Approximately 30 million workers in the US are exposed to hazardous noise on the job. Audicus tried to compile the available data on the incidence of hearing loss in occupations where the average noise levels are above the 90dB safety limit – and the numbers were astounding. In manufacturing or even agriculture, workers are at least three times as likely to experience hearing loss when they are 50 years old– in other industries it’s up to six times!
