Abstract

Apparatus and method of controlling provision of ANR, possibly of a personal ANR device, in which amplitudes of a piece of audio employed in the provision of ANR are monitored, and the compression of one or both of feedback and feedforward ANR reference sounds is made dependent on frequency such that a first sound of one frequency need only reach a lower amplitude to trigger compression, while a second sound of another frequency must reach a higher amplitude to trigger compression.
