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.”
