A group of Canadian researchers led by Alberto Bear (Alberto Behar) from the University of Toronto (U of T) has found that music teachers are often subject to high levels of noise so that they may lose hearing.

It turns out that the noise impact, which are in the middle of the day for music teachers — on the verge of allowable.

The consequence may be damage to the inner ear — the cells are destroyed his hair, which can not be restored.

Under Canadian labor law, the level of noise in the workplace should not exceed 90 decibels — the equivalent enabled lawn mower.

When the researchers measured the levels of noise experienced by 18 teachers from 15 schools of Toronto, they found that 78% of teachers to the peak level exceeds 85 decibels.

Thus, for an eight-hour working day 39% of the teachers seriously risk losing their hearing.

The problem is compounded by the fact that most of the classrooms have concrete walls, linoleum floors and beds made — because of the lack of sound-absorbing coatings teachers work too reflective sound environment.
