Soundproofing certain walls in an apt.

Post Reply | Watch this Post

Hi all,

My apartment shares 3 walls with the elevator shaft of my bldg (1 Wall at the entrance to the apt., 1 wall at the foyer, and 1 wall in the closet of my bedroom).

Although these 3 walls are solid concrete, I still hear the thumping of the elevator doors closing, and the hum of the elevator motor going up and down.

Can anyone please recommend a course of action for soundproofing this (at least in the bedroom) ?
I was thinking of laying material and then drywall on top of it. Would this solve my problem ?
Does anyone know where I can buy the material, and what is the absolute best product. I would say the sound is mostly mid and low range frequencies (since most of it is muffled by the concrete walls)- and i understand that these frequencies are harder to stifle.

Any suggestions are greatly appreciated.

Please email nyshai@yahoo.com as well as post.

Thanks
Shai
