Dennis. You are such an important voice in this universe called "acoustic education." Your brand is dependability. The blackboard, no frills, and plain speak provides first to "last word" on this subject. Thank you.
yeah... although oftentimes i hate the fact that physics is physics and I don't have the dimensions to fully form a 60hz wave in my room lol!! alas I revert to DSP.. which I think Dennis needs to do an updated video on--hint hint.
We do not subscribe to electronic manipulation to get the music to "fit" into the room. We have tried many of these softwares but were always left with wanting more sound quality. It is best to minimize the acoustical issues in the analog domain within the room.
FR701 fabric is cheap, their foam is super expensive and you have to buy bunch of them (can't just buy one sheet) and it's not any better from all the other foam oit there. My friend used their foam and it sounds really bad. The best is OC 703 it really works. So tried of their false claims
Great video. Intresting as I recently commented on a diy TH-cam video about building your own foam panel boxes. I mentioned Acoustic Fields had the best foam panels in the market and the measurements to prove it. I just went back and tried to find my post. Maybe it is still there, but I couldn't find it.
Open celled foam technology by defintion is not rigid enough to support itself. A simple solution is to build a wood frame around the foam. This gives the required rigidity and allows for the foam to be hung on the wall similar to a picture frame.
Cheap materials that were never designed for acoustical treatment produce cheap sound qulaity. It takes special material types with proper rates and levels for music and voice.
I would say at the very least, if you're on a tight budget (imagine an adolescent 12 or 14 years old), and you sort of have to buy cheaper foam because you only have $100 or $200 and you can't spend any more, and you want to try treating your first points of reflection to tame 500 Hz and up reverb or something - don't buy that cheap foam if the manufacturer doesn't provide ASTM C423 testing data. Also stay away if they do provide the data - but only an "average/overall NRC" rating. Not even the world's finest foam is completely flat in NRC across the frequency range AF isn't afraid to show you their curve. If the sellers don't want to show you where the peaks and dips in their absorption curve is, there's a reason for that. It's probably not even mediocre acoustic foam, it's just crap.

@@AcousticFields Even with low frequency energy?? say
How does this compare to Melamine Basotec?
You will need to compare the data for both products. Look for linearity in response with no spatial irregularities.
So is it impossible to create diy acoustic panels with bed mattress foams
Yes. A closed celled foam lacks the proper rates and levels of absorption for music and voice.

Thanks as always!
People want cheap. Mix that in with fancy marketing words and that's a recipe for misinformation. Perception is reality.
