WIRELESS BINAURAL HEARING DEVICE

A wireless binaural hearing system (1) comprising a left-ear hearing device (L), and a right-ear hearing device (R), each device (L, R) comprising a radio transmitter (15) for transmitting messages, each hearing device (L, R) comprising a radio receiver (16) for receiving messages, each of the hearing devices (L, R) being adapted to receive application messages (S1-S4) from an auxiliary device, and to transmit acknowledgement and/or non-acknowledgement messages (A, N) indicating respectively whether application messages (S1-S4) were correctly received or not, a first one of the hearing devices (L) being adapted to transmit and thus relay received application messages (S2, S4), a second one of the hearing devices (R) being adapted to receive relayed application messages (S2L, S4L), characterised in that the first hearing device (L) is adapted to relay received application messages (S2, S4) in dependence on not receiving acknowledgement messages (A) transmitted by the second hearing device (R) and/or on receiving non-acknowledgement messages (N) transmitted by the second hearing device (R). The quality of the wireless communication varies when the user moves his head, which may lead to temporal gaps in the communication. Such gaps may cause annoying pauses and/or delays in audio signals presented to the user, and the hearing devices (L, R) may become temporarily unsynchronised. The invention aims at avoiding such gaps in order to improve the reliability of the communication, however without increasing the radio signal power. This is achieved by letting a first hearing device (L) relay received application messages (S2, S4) to a second hearing device (R) in dependence on network messages (A, N) received from the second hearing device (R) indicating whether application messages (S1-S4) were correctly received. This allows for having several efficient physical communication paths between a sender (S) and a receiver (R).
