An apparatus includes a member configured to form an acoustic seal around a portion of an acoustic environment, and active noise reduction circuitry. The active noise reduction circuitry includes: detection circuitry configured to detect a change in pressure within the acoustic environment caused by movement of the member, and gain compensation circuitry configured to change a loop gain of a feedback loop in response to the detected change in pressure.
