Nice pics on that one and well described.

The most complete guide I've found:

The absorption ratings for some commonly used DIY acoustic material.

I actually see numerous problems with that article, so I'd take it with a grain of salt.

For example:

quote:
This rule of thumb generally extends to floors as well, so try to opt for a hard wearing carpet rather than a laminate or hard wood floor.


Having a carpeted listening space can actually cause a lot of problems, because the carpet only absorbs higher frequencies. You are actually better off having a hardwood/solid floor and putting broadband absorbers on the ceiling. Especially if you are recording in that room.

That being said, I actually prefer to work in a carpeted room because it's all I've ever known. I am in the process of building my new home studio at the home I just purchased, though, and I am going with a hardwood (laminate) option this time. It will take some getting used to, but I feel it will be better for me in the long run. (It gives options... even if I feel the room is too "live" and I can't get used to it, it looks much nicer to put an area rug down than it does to put plywood boards down on top of carpet.)

He also mentions that this is the ideal listening position in an oblong space:



While facing lengthwise into the room is correct, that positioning is wrong. The ideal spot to listen is typically ~38% back from that wall, not right up against it.

That being said, there is some good information in that tutorial, if you're new to the idea of treating your space. I just felt I should mention a few things, since I'm finally getting ready to foray into the realm of acoustic treatment after all these years.

Maybe not as great as that site, but worth checking out:

Thats a nice chart but is there a way to measure the "add up" absorption effect of all the stuff in a space?

Good and very valid points but I think that tut is really aimed at a beginner. For someone just starting out it's fairly good and one of the more modern tutorials.

For someone like you though, having the option to choose materials, building the space, and having prior experience, the tut does fall short.

Also, I thought some of the diagrams were misleading (liek the monitors not being at head height etc.).

Agreed... also, the line diagram didn't indicate that the monitors would point inwards towards the listening position (but, it was mentioned in the article, so I didn't bring it up). :)
