Title: Measurement workshop in Atlanta next month
Post by: Ivan Beaver on January 20, 2011, 07:54:16 pm
I hope this is an OK place to put this-feel free to move if needed.

This is just a heads up about a measurement workshop that in coming up on Sat. Feb 19th in Atlanta GA.

It is sponsered by the Atlanta chapter of AES.

There will be information up on their website shortly.  It is from 9am to 5pm

There are 3 presenters/talkers.

Charlie Hughes will be talking about the history of measurement systems-differences between different platforms and other cool stuff that is typically Charlie.

Wayne Lee will be talking about intelligability and how it is measured/different ways/different tools, prediction, importance and so forth.

I will be talking about actual measurements of both touring and installed systems.  I will have my multimic setup there.

There will be talks and demonstrations and lots of Q&A.

We will be both playing with the installed system and some portable stuff that I will bring.

We are still "putting it together" and are open to ideas from people of what they would like to see and be discussed.

Wow !

Great line up of presenters and it seems that you have quite a few of the bases covered, Ivan.

Any chance you guys could discuss capturing IR's using dodecs and/or balloons ?

For those of us who cannot get there, will this be recorded and available for free or a reasonable price ?

Good luck with this.

As you know, you really cannot even begin to cover a topic like this in a day.  So we are going to try and hit the highlights and introduce measurement to some people.

Wayne is going to talk about capturing IR's and post processing-and he was thinkng about using talking about the use of the house system and a dodec.  I don't know exactly where it will go.  Time is limited.  I assume Wayne will touch on acoustical measurements.

I am going to try and stay strickly on system alignment and some of the differences between the two worlds-touring and install.  The approaches are often very different-mainly due to time.

I am still trying to get my ideas all sorted out.

I don't know about video availability.  The facility has all the cameras and such-but that has not come up for discussion.  I will bring it up however.

There will be a minimal charge (should be less than $50-they are thinking around $35 for non members-for now anyway)-mainly to cover lunch and the cost of the venue tech guy.  None of us are being paid or being compensated.

It is the audio business after all.  We are in it for the love-not the money.

I just put that part in for people to realize this is a not for profit type of thing and is something we are doing to "give back" to some of the community and share ideas and hopefully "raise the bar" a small notch.

Now if I can just figure out what exactly what I am going to talk about :-\

Ivan -

How about demonstrating the effects of changing window sizes in windowed measurements?

Ivan - Glad to see the ATL chapter is active again. Years ago I dropped my AES membership because there seemed to be no activities in ATL and the Nashville chapter did not support ANY live audio whatsoever.

Hey Ivan,
Would it be possible to Stream it? Even a simple Skype connection would proberly do it. Would love to go if it was not on the other side of the planet... or at least the pond.

First let me say thanks for giving back and not charging big bucks for this, although you may change your tune in the future! Haha!
What I would like is for someone to concentrate on sorting out the digital skullduggery. I've been doing audio for 29 yrs. and I understand gain and ins and outs and how delay and arrival time differences can affect phase and how reflections can cause cancellation and I just need someone to help me get through the frustration fest of trying to get the digital stuff sorted out. Sheesh! Whats a dodec? I haven't needed any "baloons" lately. Now I do? What the...??? If someone could give a course on SMART and not have it digress in to a remedial school on acoustics, that would be nice. The laws of physics have not changed for a very long time and their are many wonderful books on acoustics and wave propagation but the digital user unfriendliness sometimes seems as endless as trying to find the edge of the universe! (end old soundman dinosaur rant)
HELP!
THANK YOU, Chuck.

That would be up to the AES guys.  I have nothing to do with that part of it.

We do plan on doing demonstrations on reflections and how measurement position affects them.

Dodecs are used to energize the room and measure for reflections, reverb time etc.

Don't use balloons unless they are properly calibrated.

Seriously tpopping the balloons is used as an impulse to measure room acoutics.

There are many different "sides" to digital.  From consoles to DSP's to differences between DSP parameters

Why does this forum contimue to screw up when I am typing.  It gets very hard see what you are doing and just hope I am typing the correct thing.

Oh well. so much for this post

So are starter pistols and yachting cannons, although less so in these days of heightened security.  Thankfully, modern technology also allows us some other techniques.  But speaker balloons to show are still very useful to visually represent the speaker pattern.

Peter Mapp had a typically, for Peter, very humorous presentation that included a section on balloons used as acoustic impulse sources.  As I recall, he tested, a bit tongue in cheek, how different pressures, methods of popping the balloons, colors (do they colour the sound?), etc. affected the actual impulse derived.

With some of the rooms I have been in lately only a pistol or cannon could get far enough above the noise floor.  It was an NC around 65!  Gonna be a fun job-NOT.

Another note of interest.  It looks like Tom Danley and Doug Jones will be attendance at the meeting.  Not for presentation-but for the final Q&A and conversations during breaks/lunch etc.  Ya know-when the REAL learning is going on  at these events.

Unless something changes (which I doubt), there will also be some guest "audio guys" (Tom Danley and Doug Jones) for the discussion sessions and for general "networking".   Both are always fun to talk to.

As Ivan has already mentioned Doug and Tom will be there but also there will be our new National Sales Manager Paul Giansante who most recently was the head of tour sound for Meyer Sound for the US and European markets. Before that Paul was with Turbosound for several years. We are very excited to have Paul joining the Danley team.

Would really like to go to this.  Would be cool if next time you could schedule it on a day that isn't my wife's birthday (a significant one too) when we both have the day off...

This is probably a one time event.

Maybe you should have called and told us what days you couldn't make it. ;D

I will be making the trip down from N.C. for this one.
It's not very often you get a day to soak up knowledge from some the best in the business
or for that matter not have a scheduling conflict.
Thank You to the AES ATL section for making this available during the slow part of the touring season
and providing excellent topics to be covered throughout the day.
