We Want You Listening For A Lifetime
_mV.
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.
Selecting fine audio equipment such as the unit you've just
Decibel
purchased is only the start of your musical enjoyment. Now it' s time
Level
to consider how you can maximize the fun and excitement your
equipment offers. This manufacturer and the Electronic Industries
30
Association' s Consu met Electronics Group want you to get the most
40
out of your equipment by playing it at a safe level. One that lets the
50
sound come through loud and clear without annoying blaring or
60
distortion-and,
most importantly, without affecting your sensitive
70
hearing.
80
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. Alter all, we want you listening for a
lifetime.
