Patent ID: 7519194

Claim:
A binaural hearing aid system comprising: first and second hearing aids adapted to be simultaneously worn at the head of a user for binaural amplification of an electrical signal; each of said first and second hearing aids comprising an input transducer that detects an acoustic input signal and converts said acoustic input signal into said electrical signal, a signal-processing unit supplied with said electrical signal that processes and frequency-dependent amplifies said electrical signal, dependent on selected parameters, to produce a processed electrical signal, an output transducer supplied with said processed electrical signal that converts said processed electrical signal into an output signal perceivable by the user as an acoustic signal, and a communication unit connected to the signal-processing unit, and a parameter setting arrangement in communication with the signal-processing unit allowing entry of said parameters into said signal-processing unit, said communication units in the respective first and second hearing aids communicating with each other to automatically communicate parameters that are set in one of said first and second hearing aids to the other of said first and second hearing aids; and at least said first hearing aid comprising an audio input allowing direct electrical supply of an audio input signal, from an audio signal source, to the signal processor in said first hearing aid, the signal processor in said first hearing aid then operating in an audio reception mode and limiting, to selected parameters, the parameters that are automatically communicated from said first hearing aid to said second hearing aid.
