A method, system, and apparatus, for providing audio feedback regarding
the operation of an aircraft. In one aspect, microphones are placed next
to sound sources, which could be components of the aircraft. Audio inputs
are received from the microphone and analyzed based on a psycho-acoustic
model to provide settings, such as level, pan, and equalization, to an
automatic mixer. The automatic mixer mixes the sounds based on the
settings and provides audio output to the pilot of the aircraft. The
pilot can then use the audio output to more effectively monitor the
operations of the aircraft components, which might otherwise be difficult
or impossible to hear.
