Not only does noise in the workplace have the potential to damage workers’ hearing, but there is evidence that workplace noise may also raise blood pressure and cholesterol levels among workers exposed to elevated noise levels. This is an important finding because hypertension and high cholesterol are listed as top risk factors for heart disease. With this in mind, workers in mining, construction, and manufacturing should be particularly diligent about having their hearing checked. Beyond that, workers found to exhibit signs of hearing loss should not only take preventive measures to reduce their exposure and treat their hearing loss, but they might also want to schedule an appointment with their physicians to assess their heart health. 


P.S. Long-term exposure to noise levels at 80-85 decibels or over can cause hearing loss. Heavy city traffic is 85 dB.
