[big snip of assertions and opinions]

Meausrements... yes, I have data. What is your specific question?

Provide the specific measurements (and how you did them) that back up
the specific assertions you make above. We could then decide if your
views are supported by measurements you (or others) have made, nor
not.

Who is "we"?

This is usenet, and these postings are going to a number of groups.
Chances
are you and I aren't the only people reading this. Surprised if you
didn't
know this. Or is your question purely a debating tactic?

You don't speak for anyone but yourself, Lesurf.

Ah,you seem to have adopted the 'Go for the man, not the ball' debating
tactic. And employed the tone of 'Headmaster telling off the naughty
schoolboy who dared to ask impertinent questions'. :-)

...or as just a debating tactic to cover for not actually answering my
questions and providing the measurements you say you have. Is the idea
now to try and get a personal argument going to smokescreen that? :-)

Since my background is in science and engineering,

There are ZERO qualifications, not even a Drivers License, for someone
to call themselves a "Engineer". What kind of formal education in
engineering do you have... undergraduate/graduate and in what field?

Ah, yes. Looks like you do prefer "go for the man not the ball" instead
of
dealing with the substance.

You seem to overlooked that you haven't yet provided any measurements or
details of how you obtained them. Lacking that, how could anyone else say
if a given background would be appropriate to judge what you did? And the
point of my "we" above was that once you 'publish' your data every/any
individual reading this could make up their own mind about your
assertions
without having to take either me or you as an 'expert'.

I'm not bothered if you doubt I am 'qualified' or not. Nor if someone
else
has doubts. In physical science and engineering, people decide on the
evidence, not on the basis of simply accepting that someone is
'qualified'
so must be right. I just wanted to see what evidence you could offer for
your assertions and claims.

BTW Note that you introduced "qualifications" as if they were a test of
some kind. Not me. Then snipped the explaination I gave for why I was
saying what I was. Although if you want to call me 'Lesurf' you could be
more accurate and call me 'Dr Lesurf' purely for the sake of form. :-)
Maybe even put letters like IEEE and AES somewhere after my name, I
guess.
But I agree with you that 'Dr' in front of my name, etc, doesn't ensure I
could judge your measurements. Hence I don't normally use the 'Dr', etc,
as
it seems irrelevant. Particularly when there are no presented
measurements
to actually consider. :-)

I'm quite happy to leave others reading this to make up their own mind on
the basis of what you've said, and how you have responded. That should
set
your mind at rest if you fear I might lack the required 'qualifications'
you would demand for anyone who dared to examine your measurements in a
critical manner. :-)

I do tend to prefer to base my own conclusions on being able to assess
measured evidence, and the details of how those measurements were
obtained.

I understand. I've run about 23 batches of tests, as I recall, several
years back. If I have time I'll post something.

Look forwards to it. :-) Please post the announcement in all the groups
this is going to if you wish everyone reading your assertions to be able
to
make up their own minds and decide for themselves if your measurements
actually support what you have claimed.

Given that consumer audio is awash with 'technobabble' I tend to place
more reliance on that than on simply accepting assertions.

You enjoy intellectualizing but it would behoove you to get off your
penguin butt and do the work yourself.

Thanks for your help. Your response does help me make an interim
assessment
of your assertions whilst I await any evidence you eventually produce.

Slainte,

Jim

Sorry, didn't mean to post twice - still failing to get to grips with Vista,

Really? Would you care to explain that to my daughter, who gained her
degree in Mechanical Engineering from Coventry a few years ago? Or her
grandfather, who did the same degree (different Uni - I think Oxbridge,
but can't remember - it was pre-war) and among other things
certificated the Olympus engines fitted to Concorde but to the end of
his days was happy to describe himself as an "engineer"?

Zero qualifications? I don't think so.

I think there's 'qualifications', and 'qualified'.

Personally, I don't think having an academic degree necessarily
qualifies someone as anything. Doing/building/designing (etc) does. Not
sure what your daughter would say - I suspect she might agree.

And qualifications are not required to gain chartered engineering status
in a number of fields - they certainly help, though. Whether that means
they're any good is a different matter altogether.

And and and, you can call yourself whatever you want - don't make it so
though :-)

Well of course chartered status is a qualification in itself, but I am not
aware of any body that will award chartered status without the candidate
already having appropriate academic qualifications. Perhaps you can
elaborate if you believe otherwise.

Not anything, certain job titles, such as "architect" are reserved to those
with appropriate qualifications. Though I agree that the term "engineer"
isn't one of them.

Define your terms.

someone as anything. Doing/building/designing (etc) does. Not sure what

Ah - "I qualified in the University of Life". I think that my daughter
would agree that a few years waving a spanner or a soldering iron around
doesn't make up for a decent academic background in the fundamentals. Of
course, you'd have to ask her.

And qualifications are not required to gain chartered engineering status

Really? What fields? University of Eastern Florida comes to mind....

Sure, I can call myself "Reverend" or "Lord". As you say, don't make it
so. But a decent degree from a recognised university followed by practical
experience makes it more likely that you can achieve some sort of career.

Allthough the sonic effects of spikes may vary from speaker to speaker
and from room to room, they do move the resonnance of the
speaker-floor combo up in frequency. Sometimes it improves overall
sound, sometimes it doesn't. But the effects have a very natural
explanation.

Care to explain the mechanism that causes the resonant frequency to move
up?

FWIW I decided not to comment on the bulk of the items asserted most
recently as I didn't want to widen the issues. But a number of questions
like the above did occur to me. The problem is that with no measurements,
details of experimental arrangements, etc, it is often hard to assess the
assertions people make.

I believe that Mr. Powell is a troll. However, I do suggest looking at
the following:

1. A system with two masses, one very large and one very small, which are
loosely coupled by a flexible joint.

2. A system with two masses, one very large and one very small, which are
more tightly coupled.

If the masses are the same in these two examples, and you look at the response
to excitation of the smaller mass, what happens to the main resonance as the
coupling is increased? Hint: both the resonant frequency and the Q are
changed.

This stuff is easy to model as a two mass spring system, in the simplest cases.

Here in Virginia, these people could not legally call themselves engineers
unless they have passed the PE examination. The PE exam is fairly difficult.
In some other places, anyone can call themself an engineer, no matter what
kind of education and experience they ahve.

Places differ.

It's been my experience that the guy pushing faders is generically
called the "sound engineer," and that is fully interchangeable in common
usage with "sound man" or "sound guy."

Thanks for bringing that to my attention. I won't be making that mistake
again.

To be honest, I don't know why I didn't think about that before. I don't
call my professors "Doctor" unless they've earned that degree.

Yes, this is not legal in Virginia. The Society of Broadcast Engineers is
currently petitioning the state to make an SBE certification or an old FCC
First Phone License a legal identification to call yourself a broadcast
engineer, however.

I have had folks get into big trouble with it when bidding for state
contracts.

"You can call me doctor, but you'd be wrong because I have a Master's
degree. You can call me professor but you'd be wrong there too because
I'm a lecturer. So call me Colonel."
