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. 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 hearing loss.
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:
30 Whisper
40 Quiet room
50 Moderate rainfall
60 Normal conversation
70 Busy traffic, vacuum cleaner
