摘要

The equipment has a signal source delivering a test signal that is not directly coming from an input signal (ES). A measuring device measures a response signal that comes from the test signal. An evaluation and controlling device adjusts a parameter of a feed back reducing device (6). An information signal is delivered by the equipment such that the information signal is delivered from the source and used as the test signal. An independent claim is also included for a method for feedback elimination with a hearing aid equipment.
