Selecting fine audio equipment such as the unit
you've
just
purchased is only the start
of
your
musical enjoyment. Now it's time to consider how you can maximize the fun and excitement your
equipment offers. This manufacturer and the Electronic Industries Association's Consumer
Electronics Group want you to get the most out
of
your equipment by playing it at asafe level.
One
that lets the sound come through loud and clear without annoying blaring
or
distortion-and,
most
importantly, without affecting your sensitive hearing.
Sound can be deceiving.
Over
time your hearing "comfort level" adapts to higher volumes of
sound. So what sounds
"normal"
can actually be loud and harmful to your hearing. Guard against
this by setting your equipment at asafe level
BEFORE
your hearing adapts.
To
establish asafe level:
•Start your volume control at alow setting.
•Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.
Once you have established acomfortable sound level:
•Set the dial and leave it there.
Taking aminute to do this now will help to prevent hearing damage
or
loss
in
the future. After
all, we want you listening for alifetime.
We Want You Listening For ALifetime
