A system for providing a talk-over functionality from an attendant to a hearing aid user comprises a hearing aid ( 4 ), a link device ( 5 ) connected to the hearing aid ( 4 ), a computer ( 7 ) with a talk-over microphone ( 9 ), and a communications link ( 6 ) linking the computer ( 7 ) to the link device ( 5 ), the hearing aid user, the hearing aid ( 4 ), and the link device ( 5 ) being positioned in a sound-proof box ( 1 ). The computer ( 7 ) is adapted for receiving signals from the microphone ( 9 ), and for executing audio processing software for processing the microphone signals for converting them into compressed, digital audio signals and transmitting these signals via the communications link ( 6 ) to the link device ( 5 ). The link device ( 5 ) is adapted for decompressing the received signals and converting them into audio signals to be served to the hearing aid ( 4 ) in real-time. The system enables an attendant or a hearing aid fitter to talk to a hearing aid user via the communications link ( 6 ). This may, for instance, be useful when the hearing aid user is acoustically isolated from the fitter during fitting of the hearing aid ( 4 ). The invention provides a system and a method for providing a talk-over functionality.
