Block High Frequency Train Noise
I moved into a new apartment, its great expect there is a train about a .5 to 1 mile away. Its not incredibly loud but at night sometimes I can hear the high frequency squeak of the wheels.
What are my most realistic options for reducing the noise at least a little? I don't expect for it to go completely away, but if I could just reduce it a bit it would be much more tolerable. I'm skeptical of heavy blackout curtains, I've seen mixed reviews, but aside from that I don't really know what I can try.
Any advice would be much appreciated. Thanks!
