I just bought a 40 yr old semi that has original hardwood flooring with a finished basement. My brother in law will be moving into the basement apt and the sound from the tv directly above is horrible (as well as the footsteps) I was hoping to get some input on different ideas:
1) I demo the old basement ceiling and install special soundproof insulation & drywall and screw in the joists/beams and then hire a drywall prof. to finish the ceiling
2) Install a 2nd basement ceiling with a drop ceiling with S.P. insulation
3) Install new flooring in the room above, add a S.P. vinyl, foam, patted sheet after screwing down the floor
What the approx cost for 1 & 2??
Also, what can be done about the vents, is there a special padding or spray that softens the noise coming through? I did not want to move the existing ducts...
