When the hard wood floors be replaced the subfloor was removed creating a nouns problem. Is there a passageway to effectively deal beside this problem? Easily hear what is going on in the crypt and on the first floor which is too annoying.
Answers:    Is there a lower floor, such as a subterranean vault ceiling that you can access? There is sound freezing insulation that you could possible put into place. It's a fiber glass or recycled broadsheet item. My husband used it to sound proof his nouns studio and it works quite very well.
