Abstract
An open ear canal hearing aid system is disclosed which comprises a plurality of ear canal tubes 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. The open ear canal hearing aid system further comprises a sound processor for amplifying ambient sounds received through one of the ear canal tubes within a predetermined frequency range and to produce processed sounds and for supplying the processed sounds to the second ear canal tube. According to other embodiments of the present invention, the speaker and/or microphone can be located in the ear canal at the end of the ear canal tubes. In these embodiments, the speaker and/or microphone are electrically connected to the sound processor by wires in the ear canal tubes.
