room 'panels'

[Sly]

having read this months HCC mag i have noticed in the featured home cinema they have used panels on the walls to cut down on sound reflections and offer a (small?) amount of noise dampening.
have any of you guys tried this?

Am currently building a load for my cinema.... i built in pretty serious cavity stud walls all round to cut out low frequency resonance , but this does not really help to control errant high frequency refections so after some testing I decided to panel the walls at intervals.

The panels are of different thickness and are all intercahngable.

what sizes compared to what sized walls?have you done any tests?what materials are you using?
sorry to be a pest!

Sly,
Have a look at this thread, Rockwool rigid slabs - suitable for acoustic treatments? It might give you a few ideas.

My walls are:
10ft (screen and rear wall)
14ft (side walls)

at the moment the panels are 2ft x 6ft

They are of wooden frame construction filled with studio grade 2" thick very dense acoustic foam.

the frame is then to be covered with cloth (when i can choose it!)
