摘要： A speech intelligibility system. Embodiments comprise a talker unit, a listener unit and an earpiece. The talker unit includes a microphone to receive audible speech content and to produce electrical signals representative of the speech content, and a transmitter coupled to the microphone to produce wireless transmissions containing the speech content. The listener unit includes a receiver to receive the wireless transmissions and to produce electrical signals representative of the speech content. At least one of the talker unit and the listener unit includes an amplifier to amplify spectral components of the speech content within a frequency range having a lower end between about 800 Hz and 1,700 Hz and an upper end between about 7,000 Hz and 11,000 Hz. The earpiece is coupled to the listener unit and includes a speaker to produce audible speech content having the amplified spectral components and a tube to direct the audible speech content from the speaker toward a user's ear canal.

摘要： A system and/or method is provided for enhanced listening of audio signals acquired via a telecoil by performing hum filtering. The system may include a telecoil and a telecoil hum filter. The telecoil hum filter may include a comb notch filter. The comb notch filter may include a delay module and a comb notch filter summing module. The telecoil may be operable to receive a magnetic signal and convert the magnetic signal to an input audio signal. The delay module of the comb notch filter may be configured to generate a delayed signal by applying a delay to the input audio signal. The delay may be based on a fundamental hum frequency. The comb notch filter summing module may be configured to generate a comb notch filter output signal by adding the input audio signal and the delay signal.

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.
