RE: AV Room

That just deadens reflections and echoes within the room.

 

It doesnt stop sound escaping. It will travel through any solid material. To properly kill it you need all kinds of floating walls etc.

 

There was a system on Tomorrows World about 20 years ago using "Anti-Noise" where you generate an equal but opposite level of sound which when summed t gether produces silence. OK for known noise like Aircon drone etc but not very good for dynamic sound such as music or movie effects. Also requires SERIOUS computing power and lots of Amps/Speakers/Mics for the Antinoise.

From what I have seen of sound proof test chambers, keep all those old egg cartons and stick them t the walls. :o)

Wey Hey! it looks as though I will be able to convert our Den int a bigger room for AV use. I know several of you have dedicated AV rooms, what materials did you use for construction, I have bedrooms above so noise insulation  is important. Are there any design criteria as to ceiling height to floor area, should I have heavy curtains at the back to stop reflections?
 
Any advice would be appreciated as I am at the design stage now.
