Abstract:
A communications system with noise cancellation, comprising:an ear tube section including at least one 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 operative communication with said ear tube section for detecting sound in said ear canal; a speaker port in operative communication with said ear tube section for broadcasting sound signals into said ear canal, the speaker port being operably connected to a speaker transducer positioned outside the ear canal; a sound processor for amplifying ambient sounds received by said microphone port to produce processed signals, the sound processor being located outside the ear canal; noise cancellation means for producing an inverse noise signal of noise detected in said ear canal by said microphone port; and means for sending said inverse noise signal to said speaker port to broadcast said inverse noise signal into said ear canal and to substantially cancel the ambient noise in the ear canal.
