Abstract
The present invention regards a binaural hearing system comprising a first hearing device and a second hearing device. Each of the hearing devices comprises a power source, an environment sound input, a link unit and electric circuitry. The environment sound input is configured to receive sound from an acoustic environment and to generate an environment sound signal. The link unit is configured to transmit the environment sound signal from the hearing device comprising the link unit to a link unit of the other hearing device of the binaural hearing system and to receive a transmitted environment sound signal from the other hearing device. The electric circuitry of each of the hearing devices is configured to process and environment sound signals and transmitted environment sound signals and to estimate a respective time delay between the environment sound signal and the transmitted environment sound signal based on the corresponding processed signals. The electric circuitry is configured to apply the respective time delay to the transmitted environment sound signal to generate a time delayed transmitted environment sound signal. The electric circuitry is configured to subtract the equalized (at least time delayed) transmitted environment sound signal from the environment sound signal to receive an equalized-cancelled environment sound signal, and to determine a target signal and/or a noise signal based thereon.
