Myth: Excessive noise won’t cause hearing loss.
Any sounds above 85 decibels for an extensive time can contribute to permanent noise-induced hearing loss. What does that mean? To put that into perspective, a typical conversation is around 60 decibels and is unlikely to damage your hearing. A hair dryer or a power lawnmower is 90 decibels, while an ambulance siren is 120 decibels. Regular and prolonged unprotected exposure above 85 decibels is considered hazardous. Noise-induced hearing loss can occur in work environments, like in manufacturing, construction and any environment that uses heavy machinery. The louder the sound, the shorter the amount of time it takes for hearing loss to occur.
