SYSTEMS AND METHODS FOR ADAPTIVE NOISE CANCELLATION BY BIASING ANTI-NOISE LEVEL

A processing circuit may comprise an adaptive filter having a response generating an antinoise signal from a reference microphone signal, a secondary path estimate filter modeling an electroacoustic path of a source audio signal, a biasing portion that generates a scaled antinoise signal by applying...
