Abstract: The disclosure relates to binaural hearing instruments and more particularly to reduction of processing time required in a binaural hearing aid system. According to the disclosure, there is provided a method comprising mono-directional transmission of data blocks comprising audio and/or information frames from one hearing instrument to the other hearing instrument or vice versa in a binaural hearing aid. According to the disclosure, the direction of transmission is determined by a quantity characterizing the presence of usable information content in the sound signal picked up by the hearing instruments of the binaural hearing aid. It is proposed to use one or more of local SNR, local voice activity detection indication, local level, local speech intelligibility estimate to determine the direction of transmission, although other quantities may be used.

Abstract: An intrusive binaural speech intelligibility predictor system receives a target signal comprising speech in left and right essentially noise-free and noisy and/or processed versions at left and right ears of a listener. The system comprises a) first, second, third and fourth input units for providing time-frequency representations of said left and right noise-free and noisy/processed versions of the target signal, respectively; b) first and second Equalization-Cancellation stages adapted to receive and relatively time shift and amplitude adjust the left and right noise-free and noisy/processed versions, respectively, and to provide resulting noise-free and noisy/processed signals, respectively; and c) a monaural speech intelligibility predictor unit for providing final binaural speech intelligibility predictor value SI-Measure based on said resulting noise-free and noisy/processed signals. The Equalization-Cancellation stages are adapted to optimize the SI-Measure to indicate a maximum intelligibility of said noisy/processed versions of the target signal by said listener. The invention may e.g. be used in development systems for hearing aids.

Abstract: A hearing device comprises a feedback-path estimation unit, which adaptively estimates a feedback path from an output transducer to an input transducer, and sets an adaptation-step size of an adaptive feedback-path estimation algorithm in dependence on an estimate of a background-noise spectrum. The feedback-path estimation unit provides an estimation-control signal for generating an acoustic feedback-path estimation signal having an level spectrum, which has at least one first frequency band with non-zero level and at least one second frequency band with zero level or with a non-zero level smaller than the level in the first frequency band and smaller than a background-noise level in the respective second frequency band. Background noise is detected in the second frequency band while the feedback-path estimation signal is provided. The background-noise level in the at least one first frequency band is estimated for obtaining the estimate of the background-noise spectrum. A corresponding method is described. The method is e.g. useful for estimating a feedback path during fitting of a hearing device, e.g. a hearing aid, to a particular user's needs.
