Patent ID: 8437812

Claim:
An automatic noise reduction (ANR) headset or headset assembly for use with an aircraft two-way radio and a mobile telephone, comprising: a pair of circumaural earcups connected by a headpiece; a speaker associated with at least one earcup; an ANR microphone associated with at least one earcup; a boom microphone extending from one of the earcups and coupled to a preamplifier; a battery connector for connecting a first power source having a first voltage level; a two-way aircraft radio input for connecting a second power source having a second voltage level different from the first voltage level; and control circuitry coupled to the speaker, the ANR microphone, the preamplifier, the battery connector, and the two-way aircraft radio input, wherein the control circuitry generates signals for the speaker to provide automatic noise reduction based on signals from the ANR microphone and selectively couples the preamplifier to receive power from the first power source or the second power source to enable use of the boom microphone with the mobile telephone, and wherein the control circuitry comprises a communications priority module that reduces amplitude of an audio signal from an auxiliary device coupled to the headset or headset assembly relative to amplitude of an audio signal from the aircraft two-way radio.
