约2800万美国人听力受损,其中约一半与噪声暴露有关。听力受损的人因社交减少、孤独、被排斥感、沮丧和可能的认知功能受损而导致生活质量降低。由于30%～50%的毛细胞受损害后才能测出听力受损,故目前噪声性聋很难早期发现。不仅持续噪声暴露有耳聋风险,而且单次暴露也能引起耳 About 28 million Americans suffer from hearing loss, about half of which are related to noise exposure. People with impaired hearing due to social decline, loneliness, exclusion, depression, and possible impaired cognitive functioning lead to reduced quality of life. As 30% to 50% of hair cells damaged to detect hearing loss, it is difficult to early detection of noise-induced deafness. Not only does the risk of deafness continue to be exposed to noise, but a single exposure can also cause the ear
