Abstract

Noise cancellation operations consume battery power, and thus techniques for reducing power consumption by performing power management in active noise cancellation in consumer devices are beneficial for the user. One example power management technique described according to embodiments of this disclosure allow wind noise detection to switch between a high-power higher-accuracy operation and a low-power lower-accuracy operation. For example, multiple microphones may be available on the personal device for detecting wind noise, in which using multiple microphones increases accuracy but also increases battery consumption. A personal device may switch between using a single microphone and multiple microphones based on environmental conditions to provide improved performance in certain environmental conditions and reduced power consumption in other environmental conditions.
