Electronic earplug for providing communication and protection

摘要

Systems and methods for providing communication and protection by an electronic earplug are provided. A communication and protection system includes an electronic earplug operable in a transmit mode and a receive mode. The electronic earplug includes an external microphone, an ear canal microphone, processing circuitry, and a receiver. In the receive mode, the external microphone is configured to transduce sound pressure levels received from exterior to an ear canal to electrical signals; the processing circuitry is configured to process the electrical signals from the external microphone to provide processed electrical signals; and, the receiver is configured to convert the processed electrical signal to sound. In the transmit mode, the ear canal microphone is configured to transduce sound pressure levels received from in the ear canal to electrical signals provided to a communication device; and, one or more of the external microphone, the processing circuitry, and the receiver is disabled.
