A method is provided for programming a digital hearing aid using a program encoded in an audio band (20 Hz - 20 kHz) signal, to transmit and verify programs and algorithm parameters. Preferably, this is in a digital hearing aid including filterbanks, filtering the audio signal into different frequency bands. The signal is encoded by the presence and absence of a signal in each frequency band or by other well-known modulation techniques used by computer modems. Special programming signals are provided alternating between the frequency bands in a manner to clearly distinguish the program data from any other interfering or normally present audio signal. The method does not require additional hardware, and offers reduced power consumption, as compared to some known wireless programming interfaces. It enables remote programming over a network using standard multimedia computer hardware. |
