Abstract:
1. A hearing instrument configured to be worn on or in a wearer's ear, comprising: a microphone; a hearing instrument (HI) receiver; a signal processor; an RF antenna, an RF receiver, and an RF transmitter; an analog-to-digital (A/D) converter in communication with the microphone; a summer in communication with the A/D converter: an adaptive filter configured to deliver a filter output signal to the summer to subtract the filter output signal from a signal from the A/D converter; a mode specific adjuster in communication with the summer, the RF transmitter, the RF receiver, the signal processor, and the adaptive filter; and a digital-to-analog (D/A) converter in communication between the signal processor and the HI receiver, wherein the hearing instrument is configured to operate in an acoustic mode and a two-way 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; and wherein the mode specific adjuster is configured to provide an acoustic signal path from the summer to the signal processor in the acoustic mode, and provide an RF transmit signal path from the summer to the RF transmitter and provide an RF receive signal path from the RF receiver to the signal processor in the RF mode.
