Abstract
Data is transferred to and from a hearing aid by transmitting an audible carrier having a frequency greater than 5 kilohertz, modulating the carrier with data, and detecting the modulated carrier in the hearing aid with a narrow band filter. The frequency is in a region where impairment occurs and there are many other sounds, thereby masking the communication, yet not interfering with it.
