No, 705 beats 703 at low frequencies, period. The disparity is due to failings of the reverb room test method at bass frequencies, as explained in my Density Report. Hopefully, y'all will allow me to editorialize a bit:
Acoustics and bass traps are not as complicated as some believe, but it's not trivial either. For someone to look at the standard data as presented by material manufacturers and conclude that's all there is to it is ignorant and foolish. I came by my knowledge the hard way - I tested a lot of things in different rooms. Since my main goal is to educate, I have published all of my findings that are not proprietary. Besides my Density Report and "Believe" article (
LINK), you'll find many other articles describing my original research and findings listed on the Articles page of the RealTraps site:
RealTraps - Acoustics Articles
In particular, see the three "RealTraps Exclusive" articles near the bottom of the list.
I believe that consumers (you guys) benefit from this type of research, which is why I do it and publish the results. I also find this stuff fascinating, which is another reason I work so hard at doing original research. So you'll forgive me if I get irritated when folks who are little more than acoustics newbies pretend to have all the answers, or call me wrong without having done their own homework first. Just because someone sells bass traps does not make them an acoustician.
