Abstract
A device includes an ear occlude, an output transducer that is acoustically coupled to an ear canal of a wearer of the device, a voice microphone configured to generate a first electrical signal that is proportional to a voice-generated sound pressure at the microphone, and signal processing circuitry, electrically coupled to the output transducer and the microphone, including a compensator configured to generate, from the first electrical signal, a second electrical signal, and output the second electrical signal to the output transducer, wherein the compensator is tuned to cause GE, a ratio of a sound pressure within the ear canal to a voice-generated sound pressure at a mouth reference point when the ear is occluded and electronically-aided to be approximately equal to G, a ratio of the sound pressure within the ear canal to the voice-generated sound pressure at the mouth reference point when the ear is unoccluded.
