Abstract: An auditory device includes an electronics module, a receiver and a cable connecting the electronics module to the receiver. The electronics module includes an enclosure shaped to be positioned behind an outer portion of either a left ear or a right ear of a user and circuitry within the enclosure. The receiver is configured for being located in either a left or a right ear canal of the user. When inserted into the left ear canal, the receiver occupies a left ear canal insertion position, and when inserted into the right ear canal, the receiver occupies a right ear canal insertion position. The cable and the receiver are shaped and configured such that the receiver is presented in a neutral position when no external force other than gravity is acting upon the receiver, the neutral position being between the left ear canal insertion position and the right ear canal insertion position.

Abstract: A method of forming custom shaped injection molded parts from elastomeric materials includes using a rapid prototyping system to create a rigid, hollow, mold. The mold has a relatively thin, breakable, side wall. Elastomeric material can be injected into the mold and cured. The mold can then be broken to extract a cured elastomeric part.

Abstract: A communication system, such as a hearing aid or a public address system, may include a microphone for inputting audio information to the system, an amplifier for amplifying audio frequency signals inputted to the microphone, and a speaker for outputting amplified audio frequency signals into the environment which provides an acoustic feedback path between the speaker and the microphone. The invention provides an identification circuit for dynamically identifying those parameters associated only with acoustic feedback, and a correction circuit whose transfer function is established in accordance with the parameters identified by the identification circuit. The transfer function of the correction circuit is such that the effect of acoustic feedback is cancelled from the transfer function of communication system. The identification circuit is constructed and arranged to identify said parameters in response to a turn-on of the system, or to an automatically-sensed threshold change in gain of the amplifier.
