Room treatment ideas for annoying external noises

big challenge is dealing with noises that come from outside the room.

Noisy landscapers from your neighbors, a dog barking, and inside from the refrigerator compressor buzzing all the time.

Anyone try to deal with these noises and how best to do it?? Thanks


Better windows, noise blocking doors with air tight seals are a place to start.  Noise blocking  curtains as well. After that you are talking about double layered drywall.
