That’s the kind of attitude that has turned the ears of Noise-free America. "It isn't the loudness. It's the vibrations. Those subwoofer vibrations, and low frequency vibrations," says spokesperson Judy Ellis. "We all know that it's bad for your ears, any exposure to decibels over 90 begins deafening process," she says, adding, "Emergency workers, EMT, fire … their sirens are not being heard at intersections.".
they say that 90db is loud for low frequency.
the ****in sirens on fire trucks are atleast 140 dbs
