  • Patent number: 9185499
    Abstract: A hearing aid includes: at least one microphone for provision of at least one microphone audio signal in response to sound received at the at least one microphone; a signal separation unit configured to provide an estimate of a target signal and an estimate of a masker signal based on the at least one microphone audio signal; a frequency modifying unit configured to modify a frequency content of at least one of the estimate of the target signal and the estimate of the masker signal, to thereby output the estimated target signal and the estimated masker signal substantially in different frequency bands; and a receiver for conversion of a combination of the estimate of the target signal and the estimate of the masker signal output by the frequency modifying unit into an acoustic signal for transmission towards an eardrum of a user of the hearing aid.

  • Patent number: 8638960
    Abstract: A BTE hearing aid includes a BTE hearing aid housing, at least one BTE sound input transducer, a processor configured to generate a hearing loss compensated output signal, a sound signal transmission member for transmission of a signal from a sound output of the BTE hearing aid housing to an ear canal of a user at a second end of the sound signal transmission member, an earpiece configured to be inserted in the ear canal, an output transducer, and an ITE microphone housing accommodating at least one ITE microphone, wherein the ITE microphone housing is configured to be positioned in an outer ear, wherein the processor is further configured for processing an audio signal from the at least one ITE microphone and an audio signal from the at least one BTE sound input transducer in such a way that the hearing loss compensated output signal substantially preserves spatial cues.
