1. A noise compensation method, comprising:
receiving, by a control system and via an interface system, microphone signals corresponding to ambient noise from a noise source location in or near an audio environment;
determining or estimating, by the control system, a listener position in the audio environment;
estimating, by the control system, at least one critical distance, a critical distance being a distance from the noise source location at which directly propagated sound pressure of ambient noise from the noise source is equal to diffuse field sound pressure of ambient noise from the noise source;
estimating whether the listener position is within the at least one critical distance from the noise source location; and
implementing a noise compensation method for the ambient noise based, at least in part, on at least one estimate of whether the listener position is within the at least one critical distance from the noise source location.
