[0001] this application requires at the calendar year 2001 U.S. provisional application No.60/340 that formerly submitted in 18th of December, 271 rights and interests, and further with the U.S. application No.10/083 that submitted on March 1st, 2002,088 is relevant.The description of these two pieces of related applications and disclosed content are all incorporated by reference at this.
Technical field
[0002] the present invention relates to treatment, more particularly, relate to and utilize phase shift to eliminate the improvement clinical treatment method and apparatus that principle is treated the mono-frequency tinnitus patient tinnitus patient.
Background technology
[0003] tinnitus is defined as when not having external sound to occur individual institute sound sensed, and often with intermittently or continue fizz, the tinkle of bells, roar, pipe, the form of clicking occurs.Claim that according to American Tinnitus Association tinnitus is perplexing and surpasses 5,000 ten thousand American, and wherein surpass 1,200 ten thousand people and suffer the torment of tinnitus so serious, make them have to seek medical attention, and many people can not orthobiosis.
[0004] tinnitus often is called as the tinkle of bells in the ear, is surpassing in the middle of 65 years old the American according to estimates, and tinnitus can appear in about 50% people.Generally speaking, tinnitus has many different forms, and these forms may be relevant with its potential origin cause of formation.Tinnitus might cause by wound, medicine, impaired hearing, normal ageing process or other unknown cause, or associated.
[0005] method of treatment tinnitus all concentrates on the tinnitus noise shielding with patient's impression before.Though shield technology in the past can not alleviate the problem of tinnitus patient, has done significant research.In the research report in the tinnitus academic conference of Oregon, person in charge Jack Vernon (Jack Vernon) in audition research center, Oregon statement: in the research of patient's tinnitus, have tangible importance during the sound that the pass of phase place and tone (tone) ties up to tinnitus shields and be vital.Vernon continues to observe, and people can not suppress to eliminate the idea of tinnitus by the phase place of suitably adjusting the external sound that uses in the middle of the shielding.
[0006] in the comment that the early stage tinnitus treatment of Wegel is found, mentions, the slight off resonance of shielding external sound generate one with tinnitus sound together as the sensation of beating time, Vernon is reported, in the research to 100 patients, he only can detect slight as the sensation of beating time in 4 examples.Therefore, Vernon is summed up: what Wegel found probably is not use one pure tone owing to Wegel as the sensation of beating time, and the scale confusion that has been to use the noise of a narrower frequency range to cause causes.In a word, Vernon is observed: phase controlling has proved further carries out patient's research, is effective to obtain shielding parameter for the tone tinnitus treatment.Vernon is about carrying out the report of suitable phase controlling in order to treat tinnitus patient, delivered at first in 1991 and be that title is collected in 1997 editions Shulman ' s treaties and begins never to change with " diagnosis of tinnitus and treatment " from it.
[0007] doctor Choy has reported in his above mentioned U. S. application from utilizing the extraneous tinnitus sound that generates to carry out the favourable patient data of the not visible clinical research of 180 degree phase shifts.The patient who is higher than 79% acceptance research claims or has eliminated tinnitus noise, has perhaps reduced the level of tinnitus noise considerably.
[0008] current medical procedures and electronics/acoustic instrument all can not or be assisted the frequency and the amplitude of the tinnitus noise of objective definite patient experiences.Also can not subjectively determine on the mono-frequency tinnitus tone of patient's reality certain any instantaneous phase.
[0009] current tinnitus treatment state makes tinnitus patient very worried, because in order to offset the actual tinnitus noise of patient, the medical knowledge of current state and audition/electronic machine also do not allow a people to determine objectively which point of patient's virtual interior living tinnitus sound wave tinnitus tone (sine wave) the sinusoidal wave insertion of external phase shift to be eliminated patient's real tinnitus noise.
Summary of the invention
[0010] in a plurality of possible embodiment of the present invention, utilize by the mono-frequency tinnitus patient is subjective and determine, with the tone that the external world that is complementary with his/her tinnitus noise frequency and amplitude generates, realized anti-phase noise cancellation to patient's mono-frequency tinnitus tone.According to applicant's a new equipment and an aspect of method, will at first impose on tinnitus patient by earphone or broadcast system by the sound wave of patient's subjective observation being specified selectively the external world's generation that is complementary with patient's tinnitus tone.Then, by a plurality of angular deflection sequence step the sound wave that the identical external world generates is carried out phase shift continuously, make in the scope of 180 degree phase shifts of the signal that is generated the skew of the sound wave in the external world at least or slide, in such bias step, when it is applied to the patient, obtain the counteracting relation opposite with patient's tinnitus tone.The tone that the tinnitus treatment sequence of the sound wave that the external world generates and the external world through phase shift then generate has been realized the elimination to patient's tinnitus tone, when the sequence step warp of the tone that generates effectively slides with tinnitus sound wave quadrature, causes tinnitus tone to be eliminated.
[0011] applicant's inventive apparatus and method can be provided in the portable self-treatment storage device, this device comprises the sequence of the tinnitus treatment tone segments of record, for example, the extraneous tone that generates and in patient's treatment clinical course or thereafter according to the successive phase shift steps of patient's clinical data record.By the continuous phase shift fragment in the playback patient treatment program, the sequence that the patient notes before can utilizing in the patient self-treatment process.

The specific embodiment
[0023] in order to remedy current deficiency in diagnosis and treatment tinnitus patient, particularly single-frequency (single-tone) tinnitus, the applicant has developed a kind of new, more effective phase place that has overcome many shortcomings of the prior art and has eliminated Therapeutic Method and device.For a long time, need a kind of effective treatment to reduce widely, alleviate always or eliminate the usually very weak state of tinnitus of mono-frequency tinnitus patient.
[0024] with reference now to Fig. 1, it shows a preferred embodiment that is used for mono-frequency tinnitus patient's phase shift treatment system with the form of block diagram.Sound generator 10, for example, Agilent33120A type forcing function generator or any waveform generator that can buy that is equal to are connected in the input of patient's earphone 12 and oscillograph 14, and this oscillograph for example can have been bought from Eektronics company in the U.S..Rising tone tone generator 16 also is connected in another input of oscillograph 14.
[0025] sound generator 10 has a plurality of knobs that can regulate 18 and 20 and lead-out terminal 24.As will at length illustrating with reference to figure 3 below, require mono-frequency tinnitus patient 11 to use knob 18 and 20 to adjust the frequency and the amplitude of the acoustical signal that sound generators 10 generate respectively, impose on the output of earphone 12 and tinnitus single-frequency sound that the patient hears is complementary up to sound generator.
[0026] " the sound typing " of this subjectivity is preferably on the not visible basis and repeats repeatedly, and just, the patient can't see oscillograph 14.Can between patient 11 and oscillograph 14 and sound generator 10, place dividing plate 36.In addition, perhaps the display that does not have patient 11 to observe on sound generator 10 perhaps shields or hiding any such display patient 11.In this manner, if the patient can subjectively repeatedly select tinnitus noise and the sound generator 10 of roughly the same parameter to mate his or she perception, just should be confident of believing the tinnitus noise that the output of sound generator 10 is accurately experienced near patient 11.
[0027] preferably carries out record for the personal voice typing data in each step in the self-typing step by the audiologist or the doctor that participate in.In addition, can generate identical output, thereby be complementary with the output of first sound generator 10 by regulating rising tone tone generator 16.The output of first sound generator 10 and rising tone tone generator 16 can compare on oscillograph 14, thereby guarantees that they are identical.As hereinafter described, can use the output of rising tone tone generator 16 to prepare patient 11 treatment record.
[0028] sound wave elimination principle is that by having the second sinusoidal wave superposition of identical frequency and amplitude, for example addition is implemented when the primary sinusoid has the phase shift of 180 degree.Sound wave is eliminated in electric and measuring technique and is known, and is widely used in the many technical fields that comprise audiology, mechanics and electronics.For single-frequency tinnitus, the patient should be able to regulate the tinnitus noise that the output of first sound generator 10 makes it hear near him or she.
[0029] can describe as follows and will have same frequency and amplitude, but the phase relation of two waveforms is known nothing for some common points first waveform and second waveform adder, thus reach the method that effect is eliminated in phase shift.Sound generator 10 is set to have first scale of frequency f 1 and amplitude A (millivolt that for example shows) on sound generator 10, and is connected in first input of multichannel oscilloscope 14.Second generator 16 also is set to have the identical scale of identical amplitude, and its output is connected to second input of oscillograph 14.
[0030] with reference to figure 2A-2E, can see the phase place of regulating sinusoidal wave f by series of steps, this sine wave is expressed as f
1... f
m, f

mAddition and cancelling out each other.For tinnitus patient regrettably, the structure of human auditory system and work than top on the basis of multichannel oscilloscope 14 the simple addition of the sound waveform of two illustrated tones more complex.
[0031] the audiology field is known is, the human and animal can quite accurately determine the direction apart from their far sound wave, and with regard to a certain degree, they can also estimate the distance of sound source.In the audiology field, carried out many experiments, wanted to analyze and implement the localized structure of so-called two ears in human and the animal body.Have two main factors to help people to determine the direction of the sound that transmits: (1) relative intensity (2) in two ears of hearer is for sine tone, phase contrast between two ears perhaps arrives the phase contrast between the sound wave of hearer's left ear and auris dextra respectively.Thereby understand that easily the hearing system of the mankind or animal can be distinguished the phase shift of complicated sound basically, and can clearly distinguish the phase shift of the sound of pure tone or single-frequency.Such auditory analysis is based on frequency, and for the frequency more than the 1KHZ, most of observers tend to determine from the ear of that side that receives bigger sound the direction of sound source.Thereby in general, carry out auditory localization for being what to determine very much for a certain frequency range in several kilo hertzs the scope by phase contrast.Such as discussed below, with reference to figure 3, in implementing tinnitus treatment, not only determine the tone quality of tinnitus signal, and definite tinnitus patient whether in two ears, only in the ear or in the head at them and do not relate to any ear (when asking about them and whether hear tinnitus such as many people said) lining hear his/her tinnitus, these all are very important.
[0032] refers again to Fig. 1, will further specify the structure and the operation of preferred embodiment of applicant's the device that is used for the treatment of the single-frequency tinnitus patient.Phase-shift network 30 can be any kind that the technical staff knows in audition and the electric field, is used for applying a required phase shift to first sound generator 10.Alternative is that sound generator 10 can have the output waveform phase-shift characterisitc.In order to select wave form phase shift feature, the operator can regulate required phase shift (weighing with angle), for example 10 degree, 20 degree etc., and this can influence required skew as shown in Figure 2, for example Δ
1, Δ
2Deng, perhaps can use suitable recloser.
[0033] as shown in Figure 1, switch 32 can be selectively sends to the output of first sound generator 10 in patient's the earphone 12.In another selectable position, switch 32 is with the output of phase-shift network, and promptly the signal from first sound generator 10 adds that phase shift sends in patient's the earphone 12.If sound generator 10 does not have phase-shift characterisitc, so just use independent phase-shift network 30.Earphone 12 is preferably and can have bought the high-quality earphone that trade mark is QuietComfort from the Bo s e company of for example State of Massachusetts, US.
[0034] as illustrated, switch 32 is after-applied in earphone 12 with the output offset of sound generator 10.As illustrated in top, from the increase of the continuous phase shift of the sine wave tone of generator 10 with respect to f
1Be to generate continuously, as shown in Figure 2, thereby pass through as f

3... f
mIllustrated step realizes 180 anti-phase degree phase cancellation relations.
[0035], there is shown a kind of tinnitus tone P (t) and the extraneous tone I (t) that produces diagrammatic representation with the theory of its mathematical equation representation addition separately with the patient with reference now to Fig. 3 A.As mentioned above, patient's tinnitus tone P (t) can not be detected by existing electronics or acoustic wave apparatus, still, discusses for convenience and analyzes, and it is expressed as the sine wave of characteristic frequency f (t).As explained above, the waveform I (t) of the waveform separately of patient's tinnitus tone P (t) and generation is based on the patient with his/her tinnitus tone oneself typing, and compares with the output of sound generator 10, as illustrated in conjunction with Fig. 1.
[0036] Fig. 3 B has illustrated representative P (t) and I's (t) and S's (t) single sine wave has initial offset or pitch angle θ, as shown in Fig. 3 A.Represent with mathematics equivalence value S (t) by it.Fig. 3 C has illustrated the amplitude of sine wave of the arithmetic sum of the ripple I (t) that representative patient tinnitus ripple P (t) and input generate.Shown in Fig. 3 C, arithmetic sum S (t) with two offset wave forms P (t) of aforementioned angular deflection amount θ and I (t) has the instantaneous amplitude less than patient's tinnitus tone sound wave, this is owing to exist the tinnitus tone cause the patient to reduce or counteracting that the angle of phase displacement θ that eliminates realizes, as and S (t) waveform on 2 π/3 such shown between 4 π/3 angles.Thereby, for shown in about 1/3rd scope of 360 degree in for, partial offset has appearred.By increasing the skew of extraneous tinnitus treatment tone I (t), when input treatment tone I (t) reaches 180 degree antiphases, we can offset or eliminate fully patient's tinnitus tone P (t) in theory, as shown in Figure 2, as described above like that, it and patient's tinnitus tone P (t) quadrature.For being had more completely, the tinnitus tone that reduces in theory and eliminate the patient understands, can be with reference to figure 3A, and 3B and 3C and following mathematical definition and relevant equation:
Patient's sine wave:
P(t)＝P
0sin2πft
P wherein
0Be amplitude, f is a frequency, and t is the time
Sine wave input from generator:
I(t)＝I
0sin(2πft-θ)
Wherein θ is the phase shift radian of P (t) and I (t), π radian=180 °, 2 π=360.
P (t) and I (t) and:
S(t)＝P(t)+I(t)＝(P
0sin2πft)+I
0sin(2πft-θ)
Suppose P
0=I
0, so
S(t)＝P0[sin2πft+sin(2πft-θ)]
＝[2P
0cos(1/2θ)]·[sin(2πft-1/2θ)]
＝Asin(2πft-1/2θ)
Wherein A is the amplitude with ripple
Thereby,
A＝2P
0cos(1/2θ)，
Sin (2 π ft-1/2 θ) is the sine wave with ripple, and
1/2 θ is the phase shift with ripple.
[0037], there is shown the logic diagram of the embodiment of the preparation of self-treatment disk 40 in the treatment clinical course that tinnitus patient is gone to a doctor with reference now to Fig. 4.Sound generator 10 is preferably similar to the 26S Proteasome Structure and Function described in top Fig. 1.As mentioned above, after tinnitus patient oneself typing, in a series of time series steps that increase progressively, to carry out suitable phase shift from the signal of sound generator 10 regulates, thereby apply the treatment tone segments that phase shift increases progressively to tinnitus patient by earphone 12, in a treatment cycle, the phase shift sum that increases progressively reaches at least 180 degree or bigger.In a preferred embodiment, can be 6 degree or 20 degree with respect to the phase shift that increases progressively of preset coordinates, or other recruitment (will be described in detail with reference to figure 8).
[0038] the tinnitus treatment tone can show on monitor or oscillograph 14-4, the tinnitus treatment tone f that makes the clinicist to monitor to increase progressively from initial tinnitus tone f to skew
mSkew, as shown in Figure 2.In the patient treatment draft, when it imposes on the patient by earphone 12, the increase of the audio signal of the patient treatment tone that audio frequency or digital memory 42 records are initial and each phase shift of initial therapy tone.What be connected to memory element 42 is CD writer or other similar audio recording device 44, and it produces Heal Thyself record or disk 40 corresponding to the output of storage device 42.In other words, memory element 42 is coupled to online transmission/receptor 46, and this transmission/receptor 46 can comprise the computer that can network or be connected to the Internet or the server of WWW.Then, can set up communication line 48 with transmission/receiving element 46 by the Internet or WWW.This circuit 48 can be selectively sends to patient's home computer or remote clinic 49 with the patient treatment data of given patient.
[0039], shown in the figure embodiment of the device of the Heal Thyself system that is suitable for domestic that can use with an alternative embodiment of the invention with reference now to Fig. 5.The tinnitus self-treatment disk 40 of distributing to a specific patient is separately followed his or her tinnitus treatment and is consigned to the patient in the clinic, as described with reference to figure 4.In other words, audio treatment data can by with 48 home PCs 49 that are transferred to the patient that are connected of the Internet or WWW.As shown in Figure 5, switch 52 optionally is coupled to the output of PC49 or CD Player 54 patient's earphone 12.Thereby, utilizing self-treatment disk 40, patient 11 can avoid the tinnitus puzzlement easily at his or her family.
[0040], schematically shows the layout of CD disk according to another embodiment of the invention with reference now to Fig. 6.CD disk 40 can comprise and have a plurality of audio recording grooves planar, the circular body 60 of (for example 62 and 64), and the audio recording groove is circular substantially, is arranged at least one surface.CD disk 60 can be any type of knowing that can buy.Dish 60 preferably has fixed replacement position or original position 66.Tinnitus treatment data can be recorded on the disk 40 by any well-known audio or digital method.Similarly, tinnitus treatment data can be stored in any other can the device of recording audio data on, comprise tape, floppy disk or CD, semiconductor memory etc., but be not limited to this.In addition, tinnitus treatment data can be stored with any audio form, comprises CD, MP 3, wa ve file (.wav) etc., but is not limited to this.
[0041], there is shown applicant's the logical flow chart of illustrative embodiment of objective estimated data's new method that is used to generate phase shift tinnitus treatment draft with reference now to Fig. 7.As mentioned above, applicant's treatment draft is the successful candidates that at first screen to determine the mono-frequency tinnitus s phase shift treatment in potential tinnitus patient, and initial screening can be carried out in conjunction with the medical science agreement of MATTP or equivalence.In addition, audiometrist can be used as the part of treatment and implements, and perhaps implements before or after treatment.In step 1, require selected single-frequency patient subjectively his/her tinnitus sound frequency to be carried out " sound typing ", for example adopt aforesaid adjustable sonic generator 10, frequency and amplitude to his/her tinnitus tone on not visible basis quantize.Preferably, require the patient that patient's subjectivity " sound typing " is repeated to guarantee several times that the patient is subjectively with the tone of the output of his/her tinnitus tone and frequency generator and the accuracy that amplitude is mated.
[0042] in step 2, the clinicist of participation or doctor physician utilize the data in the step 1 to generate identical with patient's tinnitus tone substantially suitable extraneous sinusoidal wave treatment tone.Then, the treatment tone that generates is offset in time to increase progressively by a plurality of successive substantially the same predetermined processes and reaches 180 degree, wherein, in treatment cycle or scope, the waveform that generates carries out a series of eliminations by so successive phase shift, and final and patient's tinnitus tone becomes anti-phase elimination relation, as below will further specifying with reference to figure 8 and 9.
[0043] in step 3, tinnitus patient can accept PET after completing steps 2 or functional MR I brain scan is estimated the tinnitus activity that the patient is current objectively, so that after the treatment of the people's that accepts applications phase shifted cancellation, the elimination of quantitative Analysis patient tinnitus tone or reduce amplitude substantially objectively.These processes are implemented as the part of many ongoing clinical researches.Recently, the researcher of Denmark, Sweden and France has confirmed the positive role of PET brain scan in the auditory cortex of tinnitus patient.The brain scan that should be realized that tinnitus patient can be before the phase shift tinnitus treatment carries out, among or a period of time afterwards implement, to obtain the patient treatment data of extra objective tinnitus patient.
[0044], shown in the figure a series of sequential line charts of another embodiment of layout of applicant's self-treatment disk 40 with reference now to Fig. 8 A, 8B and 8C.With reference to figure 8A, the first of tinnitus treatment or regional #1 are at an A opening entry, and some A is preferably the original position or the reset position of specified recorded trace, as previously described in reference to Figure 6.Reset position or original position are shown as t on time coordinate
