Functional testing and/or adjusting method for hearing aid by deriving signal transmission behavior from electrical signals read from hearing aid

摘要

The method involves stimulating the person with an acoustic or electromagnetic signal, reading the electrical input signal from an input transducer, or a signal derived from it, from the hearing aid, and transmitting this signal to an external processor unit (10). Signal levels derived from the transmitted signals are graphically represented in different frequency bands using the external processor unit. An Independent claim is included for a system for functional testing and/or adjusting a hearing aid.
