Hello! I would like to soundproof one of our rooms (about 8m2) that faces our neighbor, which is a preschool with 3-5-year-olds. There are loud children's voices, and it sounds loud when they ride tricycles, etc.
Anyone have tips? I'm thinking a new good soundproofing window is necessary and build onto the walls with something?
