Seems a new study that compared the numerous mass transits modes available in NYC has found that subways, with noise levels ranging between 80 and 102 decibels, were the loudest means of transport around.

That’s not good.

The EPA and WHO both recommend that in order to protect your hearing your daily average level of noise exposure should be no more than 70 decibels. To give you an idea of the level that is, normal conversation is between 60 and 70 decibels.

The study’s results indicates that the estimated 33 million Americans who use the subways daily are consistently over exposing themselves to potentially deafening levels of noise.
