Soundproofing a room for voice recording
« on: March 07, 2015, 06:15:49 PM »
Hi. I need some information about soundproofing, I visited 5 stores and I had 5 different opinions, that's why I'm writing on this forum. Sorry for my bad english, I hope you can understand.

I have this problem:
I have to built a small room (2 metres X 1.5 Metres, 2.5 Metres tall) into a larger cellar, in order to record my voice (dubbing exercices). No singing, no music, just normal voice. I don't need a perfect soundproof, but I want to do my exercices in peace without disturbing anyone and without being stopped by a bit of shame  :-\.

Regarding the structure I already have have two bearing wall (0.30 metres width), and I have to built two missing walls (I thought 0.08 metres width), maybe in drywall or Autoclaved Aerated Concrete (a dealer advices me for the last one ->

But the main doubt is about soundproofing: three dealers said that "Pyramid Soundproof Foam" (I don't know if that is the correct name, I mean these: is enough for what I have to do, but two dealers said the opposite, and that I will need "Mineral wool" combined with some soundproof material, because Pyramid foam are useless.

So, my question is: do I really need "Mineral wool+soundproof material" , or I'm fine with just Pyramid Soundproof Foams?   (I'll probably use Autoclaved Aerated Concrete for the missing walls)

I hope this is the correct section of the forum, and I'm sorry again for my english.
Thanks :)

once you build the walls with the concrete all you need to do is cover the walls with the pyramids..this will work fine for what you are doing..
