As someone who grew up in an apartment building with concrete floors, I assure you that concrete is useless for internal noise dampening.

As someone that's lived both in a concrete 10 story "high rise" apartment building as well as a 3 story wood-framed apartment building, concrete is far superior for noise dampening as wood.

In the concrete building, we could never hear neighbors above of below us, in the wood framed building, we could hear foot steps and even voices. Our upstairs neighbor had a squeaky bed and we could clearly hear the bed every time they were intimate.

I think the difference is that in wood frame you can sometimes hear things through the walls. Whereas with concrete, any sort of impact (chairs moving, doors slamming, people walking in heels, the guy putting a nail in the wall to hang a picture on) gets transmitted to the entire building.

Concrete is much better at noise insulation than dry wall and timber flooring.

Plaster and timber flooring isn't so bad. Brick is also better than concrete. More rigid materials tend to transmit sound better.
