Listening for a Lifetime
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. VocoPro 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 a
higher volume 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 hear it comfortably and clearly,
and without distortion.
Once you have established a comfortable sound level:
• Set the dial and leave it there.
• Pay attention to the different levels in various recordings.
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.
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.
