For these Lenrds you could put a fiberglass board in front, and use the Lenrds as some kind of filling, to simulate chunks.

thanks Eric, I know it works, thanks to the board in front... :) It is just a little painful.. ... over $640.00 only for filling 4 cavities... it cost more than a dentist !For these Lenrds you could put a fiberglass board in front, and use the Lenrds as some kind of filling, to simulate chunks.
I think you would, it's the best solution to get a live feel in a small room. If you try singing in front of a poly I think you will like the sound coming back to you. It's like having an "Acoustic Monitor ©"I'm not sure if I like diffusion near the instruments...
B.D.R. If you want to do something about that, but it costs energy and whether it helps or not I don't know, is writing them a letter. If you do you can refer to my related posts. I'll gladly defend my point of view in public. And you can tell them, that this will become more and more emphasized as misleading information and a lack of good will from their part. Basically Auralex is aware for years already that the by them published measurements, DO NOT REPRESENT, the function they are sold for. On their site there is a measurement report (which in as far as I assume is not complete) and which is extremely confusing. Even experts have a hard time analyzing what and how is measured here. And even after analysis by an expert, they can only conclude that measurement is useless. The manner this data is used and published by ALL their distributors is just completely misleading, and they can only do that, by silent or written agreement between Auralex and these distributors. I call that wittingly misleading potential customers, which for me relates to ethics. I wrote some other post about that here too: http://www.johnlsayers.com/phpBB2/viewt ... ght=#60309 Now there was a VALID reason it once became that way. Auralex has no reason whatsoever, being aware of the misleading character of that measurement, certainly for physical acoustical laymen which are their main target, to let this situation exist. And I do NOT allow any of their competitors to use this post in whatever direct or indirect manner for the benefit of proving their superiority, even when disguised as so-called altruistic educational help. Because, most trying to use this out of context, are as, or even more guilty themselves of such questionable techniques.thanks Eric, I know it works, thanks to the board in front... :) It is just a little painful.. ... over $640.00 only for filling 4 cavities... it cost more than a dentist !For these Lenrds you could put a fiberglass board in front, and use the Lenrds as some kind of filling, to simulate chunks.
Thank you very much Eric, this acoustic stuff it's difficult science...not to easy for a musician to understand . one more things... . Foam improve sound isolation? Is this true? . I miss interpreted this?: Auralex wrote: ------------------------------------------------------------------------------- We do have many customers who can not fit all the products we have prescribed into their immediate budget, and request an order or which products they should get first. I would definitely suggest purchasing the 2” StudioFoam first, as this is one of our less expensive products and will provide dynamic performance compared the existing treatment. Especially if construction material is out of the question, I think this will give you the best results with cost in mind. Next, I would recommend the TruPanels for corner bass trapping. By absorbing some of this sound, slightly less will be transmitted through the walls, however, again, sound isolation is not the primary function of these products. Also, concrete flooring is generally not recommended for any type of recording or rehearsal space, simply because it is very reflective of mid and higher frequencies. By adding carpeting with padding underneath or some finished flooring to this space, you will reduce the harsh reflections coming from this surface as well as improve the room acoustics for live recording.---------------------------------------------------------------------------------- thank you Eric...B.D.R.

B.D.R.
In order to judge communication, between whoever, I should want to see the exact communication from both sides, in order to see everything in the right complete context.
In general absorption is no insulation, but can be part of insulation if used in a cavity between a paneling system as e.g. a wall.
But in fact they confirm that in that text by relativating the effect on TL by adding absorption.
That sentence about a slight decrease in sound leaving the room is a bit page filling not understood by laymen, and partly compensated by increased amplifying or harder playing (hence this is theoretical stuff in the margin).
The True Panels they refer, result from the current evolution in the foam world, of going to flat absorption materials, leaving a bit the magic of the former foam sculpting psychology.
I certainly can't agree with this, but I rather stay out in this kind of discussions. If true, I only build very bad things until now, because I try to keep floor as reflective and neutral as possible, unless I need some very local problem solution. If it was just me believing so, I could be wrong, but mostly I leave some quite happy faces..... Also, concrete flooring is generally not recommended for any type of recording or rehearsal space, simply because it is very reflective of mid and higher frequencies. By adding carpeting with padding underneath or some finished flooring to this space, you will reduce the harsh reflections coming from this surface as well as improve the room acoustics for live recording.
So the TruPanels can be installed inside the walls for isolation :P ? I will be more than happy to show you the exact communication. But, too late for isolation modifications now... Just past and copy the text here, fax it, how?

Yes you could use True Panels inside your walls to increase isolation.
But it should be completely senseless.
The best absorption to put inside a wall is low density fiberglass or rockwool or whatever cheap comparable product at a fraction of the price and acoustically possibly/likely better.
This does NOT mean that True Panels aren't good or worth their price (that's subjective), but that you have to use materials how and where they are meant to be used.
Putting True Panels in a wall equals trowing money away with a possible lower TL effect.
Acoustics is physics/techniques, not the magic of materials.
About that conversation with Auralex.
What I'm scared about, if you do this public, that competitors will misuse this out of context (there are experts in misusing whatever they can).
And if you send this privately (which you can via PM) I'm a bit scared I commit myself further than I have the energy to put in it.
Well, publishing the room analysis, at this point how much it's going to help any ways... I mess up with isolation already... and then spent over $1000.00 in foam, started from scratch several time after re-painting all the walls, "I will not use Tubetek glue anymore ..." At list I'm learning about room acoustics after all.. hopefully my dreamy tracking room will be usable soon. bu I do have a couple more questions about all this. I will post my last measurements and questions later. thank you MY NEW THREAD http://www.johnlsayers.com/phpBB2/viewtopic.php?t=10467 MEASUREMENTS & CORNERS EXPERIMENTS, HERE FROM PAGE 2 TO PAGE 7Yes you could use True Panels inside your walls to increase isolation.
