Abstract:
A hearing aid includes an ambient microphone configured to receive and convert environmental sound into an electronic input signal, a hearing loss processor configured to process the electronic input signal in accordance with a hearing loss of a user, and generate an electronic output signal, a receiver, an ear canal microphone configured for converting ear canal sound pressure into an ear canal signal, an occlusion suppressor for reception and processing of the ear canal signal and for transmitting an occlusion suppression signal, and a signal combiner configured for combining the occlusion suppression signal and the electronic output signal to form a combined signal, and for transmitting the combined signal to the receiver, wherein the receiver is configured to receive the combined signal, and convert the combined signal into an acoustic output signal, and wherein the receiver has a frequency response with a lower cut-off frequency that is less than 40 Hz.
