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,

hearing.
