Loop Sign
Sound is picked
up through the microphone, converted into magnetic
impulses by the amplifier and transmitted via the
loop aerial. This magnetic signal is, in turn, picked
up by the telecoil within hearing aids, and converted
back to speech.
To hear that speech
clearly, with little or no background noise, the user
only needs to switch his/her hearing aid to the “T”
(Telecoil) position.
InfoLoop Sound
Demonstration
IInfoLoop induction
loop systems significantly reduce background noise,
making communication easier and clearer. For hearing
aid wearers, an InfoLoop can make the vital difference
between hearing what is being said and feeling left
out.
Hearing aids have three
switch positions:
M The normal microphone
position. The hearing aid picks up all sounds and does
not distinguish between them.
TThe telecoil
position. This effectively switches the hearing aid
microphone off, so that the magnetic signals from induction
loops can be picked up, thereby reducing the amount
of background noise heard.
O The off position.
Switch between the M and T
positions on the hearing aid opposite to hear the difference
InfoLoop! makes.
