Listening for a lifetime

Selecting fine audio equipment such as the unit youʼve just purchased is only the start of your

musical enjoyment. Now itʼs time to consider how you can maximize the fun and excitement your

equipment offers. VocoPro and the Electronic Industries Associationʼs 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 can 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 Associationʼs Consumer Electronics Group recommend you avoid

prolonged exposure to excessive noise. This list of sound levels is included for your protection.

Quiet library, Soft whispers

Living room, Refrigerator, Bedroom away from traffic
