Hearing Level Info
YOU MUST READ THIS BEFORE USING YOUR
SANSA MP3 PLAYER
Congratulations on the purchase of your Sansa
Your media player is equipped with a variety of features. To help you maximize your
listening pleasure, SanDisk would like to advise you that it is important to use your
headphones with your media player at a safe hearing level.
Exposure or repeated exposure for an extended period of time to music and other
sounds that are too loud can cause damage to your hearing resulting in temporary or
even permanent "noise induced hearing loss".
Symptoms of hearing loss increase gradually with prolonged exposure at high levels
of loudness. Initially, you may not even be aware of the loss unless detected with a
hearing test.
HEARING LEVELS
To help you understand what may be considered a safe hearing level, the following
examples are included for your reference.
Examples of Typical Approximate Sound level:
• Sound Levels in Decibels (dB)*
• Refrigerator humming 40
• Normal conversation 60
• City traffic 80
• Motorcycles and lawnmowers 90#
• Rock concerts 110-120#
• Firearms 120-140#
* A decibel (dB) is a unit of relative measurement of the strength of sound wave. In
decibels (dB), a measured signal level doubles with every additional 3 dB.
# These sound decibel levels are considered harmful under extended exposure.
