<p>A new hearing aid is provided with improved preservation of spatial cues of an incoming sound signal, the hearing aid comprising
a BTE hearing aid housing to be worn behind the pinna of a user,
at least one BTE sound input transducer for conversion of acoustic sound into an audio sound signal,
a processor configured to generate a hearing loss compensated output signal based on the audio sound signal,
a sound signal transmission member for transmission of a sound signal from a sound output in the BTE hearing aid housing at a first end of the sound signal transmission member to the ear canal of the user at a second end of the sound signal transmission member,
an earpiece configured to be inserted in the ear canal of the user for fastening and retaining the sound signal transmission member in its intended position in the ear canal of the user, and
an output transducer for conversion of the hearing loss compensated output signal to an auditory output signal that can be received by the human auditory system,
an ITE microphone housing accommodating at least one ITE microphone and configured to be positioned in the outer ear of the user for fastening and retaining the at least one ITE microphone in its intended position, and further comprising at least one adaptive cue filter, each of which having
an input that is provided with an output signal from a respective one of the at least one BTE sound input transducer, and
the filter coefficients of which are adapted so that the difference between an output of the at least one ITE microphone and a combined output of the at least one adaptive cue filter is minimized.</p> |
