And does this mean that when HiFi World measure the resonances in tone arms with their B&K accelerometer, they do so in a sound proof room, with air pressure regulation, free of air tremour and so forth? I think not!
The tests I do are straight forward to do, anyone could do them, and give good enough results to be useful. Call it pseudo-science if you like, but it is helping a lot of people, who seem happy. I could not wish for more. And I have talked to and helped some very good people, some of whom make HiFi components which have won awards (whatever that means).
I'm not answering any more of your idiotic rhetorical attempts to fluff over your mistakes Bryan. Twisting words and rhetorical b.s again!
The numbers posted in regards to acoustic impedance's of materials is measured in ultrasonic, what does that have to do with mechanical resonance as measured by Hifi World and how does that validate your comment that ´ultrasonic measurements bear no relation to other sonic and waves'? Just answer that if you can or any of the other comments made with out wandering into other subjects and theories.

What formula is that? or should I notify the Nobel comity that you are up for a prize having turned the laws of physics on their head? Or maybe your "correcting" of formulas explains what ld was hankering after in suspecting your methods and conclusions.

Yes you recived a sample of my resin-bentonite mixture (not from me I might add) but the mixture was made to my exact recipe
Right down to grain distribution/size and charge of bentonite and the exact type of resin to be used. You then fuddled around trying to understand it's properties and trying to improve on it using same or similar materials before posting my original recipe on your website when you couldn't do so. (with out my consent) You then grudgingly mentioned my "help in development" much later, but only after I argue with you like usual about what constetuted a discovery, invention ect and that you were accrediting others with their input (but mostly your self) otherwise I wouldn't even have gotten a mention. I think this kind of sums up your "scientific rigour
" and generous self-less "helping of others"
The Bento/poly mix was concieved of, measured, developed and perfected with out any of your input
and I looked at your "measurements" of it's mechanical resonance and damping
as just another objective observation.
It was developed for a specific purpose taking into special account acoustical impedance in relation to acoustical damping and matching to other specific materials I was researching and utilising at the time. Like lead.
As to getting carried away with numbers I quote you from a former post citing one of your instructors "why spend 30 minuets at the library when you can spend 3 months in the laboratory?" You were referring to those who at the time were building plinths without exploring the physics behind it. Bryan it's about time you popped of to the library for a quick 30 minutes. Especially if your going to keep trying to come across as some sort of authority on this whole subject and not in the least if you are offering your "measuring" services to others for a nominal fee.
