Abstract
A hearing assistive system includes a personal communication device and a head-worn device. The personal communication device has a user interface for user interaction, a processor controlling the user interface and for running an application program, and input and output transducers. The head-worn device has an input transducer adapted for converting sound into an electric signal applied to a processor outputting a modified audio signal via an output transducer. The application program generates a data packet modulated on an audio carrier for output via the output transducer, decodes a data packet modulated on an audio carrier and received via the input transducer. The head-worn device has an audio signaling block having a detector block and a response block. The detector block detects and decodes the data packet received by the input transducer. The response block generates a data packet modulated on an audio carrier for output via the output transducer.
