A new study shows that music teachers are routinely exposed to noise levels that could result in hearing loss. Researcher Hans Kunov says, “The hair cells of the inner ear simply crumble under the load, and they don’t grow back again.”
According to Canadian law, noise levels on the job should not exceed 90 decibels, which is the equivalent of a power lawn mower being run over eight hours in a 24-hour period.
Researcher Willy Wong measured the noise exposure of 18 music teachers at 15 high schools in Toronto and found that the peak noise level exceeded 85 decibels for 78% of them. During an average eight-hour day, 39% of them experienced harmful noise levels.
