WIRELESS AVIATION HEADSET
First Claim
1. An aircraft wireless communication system comprising:
- a headset comprising;
left and right active noise reduction (ANR) microphones;
ANR circuitry coupled to the left and right ANR microphones that processes signals from the ANR microphones to generate corresponding driver signals in response to the signals from the ANR microphones;
left and right drivers coupled to the ANR circuitry that receive respective left and right driver signals;
a digital receiver coupled to the ANR circuitry;
a voice microphone; and
an analog transmitter coupled to the voice microphone;
andan aircraft panel interface comprising;
an analog receiver that receives wireless signals from the analog transmitter and provides corresponding signals to a wired output configured to connect to an aircraft panel; and
a digital transmitter connected to a wired input configured to connect to an aircraft panel and wirelessly transmit corresponding signals to the digital receiver.

Abstract
An aircraft wireless communication system includes a headset having an active noise reduction (ANR) microphone, ANR circuitry coupled to the ANR microphone that generates a driver signal in response to the signal from the ANR microphone, a driver coupled to the ANR circuitry that receives the driver signal, a digital receiver coupled to the ANR circuitry, a voice microphone, and an analog transmitter coupled to the voice microphone. The system also includes an aircraft panel interface having an analog receiver that receives wireless signals from the analog transmitter and provides corresponding signals to a wired output configured to connect to an aircraft panel, and a digital transmitter connected to a wired input configured to connect to an aircraft panel and wirelessly transmit corresponding signals to the digital receiver. The system may include a left-to-right cross-feed circuit for selected frequencies to improve speech intelligibility.
