Soundproofing Doors at Home Depot

The walls of my listening room are pretty solid, but a fair bit of noize seems to leak out underneath the door, which then echoes into the hallway which is acoustically bright and reflective.

Consulting websites which are devoted to soundproofing, I have found some impressive but very expensive solutions: seals which move up and down, lead lined recording studio doors, door sized covers etc etc.

For my purposes, I would greatly appreciate any advice on how I might install a simple, inexpensive solution for this old wooden door which has a gap of at least an inch.

Would home depot have a seal that you would recommend? A heavy rubber flap for the door jam?

Has anyone had success doing this yourself?

cheers

Thank you everyone - wow this topic seems to be of greater interest than I expected.

Advice along the lines of the sand filled sock and the gasket is what I have been hoping to find.

I cannot change the door to this room - it is already a heavy, exterior type door with panels and moldings. Nor can I change the decoration or surfaces in the hallway.

The main issue is the gap underneath the door, and I was hoping to avoid the mechanical gap sealing device that I have seen for studio doors.

So please keep the suggestions coming and I will hope for a greater than "middling" solution for less than a middling price.

cheers

Well yeah, if that's all you can do, the first thought into my head before I posted originally was simply to stuff a bath towel up under the door and maybe install a gasket -- but after perhaps experimenting with a towel, I like Russ' sandtube suggestion as being a bit more elegant. However, for more efficacious results I still think you also need to consider treating the listening room side of the door with some kind of sound-blocking/absorbing material, which your list of prohibitions doesn't seem to rule out.

If you want to save money, why don't you just buy some weather stripping from Home Depot and a threshold? You could at least try this before spending more money on a new exterior door first. You can even make a threshold yourself and use weather stripping on the edge where the door shuts against it.

You could just try a door sweep. They are used on the bottoms of exterior doors to seal the door to the threshold. They are adjustable up and down and they are easily cut to length if necessary. If you are not familiar this link will give you an idea of what they are.

For a few bucks and 5 minutes it may be an easy remedy.
