How to soundproof a hollow core door?
« on: March 03, 2017, 03:58:19 AM »


I'm sure this has been asked before - but wondering how to soundproof a hollow core door with two hinges? The door to my bedrooms is very thin and sound easily passes through it. I've already covered the bottom gap but I think the door itself is still letting a lot of noise in from roommates. And the gaps around the door are too thin to fit weatherstripping so doubt that's a key source of sound.

Anyway I'm renting so can't replace the door, and I don't want to hang too much weight on the door and cause it to fall. Need to be careful. Was thinking of nailing a sheet of MLV to the door but don't want to put too much weight on it. Just looking for suggestions of a material I can nail to the door that will help muffle/quiet sound and not cause any strain on the door.

Thanks a lot.

PS. After doing some research I've been considering nailing a sheet of MLV to my door. Apparently it is very thin and weighs 1 lb per square foot, so with my 12 square foot hollow core door, 2 hinges, I would be adding 12 lbs of weight. Wondering if that's OK for the door to support long term.

It should hold up, I am just not sure how much reduction you are going to see with a hollow door..

Soundproofing requires mass, normally I like doors to be 8lbs sqft. minimum
