Hi. So I want to convert my family’s home basement into an intergenerational appartement. The problem is that the first floor is only made out of Parquet wooden floor and the basement ceiling is made of suspended ceilling, kinda like in some office buildings. There are guides everywhere to keep outside sounds out, but there is nothing about keeping private sounds in.
Here is an example https://imgur.com/gallery/ofreDX8
What are my options? I can bend my budget for a better soundproofing rating if needed, but still want the most soundproofing for my buck, if that makes any sense.
