Method and device for analyzing hearing aid settings

1. A method for transferring a hearing aid device setting from a first hearing aid device to a second hearing aid device, wherein the first hearing aid device and the second hearing aid device each include an acousto-electric converter and an electro-acoustic converter, which comprises the steps of:

acoustically coupling the electro-acoustic converter of the first hearing aid device to the acousto-electric converter of the second hearing aid device by means of a coupling device;

exposing the acousto-electric converter of the first hearing aid device to an acoustic test signal;

detecting an acoustic output signal of the electro-acoustic converter of the first hearing aid device by means of the acousto-electric converter of the second hearing aid device; and

evaluating a detected acoustic output signal;

determining a setting parameter for the second hearing aid device based on the evaluation of the detected acoustic output signal, wherein the setting parameter is determined such that a transfer function of the second hearing aid device is approximated to the transfer function of the first hearing aid using the setting parameter; and

setting the second hearing aid device based on the determined setting parameter.

2. The method according to claim 1 , which further comprises generating the acoustic test signal by a further electro-acoustic converter.

3. The method according to claim 1 , wherein the acoustic test signal is an ambient noise and the method further comprises the step of detecting the acoustic test signal by means of an acousto-electric reference converter.

4. The method according to claim 1 , which further comprises performing the evaluating of the detected acoustic output signal at least partially in the second hearing aid device.

5. The method according to claim 1 , which further comprises performing the setting of the second hearing aid device by an operator.

6. The method according to claim 1 , which further comprises performing the setting of the second hearing aid device via a signal connection to the second hearing aid device.

7. A device for transferring a hearing aid device setting from a first hearing aid device to a second hearing aid device, the device comprising:

a coupler for acoustically coupling of an electro-acoustic converter of the first hearing aid device to an acousto-electric converter of the second hearing aid device; and

an analyzer receiving and analyzing a signal with information from the acousto-electric converter from the second hearing aid device;
