DEPENDS: dB X length
N.I.H.L. (noice induced hearing loss
) is due
to long or repeated exposure to sounds at or above 85 decibels .
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.
Nihl is 100 percent preventable! all individuals should understand the hazards of loud noise. & please protect hearing!
