What is a good inexpensive way to soundproof my ceiling? ?

Making a room soundproof would be very difficult and expensive, but you could make one a lot quieter by adding polystyrene foam to the ceiling. You can get 1 1/2" sheets at Home Depot for less than $12 per 4 x 8. It would be easy to install and would help keep noise in a room, like a basement.

They used to sell homasote, which is basically ground up newspapers as a sound barrier, but I don't know if they still do because I couldn't find it on their website. It also comes in 1/2" x 4' x 8' sheets and is used in a variety of industries. We use it at the theater where I work to make sets sound less hollow, or to keep things from thumping. It cuts easily, is fire resistant, and can be attached with staples or drywall screws.

I assume you're trying to isolate a room so someone can practice a musical instrument or to keep the racket from a basement rec room from disturbing an entire house. Whatever you put on the ceiling, it needs to be attached without any gaps and it might take more than one layer. If you ever plan on selling the house, the installation needs to either be temporary and easily removed, or permanent and properly finished, with a standard finish on it so it doesn't look too weird or be too low. I would try a layer of homasote first, and then if it isn't quiet enough, put a layer of styrofoam over it, though that would be soft and very easily dented, so you could reverse them. Homasote can be painted with regular interior paint or covered with ceiling tiles, which will also absorb sound.

Do they sell anything at home depot that I could buy and instal myself?

Soundproof a ceiling? Wow, that's tough! You have to provide a completely separate floor above so the joists don't conduct the sound. You might ask at the handyman store if there are easy ways to do that.

In short the answer to your question is YES, you can soundproof, but it can be ... To the best of my knowledge, the only way to insulate a ceiling (which .... so it was not built on-the-cheap and actually has decent floors/ceilings.

Get matress foam they sell in all bed stores or egg cartain boxes. All u need is a staple gun

You could spray it with some sound deadening paint ($20). depending upon the level of unfinished.. .you could insulate and rock it with 1in sheet rock
