HEARING AID AND METHOD OF UTILIZING GAIN LIMITATION IN A HEARING AID

摘要

A hearing aid (200) with multiple microphonescomprises a first microphone (1) for converting sound into afirst audio signal, a second microphone (20) for convertingsound into a second audio signal, directional processingmeans for combining the first and said second audio signalaccording to a mixing ratio to form a spatial signal,estimating means for estimating a first acoustic feedbacksignal entering the first microphone and a second acousticfeedback signal entering the second microphone, processingmeans (4) for processing said spatial signal by applying again not exceeding a resulting maximum gain limit to form ahearing loss compensation signal, wherein the resultingmaximum gain limit is derived from the first and secondacoustic feedback signals and the mixing ratio, and anoutput transducer (3) for converting the hearing losscompensation signal into an acoustic output. The inventionfurther provides a method and a computer program product.
