Abstract: A hearing assistive system, comprises a personal communication device (10) and a head-worn device (20). The personal communication device (10) has a user interface (12) being adapted for user interaction, a processor (11) controlling the user interface (12) and being adapted to run an application program, a short-range radio (13), and an output transducer (15). The head-worn device (20) has an input transducer (24) adapted for converting sound into an electric signal applied to a processor (21) outputting a modified audio signal via an output transducer (25). The application program is adapted to generate and output a data packet (70) on an audio carrier via the output transducer (15). The head-worn device (20) has an audio signaling block (26) for detecting and decoding the data packet (70) received by the input transducer (24). The head-worn device (20) has a controller (27) for controlling the operation of a short-range radio (28). The audio signaling block (26) is adapted to detect a radio pair command included in the data packet (70), and to instruct the controller (27) to enter pairing mode for the short-range radio (28), accordingly.

Abstract: A remote-control unit (10) is adapted for sending a control signal with instructions as an acoustic signal for controlling a hearing assistive device (20). A calibration method comprises outputting tone frequencies applied by the control signal, receiving the output tone frequencies and compare tone frequency levels relatively to a reference, adjusting relative volumes of the tone frequencies applied by the control signal in dependence of the comparison, and storing the adjusted relative volumes of the tone frequencies for use when sending a control signal with instructions as acoustic signals.
