Abstract: An apparatus includes at least one housing configured to be implanted within a body of a recipient, at least one acoustic transducer positioned on or within the at least one housing, at least one motion sensor positioned on or within the at least one housing, gain circuitry configured to apply a gain to transducer output signals from the at least one acoustic transducer, at least one storage device, and at least one processor operatively coupled to the at least one acoustic transducer, the at least one motion sensor, the gain circuitry, and the at least one storage device. The at least one processor is configured to adjust the gain circuitry in response to a reference acoustic sensitivity function, a reference vibration response function, the transducer output signals, and sensor output signals from the at least one motion sensor.

Abstract: Embodiments presented herein are generally directed to techniques that provide a medical device component with the ability to communicate in both the near-field and far-field via a single antenna arrangement. More specifically, a medical device component includes an electronics circuit, a coil driver, an antenna arrangement, and an isolation circuit. The isolation circuit operates to extract far-field signals received at the antenna arrangement and provide these signals to the electronics circuit. The electronics circuit is protected from near-field signals received at the antenna arrangement via the isolation circuit.

Abstract: A microphone system including a first sensor configured to output a first signal based on an ambient sound relative to a recipient of the system, a second sensor configured to output a second signal corresponding to a noise reference, and first signal processing circuitry configured to process the first signal based on the second signal and output a third signal based on the processed first signal, wherein the system is configured to limit a gain of the third signal based on the presence of impulsive energy in the second signal.
