Approximately 30 million workers are exposed to hazardous levels of noise on the job. Up to 60 percent of workers in certain fields experience hearing loss by age 50. According to the National Institute of Health, sounds below 75 decibels are considered safe. Prolonged exposure to sounds greater than 85 decibels will result in hearing loss over time. Noise-induced hearing loss is 100% preventable. If you work in a noisy profession, you should take steps to protect your hearing.
