Acoustic Neutralisation

[ghettosla]

I am looking for tips on acoustic neutralisation as i am going to invest in some(this action being prompted by the echo which must be killed)...

That is the complicated matter. The best way is to consult with the acoustic specialist, but there are some tips. If you are talking about control room then the room should be symmetric. Good thing is to avoid parallel walls, ceiling and floor. It is good to eliminate corners between walls. The floor usually covered by soft carpet of natural material (wool is the best).

Never heard it expressed that way, but sure.

Room treatment is a deep subject, and a complete answer requires far more than will fit into a single reply here. So here's the short version which will get you 99 percent of the way there. All rooms need:

* Broadband (not tuned) bass traps straddling as many corners as you can manage, including the wall-ceiling corners. More bass traps on the rear wall behind helps even further. You simply cannot have too much bass trapping. Real bass trapping, that is - thin foam and thin fiberglass don't work to a low enough frequency.

* Mid/high frequency absorption at the first reflection points on the side walls and ceiling.

* Some additional amount of mid/high absorption and/or diffusion on any large areas of bare parallel surfaces, such as opposing walls or the ceiling if the floor is reflective. Diffusion on the rear wall behind you is also useful in larger rooms.

For the complete story see my Acoustics FAQ.

There's a lot of additional non-sales technical information on my company's web site - articles, videos, test tones and other downloads, and much more.

I like that! This is a great way of looking at it in my opinion.
