Abstract: An hearing prosthesis configured to cancel received bone-conducted sound. The hearing prosthesis comprises: first and second matched microphones configured to be implanted in a recipient in a spaced arrangement such that the first microphone receives air-conducted sound signals and bone-conducted sound signals substantially simultaneously, and wherein the second microphone receives bone-conducted sound signals at substantially the same time as the first microphone and receives the air-conducted sound signals after a time delay. The time delay results in a relative phase difference between the air-conducted sound signals and the bone-conducted sound signals received by the second microphone. The prosthesis also comprises a noise cancellation system configured to cancel, based on the phase difference, the bone-conducted sound signals received by the first and second microphones.

Abstract: To improve processing of audio signals such audio signal is split (7) in two parts, one thereof being processed in time-domain (5) and at least the other part by frequency-domain processing (3). Thereby, the advantages of both processing domains are specifically exploited for respective parts of the signal to be processed.

Abstract: A method for frequency transposition in a communication device Or a hearing device, respectively, is disclosed by transforming an acoustical signal into an electrical signal (s) and by transforming the electrical signal from time domain into frequency domain to obtain a spectrum (S). A frequency transposition is being applied to the spectrum (S) in order to obtain a transposed spectrum (S?), whereby the frequency transposition is being defined by a nonlinear frequency transposition function. Thereby, it is possible to transpose lower frequencies almost linearly, while higher frequencies are transposed more strongly. As a result thereof, harmonic relationships are not distorted in the lower frequency range, and at the same time, higher frequencies can be moved to a lower frequency range, namely to an audible frequency range of the hearing impaired person.
