Talk but not walk?


Hi Guys

This isn't meant to start a fight, but it is important to on lookers. As a qualifier, I have my own audio forum where we report on audio issues as we empirically test them. It helps us short cut on theories and developing methods of listening. We have a wide range of systems and they are all over the world adding their experiences to the mix. Some are engineers, some are artist and others are audiophiles both new and old. One question I am almost always asked while I am visiting other forums, from some of my members and also members of the forum I am visiting is, why do so many HEA hobbyist talk theory without any, or very limited, empirical testing or experience?

I have been around empirical testing labs since I was a kid, and one thing that is certain is, you can always tell if someone is talking without walking. Right now on this forum there are easily 20 threads going on where folks are talking theory and there is absolutely no doubt to any of us who have actually done the testing needed, that the guy talking has never done the actual empirical testing themselves. I've seen this happen with HEA reviewers and designers and a ton of hobbyist. My question is this, why?

You would think that this hobby would be about listening and experience, so why are there so many myths created and why, in this hobby in particular, do people claim they know something without ever experimenting or being part of a team of empirical science folks. It's not that hard to setup a real empirical testing ground, so why don't we see this happen?

I'm not asking for peoples credentials, and I'm not asking to be trolled, I'm simply asking why talk and not walk? In many ways HEA is on pause while the rest of audio innovation is moving forward. I'm also not asking you guys to defend HEA, we've all heard it been there done it. What I'm asking is a very simple question in a hobby that is suppose to be based on "doing", why fake it?

thanks, be polite

“But I have to admit now being put off having noticed the character of his posts, and certainly a number of his claims fall well into the dubious woo-woo land of audiophile tweaks, nuzzling happily with things like demagnetizing CDs and many other tweaks that have brought our hobby in to ill-repute).”

>>>>>Unfortunately for your “argument” demagnetizing CDs is actually not snake oil, woo or pseudo science. And even if was, that line of argument is just another one of your many logical fallacies, people that believe in Tuning probably believe in UFOs, that sort of thing. It’s actually people like the professor who are bringing the hobby to ill repute with his long-winded pseudo arguments, diatribes and smear campaign. Better luck next time, professor.

On with the Inquisition! 👺

However, you will have to agree that thread was successful in what you, and I have to admit me too, feel its purpose was. Some of us have gone to the website that we had not gone before, and got informed about it. Now, that is what I would call a successful marketing. I am yet waiting for verdict if my visit was fortunate or unfortunate. I hope to get an answer about laminar flow (asked in one of my earlier posts) as it would be something new learned and, in some way, a breakthrough in my current understanding and practice that relates to laminar and turbulent flow in daily applications. The question is as simple as it gets, the answer may not be, but I am willing to try and be thankful for clarification.

>>>>As I recall there are certain geometrical devices used on aircraft wings to maintain laminar flow, and prevent turbulent flow. Perhaps that’s what his device does, it certainly sounds like it. Why turbulent flow would be a problem in a listening room is another story. But I do not see his lack of explanation to be as big a deal as you do. 
geoffkait,

I have not thought that lack of Michael's explanation/answer of my question is a big deal, although I am interested in an answer. I thought he simply have not read my question either because he has not read thread recently, or he has not paid attention to my question as it was not explicitly addressed to him.


I am in no way an aeronautic engineer and would not be able to discuss the design features of a plane. I believe your statements about wings and that makes me even more curious about its application in the room as stationary walls are not exactly moving in one direction (absolutely or relatively) as airplane wings are. Since yesterday, I have been unsuccessful in locating any explanation of an object placed in the stream of laminar flow making it even more organized (what does that actually mean?). It may be due to my search technique and sources and it may be because I really haven't spent whole sunday looking for it. Still, it is intriguing to me and you opened yet another avenue for my curiosity. If placing something in the path of laminar flow really "organizes" that flow, how does it work in the room? At this point, I am not even interested about its influence on sound, but just plain basic flow of fluids.

I, just like prof, do think that Michael is passionate about what he writes about, regardless if I agree or disagree with him on something or nothing and I do not give him too many negative points for obviously pushing his business here (the man has to pay electricity for his equipment, at least), but I have a feeling he may know something about this topic that I do not. I hope neither him, nor you, find it unacceptable to ask for some knowledge-sharing from those who seem to know better. If it is not acceptable, I apologize.
@glupson - Breaking News!! Laminar in listening rooms!

But first allow me to say laminar flow can be produced either by an aircraft moving through still air or by air moving around or into solid objects like walls. The air is moving because the speakers are producing acoustic waves, I.e., moving air. It’s the relative motion. In a wind tunnel, where laminar and turbulent flow can be studied, the model of the aircraft is stationary and the air is moving, no?

From the Star Sound web site,

”In 2008 Dr. Andrew Gear, a lifelong audiophile, approached Star Sound on the topic of actually developing such a room so that his passion for the ’live performance’ could be realized through his hi-fi system in the privacy of his own home. He issued this challenge to a few companies and in October of 2012, upon receiving various proposals, he decided to invest in Live-Vibe Technology™ infused into the structural design of his listening room.

"It is not every day an experienced listener comes along and takes financial risk in further developing technology atypical to the majority of industry’s understanding of vibration management, investing it into one of his most sacred assets – his residence.

"For a small research and development company like Star Sound this opportunity presented the challenge of a lifetime". Robert Maicks – President Star Sound Technologies, LLC

Fueled by the passion for invention the team at Star Sound set out to procure the very first mechanically grounded room in all of audio. The thought of developing such a product has been instilled in us since the discovery of Sistrum Platforms in 2001. For years engineering has dreamed about inventing and constructing a world class sound room evolving a newfound technology for use in the structure of recording studios, modern day show environments and critical listening suites.

What if...?

you were listening to music in a room where all the vibrating walls, flooring and ceilings react the same to volume, frequency and dynamics and in unison?

there were no ninety degree angles to conflict with the laminar flow and movement of energy?

the room reduces or eliminates surface first reflection points?

the design could eliminate corner loading effects from all ninety degree intersections further managing detrimental acoustic energies?

the room was avoid of implemented acoustic traps or panels in order to "correct, modify or dictate and change" to the natural flows of energies and sound?

a ’live pressure zone’ of energy was encapsulated allowing for a natural speed and decay of resonance transferring through a continuously vibrating environment, connecting to the same acoustic, electrical and mechanical grounding plane?

What would this room sound like...?
