<p>Wireless binaural hearing system A wireless binaural hearing system (1) comprises a left-ear hearing device (L), a right-ear hearing device (R) and a number of auxiliary devices (S, B). The devices (L, R, S, B) communicate with each other via radio signals. Thus, 5 each device (L, R, S, B) comprises a radio transmitter (15) for transmitting messages, each hearing device (L, R) comprises a radio receiver (16) for receiving messages, the auxiliary device (S, B) is adapted to transmit application messages (S1-S4), and the hearing devices (L, R) are adapted to receive application messages (S1-S4). The quality of the wireless 10 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, 15 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 20 efficient physical communication paths between a sender (S) and a receiver (R). (FIG 3 shall be published with the abstract.) L, R 22-04-2010 11:01:20</p> |
