Adapting an audio response addresses perceptual effects of an interfering signal, such as of a residual ambient noise or other interference in an earpiece of a headphone. In one aspect, an input audio signal is presented substantially unmodified when it is at levels substantially above the interfering signal and is compressed when at or below the level of the interfering signal. The approach can make use of a measured level of an acoustic signal, for example, within an earpiece of a headset, and use the measured level in conjunction with the level of an input audio signal to determine compression characteristics without requiring separation of an interfering signal present in the monitored acoustic signal from a component related to the input audio signal. In another aspect, presentation characteristics of an input audio signal are determined to reduce distraction from an interfering signal, such as from a background conversation.
