Revisiting Clowes Hall: Upgrades for Sound, Acoustics, Noise Performance


Date: Wednesday, January 20th, 2016. 6:45 PM

Location: Clowes Hall (Butler University campus, 46th Street) Indianapolis.

Parking: Plenty of parking is available in a brand new garage directly behind Clowes Hall and the Schrott Center. Enter off Sunset Ave. just north of 46th Street.

Entrance: Please enter via the northeast door (closest to the parking garage) – there will be a sign on door. We will meet on stage.

Note:  Start time for this meeting is 6:45 PM

Clowes Memorial Hall, celebrating 50 years, is a multi-purpose performing arts facility that serves Butler University and the greater Indianapolis community. It was once THE Indy Concert Hall and hosted Eric Clapton and Cream in 1967, as well as the ISO. Its programming has migrated over 50 years from symphonic originally, to more pop and road show use. This necessitated changes in acoustics and sound systems as a phased plan, now completed. Clowes Hall is now one of only a few performing arts centers in the region with a complete “LCR” (left/center/right) theatre sound system. It is optimized with acoustics driving the design. A new L-Acoustics array was specified and installed.

Our presenter will be David Wright of Wright Consulting Associates, now a part of a national engineering firm, KJWW Engineering Inc. David will review how design steps were prioritized with budgets and how acoustics were addressed before any sound system or product could be designed. If time allows, we also plan on doing a relative calibration for attendees’ SLM meters, as a field exercise. Bring your portable measuring mic and calibrators if you have one!

Our host at Clowes Hall will be Ernie Yezzi, Sound Technician/Technical Stage Crew.

Postal Recording Studio Tour – June 25, 2015



LOCATION:  1144 S Belmont Ave, Indianapolis, IN 46221

This was a rare opportunity to see a fully-functional analog and digital recording studio in operation.  Host Jake Robinson gave us a tour of Postal Recording and, with the assistance of some local musicians, provided an opportunity to compare the sound of analog and digital technologies.

Networking and Digital Audio Transports – July 23, 2015

DATE: RESCHEDULEDTHURSDAY, July 23, 2015. 7:00 – 9:00 PM

LOCATION:  Esco Communication, 8940 Vincennes Circle, Indianapolis, IN 46268

PRESENTER: Bradford Benn, Harmon Professional


During our next meeting, Bradford Benn will review and compare protocols and application examples for networking and digital audio transports. 

  • AES-3, AES-67, AVB, CobraNet, Dante, BLU, Qlan

** Please RSVP for this new date…even if you had RSVP’d earlier.  (RSVP is for head count only – the Meeting is free and open to all.)

He was heavily involved in the development of HiQnet System and Audio Architect™software, the evolution of the HiQnet™ protocol, and the development both of Ethernet AVB products and the protocol. He has been involved with such network intensive projects as City Center in Las Vegas, Lucas Oil Stadium, and the MetLife Stadium to name just a few. In addition to his responsibilities at Harman, Bradford serves as a co-instructor for the Syn-Aud-Con Digital training seminars as well as being an InfoComm University Adjunct Faculty Member. His dual-background in IT and audio has uniquely prepared him for this role. When he isn’t working, he can often be found behind a camera taking photographs.

Acoustics – Before & After Measurements with Gavin Haverstick

DATE: THURSDAY, March 26th at 7:00 PM

LOCATION:  Sweeney Chapel at Christian Theological Seminary – 1000 W. 42nd St., Indianapolis, IN 46208

DIRECTIONS: Christian Theological Seminary is located on the Northwest corner of 42nd Street and Haughey Avenue. Sweeney Chapel is on the East side of the campus near Haughey Avenue. There is a parking lot entrance off of Haughey Avenue just North of where the Chapel is located.  


The campus at Christian Theological Seminary has long been revered for its unique architecture. Indiana University Professor and former Art & Architecture Critic for The Indianapolis Star Steven Mannheimer calls it “Undoubtedly, the best modernist structure of this scale and contemplative purpose in the city, and among the finest in the nation.” The building was designed in 1966 by acclaimed architect, Edward Larrabee Barnes (1915-2004), who also designed the Indianapolis Museum of Art and the IUPUI University Library among other works around the country.

Sweeney Chapel was added to the building in 1987. While beautiful and distinct, the Chapel was not performing well acoustically for its main application – speaking engagements. Gavin Haverstick from Haverstick Designs was hired to conduct acoustical testing in the Chapel and to develop a plan to improve the acoustical performance of the space. The Reverberation Time (RT60) at 500 Hertz (Hz) was measured to be 4.06 seconds in the empty Chapel. This is not conducive to intelligible speech, so a plan was put together to improve the acoustics of the space while trying to retain the modern feel of the room – a delicate balance.  

Gavin Haverstick will present a case study of the project. We will go through testing data that illustrates the results before and after the acoustical improvements were made in the room. We will discuss the acoustical consulting process, testing data, predictions and the implementation of acoustical materials.

This is a great opportunity to see and hear a fantastic piece of architecture here in Indianapolis while going through the process of renovating an existing space to improve the acoustics of a venue of this size.

Howard L. Schrott Center for the Arts Tour

TOUR: Howard L. Schrott Center for the Arts


LOCATION:  Howard L. Schrott Center for the Arts at Butler University

DIRECTIONS: The Schrott Center is located on the Butler University campus at the corner of W. 46th Street & Sunset Avenue. It’s Bldg. 28 on this map: and here is a link to Google Maps:


Parking will be available in the lot immediately behind the Schrott Center (off Sunset Ave.).  There’s a lot of construction in the area – we will send out a reminder several days before in the event of any changes in road access or parking.

Our host and resident technical guru will be Dennis Long, Production Manager for the facility.  Dennis’ background includes years of experience in a theatrical performance facilities as well as a strong electronic engineering background in television and related areas.

Schrott Center was planned and designed to be primarily a classical performance hall (Clowes Hall is now accommodating many road shows).  We’ll take a tour throughout the facility, including access, HVAC, theatrical/performance support areas and various systems – lighting, sound, video, etc.

David Wright from Wright Consulting Associates is able to join us for a brief discussion of the acoustical aspects of the performance hall.  Wright Consulting Associates Inc. was hired by Butler University for electro-acoustics consulting.  WCA Inc. worked with Bonner & Associates from Texas for sound system design to integrate the architect’s variable acoustics approach for the room.  David will review room modeling, variable acoustics, room diffusion and how the sound system reacts to the acoustical design.

Pat Brown – September 10, 2014

LOCATION:  WFYI COMMUNITY ROOM (1630 N. Meridian St. Indianapolis, IN 46202)


TOPIC:  There are few things more confusing in the audio marketplace than amplifier and loudspeaker performance specifications. Their origins are often obscure. Their validity is often questioned. While the likelihood is high that there will someday be meaningful, universally-recognized Standards for these metrics, in the meantime audio engineers must specify and deploy loudspeakers and amplifiers. The “Common Formats” have addressed the problem by providing real-world, defensible methods determining key loudspeaker and amplifier metrics for use by sound system designers. The Common Loudspeaker Format (CLF) has become the most widely used data format for room modeling programs. The Common Amplifier Format (CAF) builds upon it. Together they give the sound system designer everything needed to deploy loudspeakers and amplifiers. Pat Brown will present the major tenets of each.
