Meeting Report: Dinner at Shapiro’s Deli & A Tour of Lucas Oil Stadium

The Central Indiana Section of the Audio Engineering Society recently held its first summer meeting on June 26, 2012 with a near-record attendance of almost 30 members! The first part of the meeting featured dinner hosted at Shapiro’s Deli courtesy of the Section for members which was certainly a hit with everyone in attendance, followed by a tour of Lucas Oil Stadium.

That’s right, dinner and a tour! The tour was courtesy of the Lucas Oil Stadium Sound & Lighting Department’s very own Floyd Paulsen with assistance from systems integrator and friend of the Central Indiana Section ESCO Communications.

Floyd took the section on a compressive tour of the stadium, including the field level where he discussed the complex system of speaker arrays and delays in the bowl, one of the amazing amplifier rack rooms, the press box, and the video and audio production suites. Along the way the section also received demonstrations of the Media Matrix and Crown Hi-Q operating systems which were in use throughout the installation.

The meeting was absolutely a must-attend for anyone interested in live production and installed sound and we are very thankful to Floyd, Lucas Oil Stadium Sound & Lighting, and ESCO Communications for their generosity and support of the section. Those interested can find a digital version of the handout distributed at the meeting here on ESCO Communications website.

Meeting Report – March 2012 – Central Indiana Audio Student Workshop

On March 10, 2012 the Central Indiana Section of the Audio Engineering Society hosted the first annual Central Indiana Audio Student Workshop. The event was hosted by Section Chair Kyle P. Snyder, as well as assistant workshop host Jeffrey Seitz and with great assistance from the Executive Board of the Central Indiana Section, in the Music Media Production and Industry studios on the campus of Ball State University.

Like other regional events, the Central Indiana Audio Student Workshop was modeled like a mini-convention. Our goal was to provide an intimate learning environment, open to anyone interested in audio, including local professionals, university students, and high school students. The Workshop provided attendees the opportunity to improve their skills with some of the best in the business, who presented on topics in recording, mixing, live sound, and acoustics.

We also wanted to provide the Workshop free of charge, to give students of all means equal access to the audio instruction we were providing. Also, not only did we want to provide high-quality instruction for free, but also we wanted to incentivize attendance with useful giveaways from sponsors. Finally, we wanted to ensure that an acceptable student to teacher ratio was achieved, so that students felt less like they were part of a crowd and more like they were in a small classroom where they could ask questions.

Our pre-registration topped out at 180, and we saw physical attendance at 150 including numerous walk-in’s, reaching a group of audio students and professionals from every corner of the state and many from neighboring territories, who were appreciative beyond words. We couldn’t have been more pleased with how the event turned out.

Following the comprehensive presentation, students led groups of the Section on tours of the performance hall prior to La Bohème’s first run-out, providing members the opportunity to view microphone positions as well as the video and audio production booths.

Members were provided the opportunity to watch the first act of La Bohème from the hall or the video / audio booths which allowed for ample time to ask questions of production staff.

Those interested are encouraged to view the live stream of La Bohème, November 11 & 12, 2011, at 8pm EDT.

He also explained how the recording industry began and how it has changed through the years from small special interest studios to mega studios which have now essentially regressed to boutique recording studio.

Additionally, he discussed the changes in the music business caused by digital downloads and the way the industry has reacted it.

He also discussed a variety of intellectual property issues which are pertinent to everyday engineers, specifically what engineers need to be mindful of in contracts as well as “fair use”, the making of demos, and so much more

Meeting Report & Recording – May 2011 – Dr. Uwe J. Hansen on Phase Considerations in Signal Processing

At this, the third of our meetings scheduled for the year which was held on May 12th, 2011 at 7pm, we were privileged to have Dr. Uwe J. Hansen speak on Phase Considerations in Signal Processing.

Dr. Hansen is Professor Emeritus of Physics at Indiana State University and a fellow of the Acoustical Society of America, among numerous other distinctions.

In his presentation, Dr. Hansen discussed how phase comparison can be a powerful tool with countless real-world applications. The three specific applications of phase related signal processing techniques discussed were phase sensitive detection, optical holography, and modal analysis.

Dr. Hansen explained that the elements essential to describing a monochromatic wave are amplitude, frequency, wavelength, speed of propagation, polarization and phase.

Additionally, it was explained that phase identifies the location of a point along the propagating waves and that absolute phase measurements are not only difficult but generally not of interest.

Meeting Report & Recording – March 2011 – John Murray And The 2010 NFPA 72 Fire Code

At this, the second of our meetings scheduled for the year which was held on March 17th, 2011 at 7pm, we were privileged to have John Murray speak on the new 2010 NFPA 72 fire code.

John has been an Audio Engineering Society member since 1980, is the principal and founder of Optimum System Solutions, and has seen a distinguished 30+ year career within the industry.

A small but enthusiastic group was present at this meeting, which opened with brief introductions and announcements, moving directly to the presentation.

In his presentation, John discussed the new NFPA-72 regulations and how they relate to speech intelligibility and therefore to STI measurements. He explained how these measurements and the achievement of good speech intelligibility are necessary to meet the new regulations. John also demonstrated the process of measuring and evaluating STI in several spaces to show what is required and what measurements are required to pass the new code.

Another topic discussed were the various types of systems described within the code and what requirements regarding UL certified equipment and speech intelligibility would apply, and why this code change was an opportunity for contractors.

It was indicated that the new code imposes certain responsibilities upon those same contractors to design and install systems which would meet the new requirements. This means that the contractors will need to learn more about STI and testing in order to properly design and install projects to meet the new requirements.

The meeting was brought to us courtesy of Renkus-Heinz, Inc. and McFadden Sales., and our thanks go out to ESCO Communications for the continued use of their facilities.

With this meeting we’ve continued our initiative of recording events for archival purposes and to allow for participation from members unable to travel. The recording from this meeting is available below for playback. As well, those who are so inclined can also download the recording for playback in their audio program of choice. Our apologies in advance for the somewhat boomy nature of the recording.
