As previously explained above, the objective of the invention is is that first hearing devices 3 is found out as far as possible with the hearing devices of second hearing devices 2 and set approaching setting.Can reach the spontaneous approval of high level when like this, the user puts on first hearing devices 3 for the first time.These hearing devices initial settings are the further fine tuning of hearing devices setting and the fabulous starting point of optimization.
The following describes this foundation method of the present invention:
In the first embodiment of the present invention, when the beginning engagement process, first hearing devices 3 is set to so-called measurement pattern, under this measurement pattern, determine the transmission characteristic of second hearing devices 2 and send control unit 1 to, can be by the parameter group of first hearing devices, 3 explanations by the cooperation software that control unit 1 is carried out the information translation one-tenth that receives.In addition, this cooperation software control and monitor the process of whole adjustment first hearing devices 3.Similarly, show all possible instruction or error messages by control unit 1 to hearing teacher.
Control unit 1 for example can use the standard sound card that uses in the personal computer of being everlasting to drive loud speaker 6.
As the front is mentioned, the coupling element 5 of second hearing devices 2 and known its transfer function is connected, this coupling element 5 contains measures microphone 4, probe microphone (according to IEC standard 126: be used for the 2cc coupler HA-1 of ITE (being the ear hearing devices), perhaps be used for the HA-2 of BTE (being hearing devices behind the ear)) preferably.The audio frequency input that is provided to first hearing devices 3 from the output signal of measuring microphone 4, to analyze therein.Can utilize one group of bank of filters that is used for the signal processing under the usual manner of in first hearing devices, setting up, be present in the signal that audio frequency is imported 10 places under the analysis to measure pattern.Simultaneously, the microphone 3a of first hearing devices 3 picks up from the sound 20 of loud speaker 6 and serves as a benchmark microphone with definite loudness or sound pressure level, and by the acoustic emission 20 of control unit 1 control from loud speaker 6.This can also calibrate first hearing devices 3.Here, these two hearing devices 2 and 3 should be put very near each other, thereby the two is exposed in the identical acoustic emission.In addition, only when microphone 2a and 3a do not pick up the back drop signal, just can reach the best fit of first hearing devices 3.Therefore, it is useful whole configuration being placed in the absorption chamber.In addition, expection can be disturbed by appropriate algorithm detection noise and other in control unit 1, thereby can eliminate wrong measurement data (the artificial eliminating).
Now provide different sound test signals 20, for example the different white noise of sound level to this configuration.Alternatively, also can be used as possible test signal to sinusoidal sound, sing sound/swing acoustical signal and voice signal or music.By record stem from the coupler 5 receiver 2b's and by measuring the acoustical signal 21 that microphone 4 picks up, can in first hearing devices 3, determine the transfer function of second hearing devices 2.In addition, can utilize the time constant of the compression that the instantaneous performance of transition test signal 20 (for example level saltus step) assessment for example uses.
Based on this measurement data, can adjust first hearing devices 3 now so that the one the second hearing devices 2 become similar as far as possible with 3 separately transfer functions.
Point out that the second measured hearing devices 2 can be any hearing devices.And first hearing devices 3 of " newly " must possess enough frequency resolutions and must have can with plain mode with measure the audio input end 10 that microphone 4 is connected.
Measurement is to carry out in quiet as far as possible room, and this also is necessary to the news threshold of the feedback of measuring hearing devices being heard threshold or impaired hearing person, satisfies this requirement in the facility that hearing teacher is used for measuring automatically.
Second hearing devices 2 is attached on the coupling element 5, if the latter can be so-called " 2cc coupler ".The 2cc coupler is according to 126 definition of IEC standard (referring to the data of above-mentioned Richard C.Seewald work), but as long as also can use other coupler in the chamber that is inconjunction with existence qualification under the suitable connection, because always can convert the 2cc value of standard to, replace standard microphone, a pick-up that has the passage that is used for probe tube is inserted into this coupling element 5.Actual measurement microphone for example comprises the audio frequency boots (referring again to the data of IEC standard 126 or above-mentioned Richard C.Seewald work) of a RECD (being that real ear-coupler is poor) guiding, and the latter's probe tube protrudes in the 2cc chamber through this pick-up.
According to a preferred embodiment of the present invention, respectively first and second hearing devices 2 and 3 are placed on the plane surface, thereby two hearing devices 2 and 3 microphone 2a and 3a separately is close to each other.The loud speaker 6 that serves as the sound source that produces test signal 20 is positioned at from the distance of microphone 2a and the about 50cm of 3a last.
Such as noted, in order to measure, by white noise or the ICRA noise that loud speaker 6 reappears stably or voice are modulated.Title at W.A.Dreschler, H.Verschuure, C.Ludvigsen and S.Westermann is " ICRA Noises:Artificial NoiseSignals with Speech-like Spectral and Temporal Properties for HearingAid Assessment " (Audiology, Vol.40, No3, May-June 2001, PP.148-157) provide the definition of ICRA noise in the literary composition.The sound card of the personal computer by serving as control unit 1 produces test signal 20 and sends to loud speaker 6.
In order to calibrate first hearing devices 3, loud speaker 6 reproduces the test signal 20 that is made of steady white noise.Read the average input sound level of calculating in first hearing devices 3, and if desired, as long as adjust not excessive spectral property and the sound level that just can revise the acoustical signal that is produced according to these readings.Otherwise then notify the semaphore of hearing's teacher loudspeaker reproduction insufficient.If can not compose correction, still can carry out this method, although result's implication is subjected to some restrictions in this case by control unit 1.
Before calibration acoustic emission level and afterwards, determine that according to identical process the spectrum of the background noise in the test cabinet is flat.Notify hearing teacher if this noise level is too high, for example by control unit 1.
For example, first measurement comprises by loud speaker 6 reproduces (as above-mentioned) zoop as sound test signal 20, and wherein sound level signal is taken as 50,65 and 80 decibels in succession.In coupling element 5, catch the response of second hearing devices 2.Should for example reproduction of voice of concrete response expression modulation signal.
Second measures and for example to comprise by loud speaker 6 and reproduce (as above-mentioned) not zoop as sound test signal 20, wherein, sound level signal is set to 65 decibels value.In coupling element 5, catch the response of second hearing devices 2.The reproduction of this response expression steady noise.Can determine the noise removing degree from the difference between first and second measurement results.
If desired, the 3rd measurement for example comprises the not zoop that reproduces as sound test signal 20 by loud speaker 6, and wherein sound level signal jumps 25 decibels (for example, since 55 decibels in the middle of cycle tests, then jump to 80 decibels, 55 decibels of rebounds when finishing then).In the response of from coupling element 5, catching, can determine to adjust the order of magnitude of time constant and decay.
A kind of the 3rd alternative measurement for example comprises by loud speaker 6 reproduces the real speech signal of the output sound level with 65dB or the zoop signal (as above-mentioned) of equivalence as sound test signal 20.The distribution of amplitudes function (being distribution map) of the signal that captures by analysis can be determined the time constant of effective dynamic compression and compact model.The back can be to this further explanation.
Effective dynamic compression of signal is by following definite: at first, determine typical modulation signal, for example sound pressure level (SPL) is 65 decibels a voice signal, input signal dynamic range.For example the difference between medium 10 and the 95th five equilibrium of the amplitude density fonction percentage five equilibrium that records by calculating obtains dynamic range values.The then signal of catching by microphone 2a and having handled by second hearing devices 2 at identical methods analyst.The ratio of dynamic range values that at first obtain and that then obtain produces the effective compression ratio by the completed signal processing of second hearing devices.
Carry out identical measurement if be used to modulation signal in addition, resulting result's ratio produces the Static Compression ratio.
On the other hand, can be by the following time constant of determining this compression control loop:
Calculate modulation spectrum signal and the same signal that is untreated that 2 pairs of voice signals of second hearing devices or voice type modulation signal are handled.Because the dynamic compression control loop serves as high pass filter, the difference between above mentioned these two modulation spectrums typically shows the high-pass features that has certain cut-off frequency.This cut-off frequency is the direct measurement result of time constant of control loop of the compact model of this employing.
First result who measures is used for setting the I/O function of different passages.Difference between second and first measurement is used for setting the noise removing degree.If the time constant of gain control circuit belongs to the parameter of cooperation, can utilize the 3rd to measure this adjustment time of adjustment.
If hearing devices comprises different selectable hearing programs (Program), in second hearing devices 2 that will be measured, one after the other encourage these different hearing programs, and each possible hearing program is repeated measuring process described above respectively.
Preferably should be the situation that its adaptation is characterized by medium sound level of adjusting to is set in the volume control of the second measured hearing devices 2.This means the comfortable conventional setting of listening to that adapts under the quiet environment, for digital hearing devices, this is the setting that tuning back typical case selects immediately on this hearing devices.
Set if also need to determine the amplitude limiter of the hearing devices measuring, also must make second hearing devices 2 be exposed to 90 decibels of SPL test signals and must carry out the measuring process that illustrates previously.For hearing teacher and 90 decibels of SPL signals of hearing device user all is that bent type is very uncomfortable.
Fig. 2 describes another embodiment of the present invention, wherein only by produce under the help of first hearing devices 3 sound test signal 20 aspect this on this embodiment different with the embodiment shown in Fig. 1.In order to realize this point, need another coupling element 50 between second and first hearing devices 2 and 3.Just need loud speaker 6 for above-mentioned calibration process.Now in the major part of in first hearing devices 3, carrying out signal processing under the control of control unit 1.On others, adopt the identical measuring process that illustrates down together with the configuration of representing among Fig. 1; Thereby do not need other to be exclusively used in the explanation of this second preferred embodiment of the present invention.
