Abstract (en)
[origin: EP1309225A1] The wearer inserts the hearing aid. It is subjected to an input signal (I). This leads to higher amplification (VA) than a supposed feedback threshold. The forward path amplification (VKS) is measured and equated to the feedback threshold (VKRIT) <??>An Independent claim is included for a corresponding hearing aid with adjusted critical feedback threshold.
