摘要
The invention relates to a hearing aid system comprising first and second spatially separated hearing instruments, the system being adapted for processing input sounds to output sounds according to a user's needs. The invention further relates to a method and use. The object of the present invention is to provide an alternative scheme for reducing the effect of acoustic feedback in a hearing aid system. The problem is solved in that the hearing instruments comprises, respectively, first and second input transducers for converting a first input sound to first and second electric input signal, and first and second output transducers for converting first and second processed electric output signal to first and second output sounds, wherein the system is adapted to provide that a first Tx-signal originating from the first electric input signal of the first hearing instrument is transmitted to the second hearing instrument and used in the formation of the second processed electric output signal, and that a second Tx-signal originating from the second electric input signal of the second hearing instrument is transmitted to the first hearing instrument and used in the formation of the first processed electric output signal. This has the advantage of providing a scheme for reducing or effectively eliminating acoustic feedback in a pair of hearing instruments. The invention may e.g. be used in listening devices, e.g. hearing aids, head sets, or active ear plugs.
