magnetic signal a lot better than the acoustic signal
from the sound processor’s microphone. In other
words, a telecoil acts as an alternate or supplemen-
tal input device to the microphone.
There are many ways to use a telecoil:
• With a telecoil-compatible phone.
• In movie theaters, sports stadiums, churches, and
lecture halls that have an induction loop system
or infrared system.
• With personal neck-loops, telecoil-compatible
headphones/headsets, Hatis
®
, or telecoil-
compatible telephone and cell phone.
Lapel microphone
Mak
e it easier for the child to hear in noisy
situations:
• The microphone allows the child to hear more
clearly in noisy environments. The microphone
should be clipped to the sound source
.
• The microphone can capture sounds coming
from multiple directions.
Many cochlear implant
users hear with only a single implant. The lapel
microphone picks up the sound coming from the
side without an implant. It can be connected to
the processor and placed in the center of a
table, for example. This enables the cochlear
implant user to hear the voices of everyone
around the tab
le and will reduce background
noise.
• The microphone can be connected to Nucleus
processors to check the quality of the
processor’s microphone. If the student reports
that the sound has improved with the lapel
microphone in place, the processor microphone
may be wet or damaged.
A lapel microphone is available for all currently
available Nucleus sound processors.
Other commercially available products
and accessories
Closed headphones have large hollow earpieces
that can be used to completely enclose the
cochlear implant microphone or BTE processor.
The padded cuff provides comfort over the implant
and reduces background noise.
In absence of a patch cable, closed head-
phones can be used successfully by
many cochlear implant users.
Personal neckloops work in
conjunction with telecoils. The
neckloop is placed around the neck and
has a 3.5mm plug that connects to the
audio component. When used with an
activated telecoil,
the neckloop deliv
er
s
the sound from the audio component
to the telecoil via magnetic induction.
