METHOD OF DETECTING A SUDDEN CHANGE IN A FEEDBACK/ECHO PATH OF A HEARING AID

A method of detecting a sudden change in a feedback/echo path of a hearing aid is based on a gradient of an adaptive filter comprising an adaptive algorithm configured to estimate the feedback/echo path. The method may comprise comparing a smoothed and processed version of the gradient values over t...

Beschreibung
Zusammenfassung:	A method of detecting a sudden change in a feedback/echo path of a hearing aid is based on a gradient of an adaptive filter comprising an adaptive algorithm configured to estimate the feedback/echo path. The method may comprise comparing a smoothed and processed version of the gradient values over time to a threshold value. A hearing aid configured to detect a sudden change in a feedback/echo path is furthermore provided.
