Unless they wear protection, these professionals don’t stand a chance when it comes to their hearing
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.
