HEARING ASSISTANCE DEVICES WITH ECHO CANCELLATION
First Claim
1. A hearing instrument, comprising:
- a microphone;
a hearing instrument (HI) receiver;
a signal processor; and
an RF antenna, an RF receiver, and an RF transmitter;
wherein the hearing instrument is configured to operate in an acoustic mode and an RF mode;
wherein in the acoustic mode, the signal processor processes a signal representative of a sound detected by the microphone into a processed signal, and the HI receiver outputs an audio signal representative of the processed signal;
wherein in the RF mode, the RF transmitter transmits, using the antenna, a signal representative of a sound detected by the microphone, the signal processor processes a signal representative of a signal received by the RF receiver using the antenna, and the HI receiver outputs an audio signal representative of the processed signal.

Abstract
According to various embodiment of a method of operating a hearing instrument, an acoustic signal pathway is provided from a microphone through a signal processor to a hearing instrument (HI) receiver in an acoustic mode of operation. An RF transmit signal pathway is provided from the microphone to an RF transmitter, and an RF receive signal pathway is provided from the RF receiver through the signal processor to the HI receiver in an RF mode of operation. An input signal representative of sound detected by the microphone is adaptively filtered. A first adaptation rate is used for the acoustic mode of operation and a second adaptation rate is used for the RF mode of operation. The second adaptation rate is faster than the first adaptation rate.
