ABSTRACT

A comprehensive review of the hearing aid telecoil would be incomplete without a discussion of induction loop assistive listening technology. Based on the classic scientific principles of alternating current and resultant electromagnetic fields, the applications for this technology continue to grow more than 60 years after the advent of the first telecoil-equipped portable hearing aid. In the following article, the authors present a technical primer and several scenarios that illustrate the basic principles and typical applications for induction loop assistive listening systems. They then provide a historical perspective and an overview of current standards and state of the art technologies. The authors conclude that the flexibility and performance of hearing aid telecoils will continue to evolve, along with induction-based assistive listening systems, as more hearing health care professionals demonstrate to their patients the potential of this useful technology.
