Abstract
A communications earpiece comprises an ear canal tube sized for positioning in an ear canal of a user so that the ear canal is at least partially open for directly receiving ambient sounds. A microphone port in the ear canal tube is located in the ear canal for detecting sounds in the ear canal. A speaker port in the ear canal tube is located in the ear canal in close proximity to the microphone port for broadcasting sound signals into the ear canal. A sound processor amplifies the ambient sounds received by the microphone to produce processed analog signals. The sound processor also comprises noise cancellation means for producing an inverse noise signal of noise detected in the ear canal by the microphone. The inverse noise signal is sent to the speaker port so as to be broadcast into the ear canal thereby substantially canceling the ambient noise in the ear canal.
