Don't be silly! Find a nice rug you like and hang it on the wall from a one inch spacer. Maybe a couple of rugs on different walls (on the floor if it's not already carpeted.
Acoustic treatment question: do you agree with Dennis Foley that $46k to $65k is required?
In a video from 1/29/2021 (yesterday) Dennis Foley, Acoustic Fields warns people about acoustic treatment budgets. He asserts in this video that treatment will likely require (summing up the transcript):
Low end treatment: $5-10k
Middle-high frequency: $1-1.5k
Diffusion: Walls $10-15k, Ceiling: $30, 40, 50k

Ostensibly, this is done in the spirit of educating people who think they can do treatment for less than this.
People here have warned about some of his advice. Is this more troubling information or is he on target?
For those here who have treated their rooms to their own satisfaction, what do you think of his numbers?

Just a carpet? Um... https://musicstudiodiy.com/use-carpet-acoustic-treatment/ |
Not to derail the thread, but I too find Foley’s fiberglassophobia off putting and borderline ludicrous. Don’t get me started on perhaps well intentioned folks who invoke metaphysical concepts where they don’t belong, as seems to the the case in this instance. If it ain’t "all natural" or "organic" it is deadly, they seem to think. Never mind the fact that some of the most toxic substances known to man are natural products. Let’s go back to the good old preindustrial days, when people were really healthy as reflected in their average life span of 32 years. OK, I will get off my soap box. All that said, Foley’s use of activated carbon (charcoal) is really intriguing. I can imagine those traps could be quite good. The ACDA 12 has some good activity below 50 Hz where it is hard to find things that work. They are very expensive and no doubt quite heavy, so are they cost effective? I don’t know. |
@brownsfan I agree about the weirdness of "fiberglassophobia." For someone who is ostensibly a scientist and/or engineer, this scare tactic (which he dwells on) is very problematic. Clearly, if people believe him, they have to go with his (non-toxic) alternative which, by the way, is supposedly better acoustically as well. And, more profitable for him. At the end of the day, are his products effective? Are they better? Well, maybe, but either he is honestly misinformed about fiberglass (which speaks to a deficiency of knowledge) OR he is intentionally misinforming others to sell products. Either way, it has a bad odor. |
16.5 lbs/sq. feet, yes they are heavy. Look really peaky though. Lots of absorption at 50Hz, lots at 250Hz. Not a lot anywhere else. Better hope you nodes are there or you may not get what you want: https://acousticfields.com/wp-content/uploads/2012/01/ACDA-12.pdf |
