Staple roofing felt to the bottom of the ceiling. That will help.

Anything lightweight isn't going to do much. It's easy to prove to yourself. Put a stereo speaker on it's back and cover it with the material. Insulation, egg crates, carpet -- not much difference. Some benefit, sure, just not much.

Low frequency is a lot harder to deal with. That's because low frequency will travel through structural members. For low frequency you need to hang your mass from resilient clips.

Have you considered just getting him a gaming headset?
I want to move my poker table to this room, so its voices I also want to cut out. The ceiling is wide open so itys the last chance that I can really add. It would be n ice to have something on the bottom of the exposed ceiling joists

The door to the basement stairs is the only real sound source now. Not to sure about noises coming from the bedroom to the basement .
Nice idea but I already filled in the area between the ceiling joists

When we had our one room's walls opened up I put old acoustic drop ceiling tiles in the stud bays, glued to the sheetrock. I don't know how much it helps, but I'm sure it does some good.

Mass helps -- the more the better.

Supposedly spay in insulation helps too, but I don't have any experience with that. Seems like it would be super good at stopping air bound sounds.

It occurs to me that since it's a basement room you might have ductwork in the ceiling with an opening to the upstairs room.

If you do, then this is the key area to address.

Duct work is pretty transparent to sound, so basically you have an open hole from one room to the other. Fix that and you'll probably be happy.

Interesting point, noty sure but I think I am safe there. I only have 8 inch plastic tube for the venmar. THis comes into the down stairs room for about 6 feet before it cuts up to the upstairs. I did manage to shove some soundproofing insulation underneath the plastic tubing in the basement. Upstairs, it comes up thru a closet and is boxed in.

Sound proofing


Just a quick note, if you're going to put anything in the wall or ceiling, I'd stick with simple, cheap fiberglass.

Foam is excellent thermal material, and is often marketed as good for soundproofing, however it is not. Odd, but that's what the lab data says. You want light fluffy (uncompacted) fiberous insulation.

I completely agree about the liability of ductwork
