Room Acoustics

Your only, expensive, solution: Lead Wallpaper! Yes, it does exist. Put on the wall and doors. Doors should be overlapped at the cracks. Unless you build a sound proof chamber, like hearing tests are conducted in, every thing else is second best. But remember, the lead paper might lead to toxic posion.

Sound proofing in an apartment can be done - no problem. I have just finished my "dedicated listening room in an apartment" project. To increase soundproofing you need MASS. Forget carpets and egg cartons. They are useless.

Djw....can you be a little more specific nn what it is you want to accomplish. What is the issue you have with the way the system sounds currently? Slap echo? Issue with neighbors? Issue with spouse? What?

You may need diffusors verses absorbtion.

Share your thoughts and concerns, e.g. as an apartment dweller, I can not mess up the walls, etc. Why only exterior walls? What is the db level you crank it up to for normal listening?

Folks are here to help, but more information would help us.

Thanks,

Tiger, you might be referring to a product called Acoustilead. Not really wall paper but sheet lead that I have used to insulate a shared wall in a condo. I put up the Acoustilead using hot glue and then put a layer of 1/4" sheetrock over it. It worked great and you couldn't see that it was there. Furthermore, being imbedded in the wall, it was not a health hazzard.

Lead Wallpaper? How in the world would I use my X-ray vision to see what the new neighbors look like.
