Continuous exposure to noise no louder than people shouting, over a period of years for 8 hours a day, 5 days a week can cause some degree of hearing loss

Sounds louder than 80 decibels are considered potentially dangerous. Both the amount of noise and the length of time of exposure determine the amount of damage. Hair cells of the inner ear and the hearing nerve can be damaged by an intense brief impulse, like an explosion, or by continuous and/or repeated exposure to noise.

HOW NOISE DAMAGES HEARING
Noise-induced hearing loss seldom involves total hearing loss or deafness. However, the damage cannot
be repaired and hearing aids can do little good. Constant exposure to noise affects the inner ear. The first
sign of hearing damage is an inability to hear higher pitched sounds; with continued exposure to noise, the
ability to tell musical tones apart becomes impossible. Eventually, with continual exposure to excess
noise, the ability to hear normal conversation is impaired.
opet sve ovo je povezano i sa jacinom zvuka, tako da ako zvucnike ne 'odvrces', mislim da nema cega da se plasis.
Ali sa obzirom da ovi tonovi spadaju u ultrazvuk, posto ih covek ne cuje lako se moze desiti da ne obrati paznju na jacinu tona koja lako moze preci dozvoljenu granicu.
