Warning
Use your headphones responsibly. Exposure to excessively loud noise can cause
Noise Induced Hearing Loss (NIHL). “The loudness of sound is measured in units called
decibels. For example, the humming of a refrigerator is 40 decibels, normal conversation
is approximately 60 decibels, and city traffic noise can be 85 decibels. Sources of noise
that can cause NIHL include motorcycles, firecrackers, and small firearms, all emitting
sounds from 120 to 150 decibels. Long or repeated exposure to sounds at or above
85 decibels can cause hearing loss. The louder the sound, the shorter the time period
before NIHL can occur. Sounds of less than 75 decibels, even after long exposure, are
unlikely to cause hearing loss.”

Before plugging your Soul® headphones into your phone or multimedia device, make
sure that the volume has been set to zero (0) and the power is off. Once you have
turned on the device, increase the volume to a safe and comfortable level. Putting on
your headphones and turning on at full volume may cause damage to your hearing.
Keep headphones out of reach of small children. These headphones are not a toy and
could be harmful to small children.
Below is a chart to help you better understand the causes and effects of different
sound levels. The noise levels are rated in dB (decibels)
Environmental Noise Noise Level dB Possible Effects of Exposure
Quiet Library 30 dB No Effect - Normal
Normal Conversation 60 dB Comfortable Hearing
City Traffic (inside car) 85 dB Maximum Level before hearing
damage begins. OSHA recommends no
more than 8 hours of exposure to sound
levels of 90 dB daily.
Power Saw at 3’ 110 dB Permanent Hearing Loss likely due
to prolonged unprotected exposure.
Jet Engine at 100’ 120 to 140 dB At 125 dB the human ear begins to
experience pain that can lead to
permanent hearing loss even
during short unprotected periods.
