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.

Claim (Index 2):
The method according to  claim 1 , further comprising:\n at the first hearing aid, buffering a first frame of signal samples based on the sound signal picked up by the one or more input transducers; and at the second hearing aid, buffering a second frame of signal samples based on the sound signal picked up by the one or more input transducers, wherein transmission dependent on the determined transmission direction comprises\n transmitting the audio information from the first hearing aid to the second hearing aid comprising a) coding and transmitting the first frame from the first hearing aid to the second hearing aid, b) performing binaural processing of the second frame and a decoded received first frame at the second hearing aid, thereby providing a binaurally processed output signal from the second hearing aid and processing the first frame at the first hearing aid, thereby providing a processed output signal from the first hearing aid, and c) performing time alignment at the first hearing aid for synchronizing the output signals; or \n transmitting the audio information from the second hearing aid to the first hearing aid comprising a) coding and transmitting the second frame from the second hearing aid to the first hearing aid, b) performing binaural processing of the first frame and a decoded received second frame at the first hearing aid, thereby providing a binaurally processed output signal from the first hearing aid and processing the second frame at the second hearing aid, thereby providing a processed output signal from the second hearing aid, and c) performing time alignment at the second hearing aid for synchronizing the output signals, or \n no transmission of the audio information between the first hearing aid and the second hearing aid.
