Soundproofing Cieling

Discussion about
Would I add to the value of my apartment from soundproofing my ceiling? Primary concerns are low frequency media noise, creaky joists and footfall. It is a prewar wood frame building. I am now at the point where I don't want to come home at night because I am uncertain if there will be echoing from upstairs. My neighbor is respectful but don't think to come off super unreasonable and am thinking the soundproofing could be an alternative.

No as most people expect a certain amount of soundproofing. But basic soundproofing ceiling is not expensive. There is soundproof drywall available.

Of course, if you are expecting studio quality soundproofing, it can get expensive.

The link above from Lowe's specifically says "Not recommended for ceiling applications". I am also looking for something similar to dampen creaky floors from the neighbors above.

Does your neighbor have appropriate carpeting? Most buildings require 80% of floor surface (except for kitchens, bathrooms, closets and the like) be covered to mitigate sound.

BTW, football should not be used after 7pm. I can hear football through my 18 inch thick hollow brick ceilings. Soundproofing will not fix that.

It is extremely difficult to stop low frequency sound. The thickness of the sound insulation needed is proportional to wavelength, which is inversely proportion to frequency (i.e. the lower the frequency, the thicker the insulation needs to be to stop it from propagating).

The way to stop creaky joists is to rip down the current ceiling and place blocking between the joists and/or sistering the current joists with reinforcing members.

Great thanks to all - I read about decoupling the ceilings works for sound and helps a lot with footfall (loud steps). I just don't know if it adds value to the apt though. I am downtown.

I installed a new sheetrock ceiling with Owens Pink fiberglass r30 between the joists, then hung a grid using Chicago bar (https://www.youtube.com/watch?v=oSb-dMZk4Fc) and used isolating c-brackets to hang the sheetrock.
