Abstract: An integrated system for hearing protection and enhancement having earpieces including microphones and receivers to provide for user control of ambience level (mic gain), monitor input, control over limiting of excessive levels, and frequency equalization, all with very wide input dynamic range capability and controlled output dynamic range. The user control comprises a wired or wireless smartphone app. Also, the wide input dynamic range is achieved by placement of limiter circuitry capable of handling the entire input dynamic range prior to the most dynamic range limited circuit blocks: digital EQ block, output amplifier, earpiece receiver, and the users' ears. Switches allow combining left and right signals to be directed to a user's favored ear, if necessary.
