Patent abstract
An earpiece may be used to detect sounds from an ear canal of a user. The earpiece may include a microphone assembly and an acoustic pathway that is at least partially defined by a hollow elongated member. The acoustic pathway fluidly couples the microphone assembly with an ear canal of the user when the earpiece is positioned with respect to the ear of the user. Sounds produced by the user travel from the ear canal through the acoustic pathway for detection by the microphone assembly. Also, the hollow elongated member behaves as an acoustic waveguide to amplify a desired frequency and/or attenuate other, less desirable, frequencies of the sounds produced by the user.
