subject: Ear Protection Prevents Fatal Damages [print this page] Noise-Induced Hearing Loss, or NIHL, is a serious matter, and not simply a matter of time (length and/or frequency of exposure) but intensity as well (how loud the sound is). What it is, is when the sound, or traveling air pressure - which is what sound is, physically - is just too great for our delicate ear structures, overstimulating them and causing damage as a result. OSHA takes NIHL seriously, and so should you! Moreover, it is important to note that OSHA standards provide only for minimal safety, and individual requirements can call for levels well below what OSHA stipulates.
