Abstract
A listening system includes one or more remote signal sources that generate one or more electronic signals, which correspond to sound in an ambient environment. A first ear microphone detects a first combination of audio signals including ambient sound and one or more propagated audio signals, corresponding to the one or more electronic signals, received at a first ear of a listener. The system includes first ear playback device and a processing device to apply a first set of audio filters including an audio filter to process a respective electronic signal of the one or more electronic signals with a first error signal, which is based on an output of the first ear microphone, to generate a first output signal to the first ear playback device, wherein acoustic cue components of the first output signal match corresponding acoustic cue components of the first combination of audio signals.
