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, the
Consumer Electronics Association (CEA)® and the
American Speech-Language-Hearing Association (ASHA)
want you to get the most out of your equipment by playing it
at a safe level; a level that lets the sound come through
clearly without annoying blaring or distortion and, most
importantly, without damaging 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:
Set your volume control to the lowest level where you can
hear the music comfortably and clearly. Prolonged
exposure to anything over 85 decibels can cause gradual
Once you have established a sound level where you can
hear the audio comfortably, clearly and without distortion,
set the dial and leave it there.
See if your music player has a volume limiter that allows
you to set a safe listening level by establishing a maximum
volume level on your player. This is a great solution for
parents to ensure their children listen at a safe level.
Limit listening time to give your hearing “quiet breaks.”
BE SURE TO OBSERVE THE FOLLOWING GUIDELINES
WHEN WEARING YOUR HEADPHONES OR EARBUDS:
Do not turn up the volume so high that you can’t hear
sounds around you.
Do not use headphones or earbuds while operating a
motorized vehicle; it may create a traffic hazard and is
illegal in many areas.
Used wisely, your new sound equipment will provide
years of fun and enjoyment. Since hearing damage from
loud noise is often undetectable until it is too late, this
manufacturer, CEA and ASHA recommend that you avoid
prolonged exposure to excessive noise. The following list of
sound levels is included for your information so that you
can better protect your hearing.
DECIBEL LEVEL EXAMPLES:
40 Quiet room
50 Moderate rainfall
60 Normal conversation
70 Busy traffic, vacuum cleaner
80 Alarm clock
CONSTANT EXPOSURE TO THESE NOISES CAN BE
90 Lawn mower, motorcycle
100 Chain saw
110 Rock concert
120 Jet plane takeoff
