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

Yep. Same here. I have my stands on spikes and on painted black concrete slabs (14X14). Works very well.
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,

I would go with monitor speakers and a sub woofer. At night you can lower the output of the sub.

Keep it simple.

Or you can pour 3" of light weight concrete over your existing flooring. Then you can go with monitor speakers and a sub woofer.

Speaking from experience.

Good luck.
Anything you put under the speakers will change the sound. You may be able to increase volume, but not like the results.
