Claim:
1. A method of controlling an audio system of an aircraft, comprising: storing a plurality of situation response models, each situation response model mapping expected cabin noise values to a respective set of values of a situation parameter that affects cabin noise values; determining a flight regime of the aircraft, wherein the flight regime comprises at least one of cruising mode, airplane mode, landing, take-off, hover, helicopter mode, ascent, descent, maximum power diving, or TOP climb; identifying, for the determined flight regime and in response to determining the flight regime, a flight regime situation response model mapping expected cabin noise values to the respective set of values of the situation parameter for the determined flight regime; identifying a weapon initiation situation response model that maps expected cabin noise levels attributable to a weapon initiation to the respective set of values of the situation parameter for the weapon initiation situation response model comprising an elapsed time after the weapon initiation; determining an expected cabin noise for a current value of (a) the situation parameter for the determined flight regime based on the flight regime situation response model and (b) the elapsed time after the weapon initiation based on the weapon initiation response model; selecting a volume level adjustment of the audio system to compensate for the determined expected cabin noise in the aircraft; and applying the selected volume level adjustment to the audio system, wherein a volume level of the audio system after applying the volume level adjustment is greater than zero volume.
