Adjusting noise reduction in headphones
First Claim
1. A headset comprising:
- first and second earcups each having a front opening adapted to be adjacent to a respective ear of a user and comprising an electroacoustic transducer;
a headband coupled to each of the earcups; and
an active noise reduction circuit coupled to the electroacoustic transducers;
whereinthe headband is configurable between at least two on-head configurations that each press the earcups against the head of the user with different amounts of force without continued application of external force; and
the active noise reduction circuit is configuredto determine which of the at least two on-head configurations the headband is configured in based on signals received from a microphone,to provide a different amount of active noise reduction when the headband is configured in each of the different amounts of force, andto automatically transition between the different amounts of active noise reduction in response to a change in the configuration of the headband between the at least two configurations.

Abstract
A headset includes first and second earcups each having a front opening adapted to be adjacent to a respective ear of a user and including an electroacoustic transducer, a headband coupled to each of the earcups, and an active noise reduction circuit coupled to the electroacoustic transducers. The headband is configurable between at least two configurations that each press the earcups against the head of the user with different amounts of force. The active noise reduction circuit is configured to determine which of the at least two configurations the headband may be configured in, to provide a different amount of noise reduction when the headband may be configured in each of the different amounts of force, and to automatically transition between the different amounts of noise reduction in response to a change in the configuration of the headband between the at least two configurations.
