Abstract
A method performed by a wearable audio output device worn by a user is provided for controlling the reproduction of external noise and/or noise masking. A first a first lower-power detector determines if the user is in transport or a change in the user's transport. In response to the determination, a second higher-power detector exits a power saving state and determines a mode of the transport based. The wearable audio output device adjust a level of attenuation applied by the wearable audio output device to the external noise or adjusting a level of noise masking output by the wearable audio output device based on the determined mode of the transport.

A method for controlling reproduction of external noise and audio output by a wearable audio output device worn by a user, comprising:
- detecting sound in the vicinity of the wearable audio output device using at least one microphone in the wearable audio output device;
- determining, by a first lower-power detector, the user is in transport based, at least in part, on the detected sound;
- in response to the determination, triggering a second higher-power detector to exit a power saving state and determine a mode of the transport based, at least in part, on the detected sound;
- and
- adjusting a level of attenuation applied by the wearable audio output device to the external noise or adjusting a level of noise masking output by the wearable audio output device based on the determined mode of the transport.
A method for controlling reproduction of external noise and audio output by a wearable audio output device worn by a user, comprising:
- detecting sound in the vicinity of the wearable audio output device using at least one microphone on the wearable audio output device;
- detecting a state of motion of the user using a sensor on the wearable audio output device;
- determining, by a first lower-power detector, the user is in transport based, at least in part, on a first portion of the detected sound and the state of motion of the user;
- in response to the determination, triggering a second higher-power detector to exit a power saving state and determine the user is in a first mode of the transport based, at least in part, on a second portion of the detected sound;
- and
- adjusting a level of attenuation applied by the wearable audio output device to the external noise or adjusting a level of noise masking output by the wearable audio output device based on the determined first mode of the transport.
