small room ceiling

hi to all! Here i need help to figure out how to treat my small room (about 15x10x8 feet) i use it for mixing and recording everything (electric and acoustic guitars, bass, drums, acoustic piano and voice). I thought to make the ceiling absorbent with rigid fiberglass, rockwool and plaster (already have all the materials and enough rockwool to make a double layer). My first questions are: - is it worth to use a double layer of rockwool and the plaster? - could it also soundproof with the floor above or it is not worth anything if all the room is not floated? - should it be a little skewed to eliminate standing waves occuring between floor and ceiling? Thank you and sorry for my bad english! Omar

Have you actually read any threads on this forum? If not, do so. If so, do it again. :wink:

Omar - I understand that you - like many - are new to the forum. Folks here get the same repeat questions over and over again. Not everyone is "forum-savvy" and know exactly what to do in terms of questions and such. There is a very useful section for people to read up on if they really have little construction expertise. http://www.johnlsayers.com/phpBB2/viewtopic.php?t=2125 Read through these examples and then ask some more pointed questions. Hope this helps - and welcome to the forum.

thank you anyway, i understand!
