Title: Soundproofing an air gap between the entry floor and my basement room
Post by: tmcmoore on October 08, 2017, 11:23:38 PM
I'm living in a basement apartment, but for some reason the original designer left about a foot airgap between the wall and the stairs up to the second level, so I can hear everything that happens in the house as if it's in my bedroom.

Here are some pictures:

I'm thinking of making something with a wood veneer and some rigid foam insulation to help dampen the noise. Is there a more obvious solution I'm not thinking of?

Thanks.

same principle as a window plug.

use a nice heavy wood as a backer for rigidity and make sure it seals air tight like a cork in a bottle.
