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 Level (dB)
Refrigerator humming 40
Normal conversation 60
City traffic 80
Motorcycles and lawnmowers 90 #
Rock concerts 110-120 #
* 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 with extended exposure.

For your safety!
Your hearing may adapt to higher volumes of sound. In order to prevent any harmful impact
to your hearing, you must control the sound emanating from your headphones and set the
MP3 player volume to a low setting where you can hear it clearly and comfortably.
Studies, including one from NIDCD indicate that sounds of less than 80 decibels, even after
long exposure, are unlikely to cause a hearing loss. Listen to your MP3 player at such a level
that you can still hear conversation and other people in your environment without shouting
when you attempt to converse.
It can also be dangerous to play your music with headphones/earphones at high volume
while walking or engaged in other activities. You should exercise extreme caution and
discontinue use in potentially hazardous situations.
Do not use headphones/earphones while driving, cycling, or operating any motorized
vehicle. This may create a traffic hazard and may be illegal in some areas.
