  • the second hearing aid 2 also has a microphone 2a and a handset 2b, wherein this with a coupling element. 5 is completely covered, leaving a closed Cavity arises. In this cavity is also a Measuring microphone 4, whose signal is the audio input 10 of the first hearing aid 3 is acted upon.
  • a well-known Coupling element for use in the present invention is for example in Phonak Focus No. 20 with the title "The Desired Sensation Level (DSL) Method for Hearing Aid Fitting in Infants and Children "(Richard C. Seewald, 1995) described. An identical publication is in the Pamphlet titled "DSL 4.0 Handbook" by the same Author included.
  • the goal of the present invention in a hearing aid setting for to find the first hearing aid 3, that of the second Hearing aid 2 is as similar as possible.
  • This can be a high spontaneous acceptance when first wearing the first Hearing aid 3 can be achieved.
  • This first Hearing aid setting is then excellently as Starting point for further fine adjustments and optimizations the hearing aid settings.
  • the first hearing aid 3 at the beginning of the adaptation in a so mentioned measuring mode in which the Transmission properties of the second hearing aid 2 analyzed and transmitted to the Control Unit 1.
  • the fitting software executed in the control unit 1 transforms the received information into a Parameter set, which understood by the first hearing aid 3 can be.
  • the entire course of the Adjustment of the first hearing aid 3 by the Adjusting software controlled or monitored.
  • control unit 1 In the control unit 1 is used to control the Speaker 6, for example, a so-called sound card used, as in conventional personal computers is used.
  • the second hearing aid 2 having a known transmission characteristic Coupling element 5 coupled to the measuring microphone 4, preferably in the form of a probe microphone (according to IEC standard 126 2cc coupler HA-1 for ITE (in-the-ear) hearing aids or HA-2 for BTE (Behind The Ear) hearing aids).
  • the signal of the measuring microphone 4 is transmitted via the Audio input 10 fed into the first hearing aid 3 and in analyzed.
  • the microphone 3a of the first hearing device 3 takes the sound of the speaker 6 and serves as Reference microphone to determine the volume or the Sound level and to control the Schalldarbietung over the control unit 1.
  • test signals such as white Noise with different levels.
  • test signals are but also sinusoidal or sinusoidal signals, wobble tones, natural language or music conceivable.
  • transient test signals 20 e.g., level jumps
  • the first hearing aid can now be used 3 can be set so that the transfer functions of the first and second hearing aids 3 and 2 are similar be possible.
  • the second, to be measured Hearing 2 can be any hearing aid.
  • the new first hearing aid 3 has a frequency resolution and via an audio input 10 to which a simple Coupling of the measuring microphone 4 is possible.
  • the measurement is done in a quiet room - what by the way also for the measurement of the feedback threshold of a Hearing aid or hearing threshold of the hearing impaired is required.
  • the conditions at the for the measurements required space with an acoustician are therefore without another already fulfilled.
  • the second hearing aid 2 is connected to the coupling element 5 connected, which for example a so-called 2cc coupler is.
  • the 2cc coupler is according to standard IEC 126 (see above literature by Richard C. Seewald) wherein other couplers are also used can, as long as a defined volume with appropriate Coupling are available. A conversion to standardized 2cc values are possible at any time.
  • a standard microphone is an adapter with channel for a probe tube inserted into the coupling element 5.
  • the actual measuring microphone 5 forms, for example RECD (Real-Ear-to-Coupler Difference) - direct audio shoe (see again IEC 126 or the literature of Richard C. Seewald), whose probe tube over the adapter protrudes into the 2cc volume.
  • the first and the second hearing aid 2 or 3 so on a smooth surface laid that the microphones 2a and 3a of the two hearing aids 2 and 3 are close to each other.
  • the Speaker 6 which is used for sonication with test signals 20 is used, for example, is about 50 cm Distance to the microphones 2a and 3a.
  • ICRA noises Artificial noise signals with speech-like spectral and temporal properties for hearing aid assessment
  • the test signals 20 are given to the loudspeaker 6 via the sound card of the personal computer operating as the control unit 1.
  • the Speaker 6 is a stationary white noise than Test signal 20 reproduced.
  • the playback optionally spectral and in level Corrected, if not too big changes necessary are. Otherwise the acoustician will be informed that the speaker quality is insufficient. If a spectral correction via the control unit 1 not is possible, the process can still be performed become. However, the informative value of the results a bit limited.
  • the spectral background levels in the test room with the same Method determined. Is he so high that a meaningful Measurement is not possible, the acoustician, for example, via the control unit 1, accordingly informed.
  • a first measurement is, for example, that about the speaker 6 a modulated test noise (see above) as an acoustic test signal 20 successively with the Levels 50, 65 and 80 dB. in the Coupling element 5 is using the measuring microphone 4 respectively the reproduction of the second hearing device 2 to be measured detected.
  • This reproduction is representative of the Reproduction of modulated signals, e.g. Language.
  • a second measurement is that over the speaker 6 an unmodulated test noise (see above) at 65 dB as an acoustic test signal 20 reproduced becomes.
  • the reproduction of the measuring, second hearing device 2 detected. This rendition is representative of stationary sound reproduction. From the reproduction difference between the first and the second measurement is the level of noise reduction (Noise canceling) determined.
  • a third measurement is required in that on the speaker 6 an unmodulated Noise with a level jump of 25 dB in the middle of the Signal is reproduced (first 55 dB, then 80 dB and then 55 dB). From the detected in the coupling element 5 answer may be the order of magnitude of the entrance and exit times be determined.
  • the effective dynamic compression of a signal will be like follows determined: First one determines the dynamics of the Input signal of a typical modulated signal, so for example, voice at 65 dB SPL. It arises e.g. from the difference between the 10th and the 95th Percentile of the amplitude distribution. Now that will be with the Microphone 2a recorded and in the second hearing aid. 2 processed signal analyzed in the same way. The Ratio of the dynamic range determined above to the now The dynamic range obtained gives the effective Compression ratio of signal processing from the second Hearing aid 2 on.
  • the time constants of the compression control can be on the other side as follows:
  • the results of the first measurement become the setting the input / output functions of the various channels used.
  • the difference between the second and the first measurement is used to adjust the strength of the Noise Canceling. If Time constants of the gain control to the fitting parameters may include the third measurement for adjustment the decay times are used.
  • the individual programs are successively in the to be measured, second hearing aid 2 activated and with the measured method described.
  • the volume control will be the second to be measured Hearing aid 2 is preferably placed in that position, the is suitable for listening to medium sounds. This is meant a customer setting that is in for pleasant listening quiet environment is suitable. For digital hearing aids is this is usually the setting right after switching on the Hearing aid.
  • the second hearing aid 2 If the limitation of the second hearing device to be measured 2 should also be recorded (setting a limiter), must the second hearing aid 2 additionally sonicated with 90 dB become. Incidentally, the method described is used. A 90 dB performance is usually uncomfortable for the Acousticians and for the hearing aid wearer.
  • FIG. 2 shows a further embodiment of the invention, these being of the type shown in FIG Embodiment only differs in that the acoustic test signal 20 with the aid of the first hearing aid 3 is produced.
