    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 GOE, 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 GU, 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.

    Abstract: Aspects of the present disclosure provide multi-layer microphone protection for any apparatus that captures sound. The apparatus includes an enclosure defining a first cavity. A microphone element is coupled to the first cavity. The microphone element comprises a microphone sensor and a microphone cavity. A first, outer protective layer is disposed at an outer end of the first cavity, closer to the external environment. A second, inner protective layer is disposed between an inner end of the first cavity and the microphone element. The second, inner protective layer may protect the microphone sensor from particles or liquids that may have passed through the first protective layer. The first and second layers may have different acoustic properties.
