I feel so sorry for anyone whos gonna live near that thing

At full speed those trains sound like a formula 1 track during a race. (And thats before they went from V8s to V6s

Rubbish. With around 75-80 dB at 25 meters, high speed trains at 300 kph are about as loud as 6 lane highways, and unlike the highway that is for less than 6 seconds to a stationary observer. A V8 formula one car was ear damagingly loud at more than 130 dB.

edit: Here's a German ICE train going 300 kph through a station if anyone wants to get a rough idea of how a modern high speed train sounds relatively up close.
