Abstract
The present disclosure relates to methods and apparatus of communicating instructions to a hearing assistance device, such as a hearing aid. In various embodiments instructions are formed using tones sent to the hearing assistance device. The instructions can be used to control the operation of the hearing assistance device. The signals may include dual tone multifunction signals or other nonstandard signals. Various detection processes are provided which include but are not limited to using a modified complex Goertzel algorithm to detect tones. The remote device can be a standard device or can be modified to provide the proper signals. The following techniques can be applied to hearing assistance devices including, but not limited to completely-in-the-canal devices, in-the-canal devices, behind-the-ear devices, receiver-in-canal devices, and implanted devices, such as cochlear implants.
