Title: COMMUNICATION CHANNELS BETWEEN A PERSONAL COMMUNICATION DEVICE AND AT LEAST ONE HEAD-WORN DEVICE
Abstract:
A hearing assistive system, comprises a personal communication device (10) and a headworn 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 (19a), an input transducer (14) 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 (19a) is adapted to generate a data packet (70) modulated on an audio carrier and output via the output transducer (15), and to decode a data packet (70) modulated on an audio carrier and received via the output transducer (15). The head-worn device (20) has an audio signaling block (26) having a detector block (31-34) and a response block (35-36). The detector block (31-34) is adapted to detect and decode the data packet (70) received by the input transducer (24). The response block (35-36) is adapted to generate a data packet (70) modulated on an audio carrier and output via the output transducer (25).
