26a with the secondary mouse 25 turned upside down, An input operation can be performed simply by touching and moving a part.
In general, the object on which the sliding member 26a is slid is directly by a finger, but it is possible to use a part of the skin of the body. Even a simple person can perform a hearing ability test without any problem.

Next, various display units for the hearing ability test will be described with reference to FIGS.

To proceed. In principle, both the examinee and the inspector wear headphones 21 and 22.
First, when the inspector starts up the personal computer 2, the control unit 15 displays various icons or a selection list on the screen 13a. When the hearing ability test is selected from the display, the control unit 15 shifts to the examination mode and displays the type of the hearing ability test as shown in FIG.
Here, when the inspector selects the first discrimination discrimination ability test in accordance with the guide characters, as shown in FIG. 20, the inspection items of 1 pitch to 6 melody are displayed.
For example, when the inspector selects one pitch, the pitch discrimination discrimination test is started, and the test-dedicated image 31 for the hearing test is displayed on the screen 13a (see FIG. 5).
Note that, in this hearing ability test, the test-dedicated image 31 is first displayed regardless of which test item is selected, thereby enabling an input operation.

FIG. 21 is a flowchart showing main operations in the hearing ability test mode.
When the control unit 15 shifts to the examination mode, the auditory ability examination is started (step S1), and the examination dedicated image 31 is displayed on the screen 13a (step S2).
Then, parallel processing such as voice data generation / reproduction processing (step S3), mouse control (step S7), voice data processing / display (step S9), and the like is performed.
In the sound data generation / reproduction process in step S3, sound parameters are set according to the contents of commands from the main and sub-mouses 24 and 25 (step S4).
Next, based on the setting contents of the voice parameter, the test voice data is generated and reproduced, and the voice data is output to emit the test sound (step S5).
Thereafter, it is determined whether or not there is a command to end the output of the audio data (step S6), and the processing is continued until the end command is received.

Subsequently, in the mouse control in step S7, information of the main and sub-mouses 24 and 25 inputted in real time is processed (step S8), and each part is controlled based on the contents of the command.
Further, in the audio data processing / display in step S9, the inspection content is displayed on the inspection-dedicated image 31. Next, the answer data from the subject side with respect to the sound data of the test sound is compared and analyzed, and the result is displayed on the test-dedicated image 31 (step S10).
Then, the sound data of the inspection sound, the sound data of the answer, the data of the analysis result, etc. are edited and recorded in the designated storage medium (step S11).
Thereafter, it is determined whether or not there is an instruction to end editing / recording of the audio data (step S12), and the process is continued until an end instruction is issued.

FIG. 22 is a flowchart showing the operation of each part of the hearing ability test.
When the control unit 15 starts the hearing ability test (step S21), the control unit 15 enters the test sound setting mode on the inspector side (step S22) and determines whether or not the background sound is output (step S35).
Further, the examination sound setting mode is entered also on the subject side, and the setting operation is enabled (step S41).
In setting on the inspector side, the setting program is sequentially executed in accordance with the selection operation of the inspector.
First, it is determined whether the recording data or the MIDI sound has been selected for the sound source to be inspected (step S23). When the recording data side is selected, the digital recording data is read (step S24).

Next, after setting the reproduction sound frequency and sound emission level to output the inspection sound (step S25), the stereo balance is set (step S26), and the repetitive reproduction is set as the reproduction method (step S27). .
On the other hand, when the MIDI sound side is selected in step S23, the MIDI data is read (step S28).
Subsequently, after setting the GM program number based on the instructor's command (step S29), the MIDI parameter is set (step S30), and the MIDI output level is set (step S31).
Note that the contents of the MIDI parameter are the pitch, pitch, rhythm / tempo, sound quality, melody, etc. of the MIDI sound.

The setting on the subject side is shown in the flowchart of FIG. 23, and steps S43 to S50 correspond to steps S24 to S31 of FIG.
As described above, when the recording data or the MIDI sound is selected and set on each of the examiner side and the examinee side, the control unit 15 performs a predetermined software process for synthesizing the voice data (step S32). Is output.
Subsequently, audio data mixing processing by the mixer 17 is performed, and the DSP constituting the audio signal processing unit 18 is caused to perform digital signal processing of the audio data (step S33).
Since the digital audio signal resulting from these processes is sent to the D / A converter 9, the analog-converted audio signal is output to the audio adjustment unit 10 side.
Thereby, since the test sound is emitted from the main headphone 21 and the sub headphone 22, both the tester and the subject can listen to the test sound.

While the inspection sound is being emitted, the control unit 15 determines whether or not to stop the generation and reproduction of the audio data (step S34). If there is a stop command, the generation and reproduction of the audio is terminated.
Here, if there is no stop command, the process is continued. Therefore, the process proceeds to step S22 on the inspector side and step S41 on the subject side, and either designated recording data or MIDI sound is generated or reproduced, and the audio data Will be output by each.
These audio data are converted into analog signals through processing by the DSP, whereby an analog audio signal is sent to the audio adjusting unit 10 side.
The audio adjusting unit 10 outputs an analog audio signal finely adjusted according to the inspection.
Thereby, since the test sound is emitted from the main headphone 21 and the sub headphone 22, both the tester and the subject can listen to the test sound.

Note that not only the test sound but also the background sound is emitted depending on the content of the hearing ability test.
When the hearing ability test is started, if there is a designation for outputting a background sound (step S35), the control unit 15 reads the background sound data (step S36).
Next, after setting the frequency and output level of the background sound (step S37), software processing of the audio data is performed (step S38).
Subsequently, the DSP is caused to perform digital signal processing of audio data (step S39).
The digital audio signal from the DSP is output to the audio adjustment unit 10 in a state where the analog signal of the background sound is superimposed on the analog signal of the inspection sound by the D / A converter 9.
For this reason, both the examiner and the subject can hear the examination sound and the background sound.
While such sound is being emitted, the control unit 15 determines whether or not repeated reproduction is instructed (step S40). If there is an instruction for repeated reproduction, the control unit 15 proceeds to step S36 and reads background sound data. The background sound is output together with the inspection sound. On the other hand, if there is no repeat playback command, the output of the background sound is terminated.

FIG. 24 is a flowchart showing the initial setting operation of the inspection sound source.
In the hearing ability test, when the examiner or the like selects the initial setting of the sound source from the selection items, the control unit 15 shifts to the initial setting mode (step S51), and processes the input information (step S52).
When digital recording data, MIDI sound source data, and examination type information are sequentially transmitted as the input information, setting processing for each is performed (step S53).
First, in the case of digital recording data, the recording file name, output frequency, stereo balance, volume level, and the like. The recorded data includes Stereo, 44.1 KHz, 16 bit, WAV format and the like.

Next, the MIDI sound source data includes a GM type, a note number thereof, volume data, and the like.
Further, the examination type information includes two sound source sound emission modes, sub-mouse information recording mode, and operation mode setting status thereof.
The control unit 15 sequentially displays these setting information on the screen 13a (step S54). Therefore, the inspector or the like can perform the setting operation while confirming the input content.
Thereafter, the control unit 15 determines whether there is a setting change or an inspection item change. If there is a change, the control unit 15 returns to step S52 and continues the processing of the input information.
On the other hand, if there is no change, it is determined whether or not there is a setting end command (step S56), and the setting operation is ended when the setting end command is input.

FIG. 25 is a flowchart showing the operation of each test item in the hearing ability test.
In this hearing ability test, the examiner explains in advance the answering method for each test item to the subject.
When the examiner selects the hearing ability test on the screen 13a shown in FIG. 19, the control unit 15 shifts to the examination type selection mode (step S61), the same discrimination ability test, the tuning test, the memory ability test, the tinnitus It is determined which of the inspections has been selected (step S62).
Here, when the inspector selects the discrimination discrimination ability inspection, as shown in FIG. 20, the inspection items are displayed and it is determined whether the pitch, pitch, volume, rhythm / tempo, sound quality, or melody is designated. (Step S63).
Here, when the inspector designates a pitch, for example, the “pitch difference discrimination ability test” is confirmed.
Also, when specifying the pitch, the “same pitch discrimination ability test”, when specifying the volume, “sound volume discrimination ability test”, when specifying the rhythm / tempo, the “rhythm / tempo discrimination ability test”, When specified, the “sound quality discrimination ability test” is determined, and when the melody is specified, “melody difference discrimination ability test” is determined.

On the other hand, if the designation of the pitch check is determined following the determination of the tuning check in step S62, the “pitch tuning ability check” is confirmed.
In addition, "pitch tuning ability check" when pitch is specified, "volume tuning ability check" when volume is specified, "rhythm tempo tuning ability check" when rhythm / tempo is specified, "tone tuning" when sound quality is specified “Ability inspection” and “Melody tuning ability inspection” are determined when melody is specified.
In addition, if any of pitch, pitch, volume, rhythm / tempo, sound quality, or melody is specified after the memory capacity test is specified in step S62, the memory capacity test for each item is confirmed.
If the tinnitus test or the like is specified in step S62, the determination in step S63 is passed and the process proceeds to the next step.

As described above, when the inspector performs a start operation as the inspection items are confirmed, the control unit 15 starts the definite inspection (step S64) and causes the timer 14 to start counting time (step S65).
Thereafter, the control unit 15 advances the hearing ability test in accordance with the operation of the main / sub mouse 24, 25.
First, the inspection data related to the confirmed inspection content is output (step S66), and the answer data when responding to the inspection is output (step S67).
The inspection data and answer data differ depending on the content of the inspection, and the output timing of each data also differs.

As the examination progresses, the control unit 15 processes answer data for the examination data (step S68).
During this time, the time data from the timer 14 is received and counted up (step S69), and during the inspection time, the inspection progress is stored in the memory 14 or recorded on the disk according to the command (step S71).
During this operation, the control unit 15 determines whether or not there is an input to stop inspection (step 70). This test stop is signaled to the examiner by the examinee confirming the signal, but the examinee clicks the right button of the sub mouse 25 or the examiner clicks the main mouse 24. When the inspection stop button 37b is clicked, a stop command signal is sent.
Here, when a stop command is input, the control unit 15 ends the inspection (step S72).
Thereafter, the control unit 15 analyzes the inspection result according to the inspection content based on the data stored in the memory 19 (step S73). Further, the inspection progress and analysis results are edited and stored in the memory 19 or recorded on the disk, and then a series of inspections is completed (step S74).

Next, a description will be given of each inspection method such as the same discrimination ability test, the tuning ability test, and the memory ability test that is confirmed in step S63 and started in step S64.
First, in the case of the “pitch difference discrimination ability test”, the control unit 15 outputs the data of the main test sound and the sub test sound as the test data.
The main test sound causes the sound source unit 4 to output pure tone (sine wave audio signal of a predetermined frequency) in response to the operation of the main mouse 24, and the sub test sound is a living environment of a predetermined condition stored in the memory 19 in advance. Data of a plurality of types of sounds generated below (in this example, a daily sound of a predetermined decibel that a general person can experience) is output.

These main / sub audio data are converted into analog signals, adjusted to a predetermined level by the audio adjusting unit 10, and emitted from the main / sub headphones 21, 22 as inspection sounds.
Thus, the subject can listen to pure sounds and daily life sounds with the left and right ears. Therefore, the inspector operates both the main mouse 24 and the sub mouse 25 to output the same sound from the sound adjusting unit 10 and emit the sound from the main and sub headphones 21 and 22 at the same time. Is set arbitrarily, and then the subject listens to this and performs the test by determining the difference between the two pure tones.
Then, by recognizing the degree of difference between the inspector's pitch position 32g and the examinee's pitch position 32g displayed on the examination-dedicated display screen 31, the subject's pitch difference discrimination ability can be enhanced. It can be accurately grasped.

In the case of the “sound pitch discrimination ability test”, the above-described inspection process is used to listen to two predetermined pitch test sounds, and the subject listens to them, and the subject determines the difference between the two pitches. The inspection is performed by making it judge.
The degree of difference is recognized by the inspector's pitch position (keyboard display mark 32e) and the subject's pitch position (mark 32e) displayed on the test-dedicated display screen 31. It is possible to know exactly the ability of the person to distinguish the pitch.
In the “Rhythm / Tempo Dissimilarity Discrimination Ability Test”, the test sound of two predetermined rhythm tempos is listened to by the subject, and the subject listens to the difference between the two rhythms and tempos. The inspection is performed by letting you judge.
By recognizing the degree of this difference from the test result displayed on the test-dedicated display screen 31, it is possible to accurately know the ability of the subject to discriminate between rhythm and tempo.

In the case of the “sound quality discrimination discrimination test”, two sounds based on a specific instrument sound or other sound source data playback sound are set in advance and listened to as the test sound, and the subject makes these two instrument sounds. And whether the sound quality of the reproduced sound of the sound source data matches.
The degree of coincidence is recognized by each display position on the test-dedicated display screen 31, that is, the inspector pitch position (mark 32e) and the subject pitch position (mark 32e) corresponding to the sound quality data. Thus, it is possible to accurately know the sound quality discrimination ability of the subject.
The instrument sound is generally a piano or a violin, but other instruments may be used. Further, not only musical instrument sounds but also human voices may be used. In this case, instead of examining the sound quality between the instrument sounds, the discrimination ability of the sound quality may be examined by emitting a human voice to the instrument sound. This person's voice can be backspoken or spoken.

In the case of the “Melody Distinguishing Ability Test”, the subject listens to one correct melody, then the subject listens to multiple melodies, and the same melodies are received from them. Perform an alternative set of tests that the examiner chooses.
Further, not only the melody but also the pitch, pitch, volume, rhythm / tempo, and sound quality can be checked in an alternative manner.
In addition, in each said discrimination discrimination ability test | inspection, a test subject's audio | voice memory ability can also be test | inspected.
In this case, when the control unit 15 performs each discrimination discrimination ability test, the control unit 15 stops the hearing after listening to the main test sound and the like, and after passing a predetermined test time, It is determined whether or not the answer matches the inspection sound.
Thereby, it is possible to easily know the degree of storage ability of the subject's voice and the like.

Subsequently, in the case of “pitch tuning ability test”, the tester listens to the test sound of a predetermined pitch after the tester has set an arbitrary value by the above-described test process, and the tester side It is determined whether or not the pitch matches this.
The inspector operates the main mouse 24 to arbitrarily set the pitch of the pure tone, and then prompts the subject to operate the sub mouse 25 to emit the pure tone at the same height.
That is, in the pitch tuning ability test, the subject side operates the sub mouse 25 to change the subject side sound so as to match the pitch set as the test sound.
Then, when the subject feels that the test sound has been adjusted, the subject may press the mouse button on the sub mouse 25.
At this time, the control unit 15 determines whether or not the pitch on the subject side matches the pitch on the examiner side based on each output data (pitch matching).
Then, by recognizing the degree of coincidence from the inspection result displayed on the inspection-dedicated screen 31, the pitch tuning ability of the subject can be accurately known.

In the case of the “pitch tuning ability test”, the tester listens to a test sound having a predetermined pitch after setting it to an arbitrary value, and determines whether or not the tester's pitch matches this.
Then, by recognizing the degree of coincidence from the test result, the pitch tuning ability of the subject can be accurately known.
In the case of the “volume tuning ability test”, the tester listens to the test sound having a predetermined volume after setting to an arbitrary value, and determines whether or not the volume on the subject side matches this. Then, by recognizing the degree of coincidence based on the degree of coincidence between the subject side 35 h displayed on the examination-dedicated screen 31 and the subject side 35 h, the volume tuning ability of the subject is accurately known. be able to.

In the case of “rhythm / tempo tuning ability test”, a predetermined rhythm / tempo test sound is heard, and it is determined whether or not the rhythm / tempo on the subject side matches this.
The degree of this coincidence is the same as that of the cursor 39f for adjusting the pitch of the background sound function display unit 39 on the examiner side activated simultaneously with the start button 38d for generating the background sound and the background sound function display unit 39 on the subject side. By recognizing the degree of coincidence with the pitch adjustment cursor 39f, it is possible to accurately know the rhythm / tempo tuning ability of the subject.
In the case of “sound quality tuning ability inspection”, the inspector causes the main mouse to generate a plurality of instrument sounds and sound data reproduction sounds set in advance on the inspector side keyboard 32a.
As a result of the operation of the sub-mouse 25 by the subject, the subject listens to it as a test sound, and a plurality of instrument sounds and sound data reproduction sounds set in advance on the subject-side keyboard 32a as with the tester. Thus, it is determined whether or not the sound quality to be generated matches the sound quality of the inspection sound.
The degree of coincidence is recognized by the degree of coincidence between the inspector-side keyboard display mark 32e and the subject-side keyboard display mark 32e on the examination-dedicated screen 31, thereby accurately knowing the sound quality tuning ability of the subject. be able to.

In the case of “melody tuning ability test”, it is possible to listen to a pre-recorded melodic test sound and determine whether or not the melody created by the subject clicking the button of the sub mouse 25 on the keyboard follows this. To do. Then, by recognizing the degree of follow-up based on the inspection result, it is possible to accurately know the melody tuning ability of the subject.
In this way, by making the left and right ears listen to the test sound and discriminating the results, it is possible to accurately grasp the various hearing abilities of the subject.
In these inspections, pure sounds are used as main inspection sounds, but natural sounds, human voices (back and voices), music sounds, and instrument sounds may be used. In this case, use the test sound as the piano sound and release the same piano sound as the answer sound, or record the subject's confidence voice and let your voice sound out against the piano sound. Also good.
According to the present invention, the subject's own voice can be used as the main inspection sound and the auxiliary inspection sound. Electronic sound or any sound produced by recording can be used as the inspection sound.
Moreover, although the test sound was heard in the left and right ears of the subject, each hearing ability may be tested by listening to either the left ear or the right ear.
Thereby, it is possible to accurately know the difference in hearing ability between the left and right ears. The difference in hearing ability also reveals the dominant ear discrimination and conversely the difference in listening ability.

By the way, although the daily life sound is used as the sub-inspection sound in the inspection, the sound collected in a general household may be used as the daily life sound. It should be noted that such daily life sounds are collected by setting a certain condition for the type of noise in advance, thereby avoiding the problem of being different for each examination.
This makes it possible to test the hearing ability of the subject under a more realistic situation in accordance with daily life, unlike the case of using a quiet examination room as in the past.

In addition, in each said tuning capability test | inspection, a test subject's audio | voice memory capability can also be test | inspected.
In this case, when the control unit 15 performs each tuning ability test, the control unit 15 stops the main test sound after listening to the subject, and after a predetermined test time, the answer of the test subject It is determined whether or not the inspection sound changes or changes.
Thereby, the memory ability with respect to the voice of the subject can be easily known as in the case of each discrimination discrimination ability test.
Also, when performing the same discrimination ability test and the tuning ability test, the test items of pitch, pitch, volume, rhythm / tempo, sound quality and melody can be combined.
Further, in each of the same discrimination ability inspection or each tuning ability inspection, it is possible to inspect different items in combination under a certain condition.
Through these examinations, the hearing ability of the subject can be recognized from a wide variety of perspectives.

By the way, when the tinnitus inspection is performed, it is inspected which one of eleven kinds of pure sounds, band noise or white noise is most similar.
In this case, the frequency is continuously changed by the slider operation unit 32c, the sound of which frequency (or the sound of the frequency band) is examined to be similar to the noise, and after confirming this, the tinnitus is regarded as similar. Check for the volume.
Further, in this tinnitus test, it is possible to perform an inspection as to how much band noise will block the tinnitus.
In addition to the use of pure tone or instrumental sound as the previous test sound, it is possible to perform intonation test using recorded speech.
In addition, the information processing device is not limited to the popular personal computer or the portable personal computer 2 as long as the device can easily collect data that can be used to determine whether or not the non-inspector can adjust the sound level. May be used.
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
