Hearing loss can occur when exposed to 85 decibels of noise averaged over 8 hours. Let’s put this in perspective. Normal conversations typically occur at 60 decibels, well below the hearing loss threshold. For every 3 decibel increase past 85 decibels, hearing loss can occur in half the amount of time. So it only takes 4 hours of exposure to 88 decibels for hearing loss to occur, and 2 hours of exposure to 91 decibels. Once noise levels exceed 100 decibels, a person can suffer hearing damage in as little as 15 minutes.
