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.

・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.

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.”

・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.

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

80 Alarm clock

90 Lawn mower, motorcycle
100 Chain saw

110 Rock concert
120 Jet plane takeoff
130 Jackhammer
140 Firecrackers
