acoustic or sound power is the power radiated by a source
device over a time period. It is measured in Watts but
routinely reported as a sound power level in dBPWL with a
reference of 10**(?12) watt. the time period is usually the
period for a cycle at the frequency of interest. since
acoustic power represents the energy emitted by the source
rather than a received value, it is independent of
measurement distance and the environment. thus sound power
based EQ would account for only the frequency response of
the power emitted by the source and not the environment or
the directionality of the source.

it is NOT SPL.

And this is different from the CLF baloon measurements
referenced and linked below how?

And SPL measurements made with MLS measurement tools is not a
part of this measurement suite how?

And of course the OP's reference to his dude being the first
guy ever to measure and present this concept is correct how?

And measuring down to 100 Hz ,in room , is accomplished how?

Please enlighten me.



peace

This technology of generating an inverse curve of what
you measure in a real room has been around forever. This
is what we all thought was going to save our butts when
we got our first RTA and 1/3 octave EQ 30 years ago!
Yeah it can help for one spot ( like where the dude's
head singing into mic in

no. it is based on entirely different principle -
acoustic power response (APR), not SPL! there has not
been any software around to measure acoustic power
response before.

front of a monitor on the verge of feedback is) but as
far as actually fixing the acoustic
environment..............that is still a dream and I do
not believe this technology has anything new that has not
been tried over and over with a different name already.

Power response is just SPL averaged over some angles off
axis of on-axis. It is nothing new or special.

All the pros use these (
http://www.clfgroup.org/clfdocuments.htm ) kind of
manufacturer provided balloon files to tune the hanging
line arrays in concerts etc. Just how do you correct for a
speaker with an internal crossover in a room when all the
control you have is to modify the input to the left or
right channel of a monitor with a crossover in it.? Not the
same way you change the signals driving each individual
driver in a line array with perhaps 20 midrange and
tweeters in a known physical orientation per side and
pointing into the inside a venue described in AutoCAD and
loaded into the crossover itself .

It is so easy to fool the ear. Just think about it, every
time you hear a center image your brain is lying to you. I
usually think that people who found the "magic-bullet" have
no clue about how people listen to things they are hearing
and get fooled by this BS. Originally you said this ConMan
can measure to 10 Hz in a room.. That was what clued me in
to the fact that you've been had. I need go no further
than I would if your rant began with. "I found this
perpetual motion machine!" You can measure something at 10
Hz in a room but it aint only what is coming out of the
drivers, it is mostly just garbage. Anyone who is thinking
the last sentence is not 100% true is being fooled and
needs to cure their ignorance before they lay their money
down or they deserve to have their money removed from their
wallet and crap injected into their ears like the latest
generation who have been fooled into thinking that
McDonalds is good food and hundred dollar earbuds connected
to an Ipod sound like live music.

peace
dawg.

try.

IMHO ConEQ is another variety of snake oil being marketed
by another version of conMan to a new generation of ups.

try it!
