Method for adjusting a hearing device as well as an apparatus to perform the method
View Patent ↗A method and an apparatus for adjusting a first hearing device based on adjustments of a second hearing device are disclosed. The method comprises the steps of converting an acoustic test signal into an electric test signal by a microphone of the second hearing device, of converting an acoustic signal generated by a receiver of the second hearing device into an electrical signal, of analyzing the electrical signal in an analyzing unit, and, finally, of adjusting the first hearing device based on results obtained in the analysis performed in the analyzing unit. By the present invention, an especially suitable procedure for performing the initial adjustment of a new hearing device is achieved. The method according to the present invention quickly leads to spontaneous user acceptance of the newly adjusted (i.e. fitted) hearing device, whilst considerably reducing the required fitting effort compared with today's state of the art techniques.
1. An apparatus comprising:
a first hearing device;
a second hearing device;
a loudspeaker generating an acoustic test signal;
a couple element including a measurement microphone; and
a control unit is connected to the loudspeaker; wherein
the acoustic test signal is fed to a microphone of the second hearing device in which another acoustic signal is generated that is recorded by the measurement microphone of the couple element, the measurement microphone being connected to the first hearing device which is connected to the control unit.
2. The apparatus of claim 1 , wherein a further couple element is provided to couple a receiver of the first hearing device with a microphone of the second hearing device.
3. The apparatus of claim 1 or 2 , wherein the acoustic test signal is a stationary or a speech-modulated noise.
4. The apparatus of claim 1 or 2 , wherein the acoustic test signal is an un-modulated noise with a sound-level step of preferably 15 dB.
5. The apparatus of claim 1 or 2 , wherein the acoustic test signal has a sound-level of at least 90 dB.
6. The apparatus of claim 1 , wherein the adjustment in the first hearing device is applied to all available hearing programs.
7. An apparatus comprising:
a first hearing device;
a second hearing device;
a couple element including a measurement microphone;
a further couple element; and
a control unit; wherein
a receiver of the first hearing device is coupled to the microphone of the second hearing device by the further couple element and the receiver of the second hearing device is coupled to the measurement microphone of the couple element, the measurement microphone being connected to the first hearing device, and the control unit being connected to the first hearing device.
8. The apparatus of claim 7 , wherein a loudspeaker is operatively connected to the control unit.
9. The apparatus of claim 7 or 8 , wherein the acoustic test signal is a stationary or a speech-modulated noise.
10. The apparatus of claim 7 or 8 , wherein the acoustic test signal is an un-modulated noise with a sound-level step of preferably 15 dB.
11. The apparatus of claim 7 or 8 , wherein the acoustic test signal has a sound-level of at least 90 dB.
12. The apparatus of claim 7 , wherein the adjustment in the first hearing device is applied to all available hearing programs.
13. The apparatus of claim 7 , wherein said control unit is adapted to utilize said couplings such that settings of said first hearing device are adjusted to closely match settings already present in said second hearing device.
14. The apparatus of claim 1 , wherein said control unit is adapted to utilize results from said another acoustic test signal for adjusting settings of said first hearing device to closely match settings already present in said second hearing device.
15. An system comprising:
a control unit;
a speaker for generating an acoustic test signal based on an input from said control unit;
a second hearing device including a second microphone for receiving said acoustic test signal and also including a speaker for generating an acoustic output signal from said acoustic test signal, said acoustic output signal based on a second transfer function of said second hearing device;
a coupler including a third microphone for receiving said acoustic output signal from said second hearing device, said coupler being acoustically connected to said second hearing device by a known transfer function;
a first hearing device including a first microphone and an audio input electrically connected to said third microphone; and
an analyzing unit for analyzing wherein
said control unit is external to said first and said second hearing device, and wherein
said control unit is connected to said first hearing device via a control connection for controlling the adjustment of a first transfer function of said first hearing device based on said acoustic output signal of said second hearing device.
