Background Noise exposure and noise-induced hearing loss (NIHL) are common worldwide, but the contributions of common noise sources, such as mass transit, to total annual noise exposures have not been adequately explored among urban residents and workers. Methods We estimated noise exposures associated with five common noise sources (use of mass transit, occupational and nonoccupational activities, MP3 player and stereo use, and time at home and doing other miscellaneous activities) among a sample of over 4500 individuals in New York City (NYC). We then evaluated the contributions of each source to total noise exposure, and also compared our estimated exposures to the recommended 70 dBA annual exposure limit. Results One in ten transit users had noise exposures in excess of the recommended exposure limit from their transit use alone. When we considered total annual exposures, 90% of NYC transit users and 87% of non-users exceeded the recommended limit. MP3 player and stereo use was the primary source of exposure among the majority of urban dwellers we evaluated. Conclusions The vast majority of urban mass transit riders may be at risk of permanent, irreversible NIHL from noise exposure. Use of mass transit made an important contribution to the exposures, as did use of MP3 players and stereos. |
