What is the noise level of a subway train?
What is the noise level of a subway train? Subway noise can range from 80-112 decibels (dB), which greatly exceed the 70dB level set by the World Health Organization (WHO) and EPA for safe environmental noise levels (Gershon, Neitzel, Barrera, & Akram, 2009).
How loud is a subway train?

Can you hear a train coming at you?
“People assume that trains are loud, but that assumption is based on the fact that when a train's gone past them in a station it's noisy. That's because the noise a train makes is mainly projected to either side. When trains are moving directly towards you they are barely audible–until it's too late.”
Why can I hear trains so far away?
When air warms with altitude a temperature inversion exists. Sound travels faster in warm air than it does in cool air. This means the sound of a train horn will bend downward when it passes through an inversion causing sound waves to propagate farther than normal.
Are trains loud to live next to?
Noise pollution and vibrations are some of the biggest concerns, particularly for people who live within one-third of a mile of railroads or railyards, says Natalia Caldeira Loss Vincens, an expert in public health at the University of Gothenburg in Sweden.
Is it OK to fly with tinnitus?
