Sound Proofing a Theater Door

mufsoman

Anyone have a good suggestion of how to sound proof a standard door frame? The door at the top of our stairs is a standard wood frame with a six panel solid pine door. There's a large gap along the bottom and a gap around the door stop molding. With the theater area down stairs and the family room on the first floor, there's a lot of sound leakage between the two rooms when both are being used. Thoughts?

can you add a second door at the base of the stairs?

perhaps you could construct a facade for the basement side of the door that overlaps the door jambs/framing that consists of sound absorption material and then put a nice textile over the top of that.

There are many ways to approach soundproofing. First, you may want to be sure you have a solid core door. Standard rubberized door seals will also help. Specialized door seals are also available for the perimeter of the door and threshold as well as automatic door deals that will engage when the door is closed. Zero International makes door seals for these purposes. Creating a door lock with another set of doors is also a viable option. If the doors are properly sealed and you are still having issues, the sound may be transmitting directly through the wall structure. This type of sound can be blocked by adding massive and dense materials such as mass loaded vinyl sound barrier or additional layers of sheet rock. You can also attempt to muffle and lower the overall sound pressure in the room by adding fluffy acoustical materials to absorber the sound. Even though an absorber does not block sound it can prevent the sound from bouncing around the room, reducing the overall sound level.

I would first fix what is obvious large gaps with a door seal. Then remove trim molding to check behind there, you maybe surprised as to what you find. If this is empty fill in with some expanding form, then re-install molding.

I want to say Lowe's sells a product called Daptex by DAP. Like Joe mentioned, it's a spray foam in a can that's made for smaller gaps around windows and doors. It doesn't expand to crazy dimensions like some of the spray foams. I need to take off some of my trim molding in the HT room and check this out too.

I reported post #4, but it's the first responsive spam I've seen so maybe it's OK???

Where Jesse when you need him? :biggrin:

Tour2ma, are you referring to acousticsfirst post up here? I thought he offered some good info and tips. I was already familiar with most of the info he mentioned since I too am trying to do some soundproofing, to do it right costs a lot though.

Agree, but both links went to a commercial site that is his 'screenname dot com' and I am not sure that is kosher...
