sound proof floor - practical examples?

hello. i am in a condo on the top floor, it has decent sound proofing but was built in 2000 or 2001. i've read up on sound proofing, preventing my stereo sound from being too loud downstairs, but i'm wondering if anyone has an practical examples where it helped or didn't help.

for example i was thinking of 2.0lb/ft MLV and closed cell foam under carpet pad and carpet to help me turn up my volume a little. right now i'll pop in jazz or vocal, classical and get anywhere from 40db (which is pretty much silence in my space) to 77db peaks. i'd like to go a little more than that, 88db peaks maybe?

thanks

I've found that not everything drains vibrations the same so there's going to be some feedback into the speaker. Different surfaces will or can make a speaker sound brighter or duller than what you'd like.

Don't be afraid to experiment with footers, spikes, discs for the spikes, wood, granite, concrete, etc. Eventually, some combinatin will work best for you.

I've read somewhere about some type of rubber layer (not that thick) that lies under the padding that works wonders to quell sound. Good luck.

All the best,

It would be nice if soundproofing was one of the prime considerations in apartment and condo construction. I remeber way back in the day when friends would brag about how their apartment was soundproof. They just don't build them like they used to.
