“According to the Environmental Protection Agency’s Office of Noise and Abatement Control (which disappeared during the Reagan Administration) in order to protect from hearing loss, one should not be exposed to more than 70 dB for an extended period of time. Meanwhile the average city traffic is  85 decibels and in larger cities like New York, the noise level often exceeds 90db. Les Bloomberg, director of Noise Pollution Clearinghouse in Montpelier Vermont, has stated that "87% of America’s city dwellers are exposed to noise so loud it has the potential to degrade hearing capacity over time."
