Im looking to get a new home with a roommate. They will be upstairs and I will be downstairs. We are basically doing a complete renovation of the home including completely redoing the floors and the basement ceiling is currently unfinished so there is no limit to what we can do. Im more concerned with peace and quiet than I am with the cost of soundproofing (within reason) and I am VERY sensitive to impact noise from upstairs. All impact noise needs to be completely eliminated.. I dont ever want to hear any footsteps, things dropping on the floor, her kid screaming, ANYTHING. I need peace and quiet in order for that living situation to work. Is this possible? There is a wealth of information on soundproofing techniques on the internet and very little on how effective it actually is.
