Some workers in music and sporting venues, and restaurants or bars, may also be exposed to hazardous noise levels. Workers in the manufacturing, transit, and construction industries are at high risk for noise-induced hearing loss. Noise-induced hearing loss is one of the most common work-related illnesses in the United States. Long-term exposure to this type of noise can lead to: Noise in the community, even at levels that are too low to cause hearing loss, can affect mental and physical health. Studies show a link between noise and poor academic performance in schoolchildren. In young children, exposure to noise can cause problems with reading comprehension, concentration, memory and attention span. Hearing loss is strongly associated with depression and cognitive decline. People with hearing loss often become socially isolated due to difficulty communicating and participating in social gatherings. For example, regular exposure to sounds at 100 dBA for more than 15 minutes at a time can cause hearing loss, while exposure to a very loud sound, such as an explosion, can cause immediate hearing loss. For sounds at higher dBA, less exposure can still lead to hearing loss. Permanent hearing loss can occur from routine exposure to sounds at 85 dBA for more than eight hours a day. Loud noise can cause short-term or permanent hearing loss.
