Abstract
A hearing aid comprises a microphone configured to receive an acoustic input signal and convert the signal into an electric input signal, an audiological signal processing unit coupled to the microphone and configured to process the electric input signal to a processed signal, an amplifier coupled to the audiological signal processing unit and configured to amplify the processed signal to an amplified signal, and a receiver coupled to the amplifier and configured to transform the amplified signal into an acoustic output signal. The hearing aid further comprises a howl detector coupled to the signal processing unit and configured to detect the presence of a feedback howl originating from the hearing aid an analyzer coupled to the howl detector and configured to determine a value indicative of whether the feedback howl detected is potentially audible to a person neighboring the user of the hearing aid.
