International Symbol for Hearing Loss and
has an ear with a line drawn through it (to
signify hearing loss) and a capital “T” (to
signify telecoil) in the bottom right-hand
corner (Figure 7-7). More information
about the logo can be found on the Center
for Hearing Loss Help (http://www.hear-
ingloss help.com) and the Hearing Loop
(http://www.hearing loop.org) websites.
In the sections below, the application
of telecoils with a wide variety of induc-
tion methods is discussed. We begin our
discussion with induction loop systems
first as another wireless HAT (compare
to FM systems in Chapter 6 and infrared
systems in Chapter 8). From there, we
introduce additional devices and situa-
tions when telecoils and induction tech-
nology may also be beneficial.

Installation of induction loop systems
will depend on the purpose, location, and

receivers are available, additional instructions or a second
sign (or communication) will be required. Image courtesy
