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

80 Alarm clock

CONSTANT EXPOSURE TO THESE NOISES CAN BE

DANGEROUS:

90 Lawn mower, motorcycle

100 Chain saw

110 Rock concert

120 Jet plane takeoff

130 Jackhammer

140 Firecrackers
