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 a safe 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 a safe level BEFORE your hearing adapts.
To establish a safe level:
•
Start your volume control at a low setting.
•
Slowly increase the sound until you can hear it comfortably and clearly,
and without distortion.
Once you have established a comfortable sound level:
•
Set the dial and leave it there.
Taking a minute to do this now will help to prevent hearing damage or
loss in the future. After all, we want you listening for a lifetime.
We Want You Listening For A Lifetime
Used wisely, your new sound equipment will provide a lifetime of fun
and enjoyment. Since hearing damage from loud noise is often undetectable
until it is too late, this manufacturer and the Electronic Industries
Association’s Consumer Electronics Group recommend you avoid
prolonged exposure to excessive noise. This list of sound levels is included
for your protection.
