Abstract
Provided are a method and apparatus comprising an active noise reduction system. The active noise reduction system comprises an input transducer for transducing acoustic noise to a noise signal. The input transducer has a first sensitivity at a threshold temperature. The active noise reduction system includes circuitry that receives the noise signal and, in response, compensates for an effect by an ambient temperature on a second sensitivity of the input transducer by preventing the second sensitivity from being greater than the first sensitivity in response to a temperature deviation from the threshold temperature.
