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?

I have watched maybe 10 of his vids.  It was worth the time and provided food for thought.  But he completely lost me when in the last one I watched he went off on the "industry" selling extremely harmful substances like fiberglass and Roksul.  He was claiming that they are as harmful as asbestos.  Went on to say that playing music would shake fibers loose (even if covered) and of course you would breath them.

He stated that he uses granulated charcoal as a sound barrier between walls.  I will admit if you are soundproofing his wall design did look very well thought out and of course uber $$$$.

Yes it's true. Asbestos miners working ten hour days breathing a gram per cubic meter asbestos dust develop lung disease in as little as 20 years. The microscopically infinitesimally immeasurably few bits of fibers you might inhale listening to music an hour or so a week is dead certain to give you cancer, and probably only in five or ten thousand years. 

The one thing this bozo is right about is no way you can put a panel on the wall for less than a grand. They can't be anyone else's panels, those guys don't even know about all these invisible astronomically non-existent non-risks. We cannot even begin to estimate the cost of room treatment until we know your net worth.  

And I know what you're thinking, but we already know your gullibility and susceptibility to BS is sky high, or you'd never watch these stupid videos. So all we need now is your money.
My last home had a concrete acoustic ceiling. No asbestos laden soft material. It was heavy and would require a rebuild of the entire ceiling to remove it. But why do that? 

That kind of ceiling makes for a great sounding room. It was 19 x 29. It was a den/living room that was my dedicated listening room. The issue: Stone and wood and one side wall and nothing but drywall on the other side wall. But it was a fixable problem.

Sometimes what you are dealt with, by sheer luck, is a great sounding room.  The bass response I got from a pair of salk Songtowers was simply evil...and not boomy at all...just deep and clear as sin. Then I moved.

I think we gotta work with what we got. Each room has it's sonic signature..and is unique. 
Some just require a lot more work. 
If anyone here has 68 k to spend on room treatment I will take the job. I will get it done over the top for 10k and pocket a 58k profit for my work great gig if you can get it!
No...not really.  Thoughtful room placement of speakers and furnishings, using Mapleshade’s speaker placement advice should suffice for most listeners.
