4 basic Hearing
Systems Comparisons and Information
|
Here's a very brief introduction into 4 basic types of
hearing assistance systems: The FM, sound field, infrared, and room
loop systems.
FM System. For hearing assistance, sound
from the FM transmitter travels in invisible waves on specific channel frequencies that
the FCC has designated for this purpose and is picked up by compatible receivers.
Small portable FM systems are
available for classes, workshops, tours and language translations. FM can be used indoors, outdoors, day or night, allowing for the most
versatility and freedom. May be use in combination with other systems.
Anyone with a mild to severe hearing loss
can benefit using these receivers with the quality ear accessories that are available.
Receivers allow for personal control of volume comfort levels. The
transmitter can connect to existing sound systems.
Sound
Field System. Sound through a room speaker or portable
speaker. Benefits many people at once over an entire area. Look for good sound
quality for clarity rather than volume increase alone for people to hear better. Be
aware of reverberation increasing background noise.
Infrared
System. Infrared is a beam
of light that sound from the transmitter
travels in invisible light waves on frequencies that the FCC has designated for this
purpose and is picked up by compatible infrared receivers.
Infrared is generally preferred for darkened theatres, also useful where privacy is
important such as the court jury rooms. This system must be installed by a professional.
Room Loop
System. A room loop system is a wire looped around an area that
is connected to the loop system. The transmitter transmits sound through this wire
electromagnetically to the hard of hearing person's tele-coil (T-coil) in their hearing
aid. Persons must have a tele-coil (T-coil) in their hearing aid to use this system
or use an induction receiver. For various reasons not everyone has a hearing aid with a
tele-coil.
Is everyone in the audience hearing
your important message? If you're not being heard, what's
the point in talking.
You may already know that distance
from the speaker, poor acoustics and background
noise can create a challenging listening environment even for people that
can hear well. Did you also know it's estimated 10% of the population experiences hearing
loss of varying degrees. This is a significant number of people that are being left out of
a great deal of verbal information. And, unfortunately, this problem is invisible.
To solve this, many places are installing
"hearing assistance " to assist, attract, and keep people
that are experiencing hearing difficulty. I've seen good people loose interest, begin to
withdraw, and eventually stop participating, simply because they couldn't hear well. After
all, as an example; how long would you sit in front of a TV with the sound down. But then,
I've also seen their eyes brighten, and become interested in participating again with the
help of simple hearing assistance.
