Researchers say installing 100-meter-long porous, soundproof buffers at tunnel entrances, along with a porous coating along the interior, can cut tunnel boom intensity by up to 96 percent. The material works by letting compressed air escape before the train bursts out of the tunnel.

Sounds conceptually similar to how firearm silencers work.

@CameronDev @Zachariah It is also conceptually the same thing happening :)

If you put little foil pinwheel propellers along the buffers, everyone can have a good time!

WHEEEEEEEEEE!!!!!!
