Calibration of a remote-control unit for use in acoustic remote control

A remote-control unit for controlling a hearing assistive device by sending a control signal with instructions as an acoustic signal, the remote-control unit having a processor, an input transducer an output transducer, and a memory, wherein the processor is adapted for controlling a calibration process by:

• outputting tones via the output transducer,
• receiving tones via the input transducer,
• comparing tone level of the received tone relatively to a reference,
• adjusting relative volumes of the tones applied by the control signal in dependence of the comparison, and
• storing in the memory the adjusted relative volumes of the tones for use when sending a control signal with instructions as acoustic signals.
