Their jobs are among the loudest in the world. The risk of sustained hearing loss is correspondingly high in these professions. It is important to remember that the louder the noise, the shorter the exposure should be. People who are exposed to permanent sound levels of 85 dB or more at work, must wear ear protection. The pain threshold is around 125 dB.
In bars and clubs around the world, bartenders and other personnel are exposed to noise levels of up to 110 dB for hours every day. Nevertheless, hearing protection is usually not an issue in this industry.
From just a few feet away, jet engines are excruciatingly loud. Without reinforced hearing protection, hearing would be irreparably damaged within minutes.
Musicians need to be especially careful with their hearing. Yet for instrumentalists in a large orchestra, it is usually quite the opposite: Studies have shown that professional musicians are four times more likely to suffer hearing damage than the general public.
Who'd have thought? Dentists and dental assistants also risk hearing damage in their line of work. This is due to the screeching and whistling of drills and other devices, which can bring noise levels up to 90 dB.
Road construction workers
