Claims
- 1. An apparatus comprising:
a) a bus, the bus transmitting a bus signal, the bus signal comprising a plurality of audio signals from a plurality of audio devices; b) an audio processor, the audio processor coupled to the bus and receiving the bus signal, the audio processor determining if one of the plurality of audio signals is being transmitted on a transmitter, the audio processor preventing other of the plurality of audio signals from transmitting on the transmitter if one of the plurality of audio signals is being transmitted.
- 2. The apparatus of claim 1 wherein the audio processor receives a request-to-transmit signal from each of the plurality of audio devices seeking to transmit, and wherein the audio processor checks to determine if any other request-to-transmit signals are enabled to determine if one of the plurality of audio signals is being transmitted.
- 3. The apparatus of claim 1 wherein the audio processor prevents the other of the plurality of audio signals from transmitting by preventing the other of the plurality of audio signals from passing to the transmitter.
- 4. The apparatus of claim 1 wherein the audio processor further allows another of the plurality of audio signals to transmit when the one of the plurality of audio signals being transmitted ceases to be transmitted.
- 5. The apparatus of claim 1 wherein the plurality of audio devices comprises a plurality of audio devices designed to receive communication from crew members on an aircraft.
- 6. An apparatus comprising:
a) a bus, the bus transmitting a bus signal to a plurality of audio devices; b) an audio processor coupled to the bus, the audio processor receiving at least one warning signal, the audio processor converting said at least one warning signal to a digital signal and transmitting the converted at least one warning signal on the bus to the plurality of audio devices.
- 7. The apparatus of claim 6 wherein the at least one warning signal includes a ground proximity warning signal.
- 8. The apparatus of claim 6 wherein the at least one warning signal includes a collision avoidance warning signal.
- 9. The apparatus of claim 6 wherein the at least one warning signal includes a fire warning signal.
- 10. The apparatus of claim 6 wherein each of the plurality of audio devices includes a microphone input and a speaker output, and wherein the plurality of audio devices transmit communication signals on the bus to provide communication between crew members.
- 11. An apparatus comprising:
a) an audio volume sensing device, the audio volume sensing device determining an output volume for an aircraft audio communication device; b) a visual notification device, the visual notification device activated when the audio volume sensing device determines the output volume for the aircraft audio communication device is below a predetermined level.
- 12. The apparatus of claim 11 wherein the aircraft audio communication device includes a speaker output and a headset output, and wherein the audio volume sensor monitors the speaker output volume and the headset output volume.
- 13. The apparatus of claim 1I1 wherein the audio volume sensing determining when an output volume for an aircraft audio communication device determines when the audio communication device is off.
- 14. The apparatus of claim 11 wherein the visual notification device displays text indicating the output volume is below the predetermined level.
