Hearing enhancement system
First Claim
Patent Images
1. A hearing enhancement system for use by a first person in communicating with a second person, one of the persons having impaired hearing and using a hearing aid equipped with a selectively actuable inductive coupling (or T switch);
- the system comprising a microphone, an amplifier, a power supply, and an inductive loop, the inductive loop in use receiving amplified audio frequency signals from the-microphone so as to generate audio frequency inductive signals for receipt by the hearing aid inductive coupling;
at least the amplifier, power supply and inductive loop being connected together as a unitary article adapted to be readily worn on and removed from the body of one of the persons, and in which the inductive loop is a flexible elongate member which, in use, is worn around the body of said person; and
in which the inductive loop is provided with switching means by which the user may select a smaller or a larger number of turns to provide a range selection.

Abstract
A hearing enhancement system, for co-operation with a conventional hearing aid used in T-switch mode, comprises a microphone (10), an electronics module (22) including an amplifier and a power supply, and an induction loop (12). The induction loop (12) has a small number (typically 10-20) of conductor turns formed as a flexible assembly of a size suitable to be worn around the body as a sash or belt.
