Abstract

A method and apparatus for automatically adjusting the volume of a headset (110) is described herein. The headset (110) includes a speaker (112) and a pressure transducer (114). The speaker (112) projects audible signals into the ear canal (14), while the pressure transducer (114) measures a sound pressure level in the ear canal (14). Based on the measured sound pressure level, a control system (130) controls the volume of the audible sound projected from the speaker (112).
