Saratoga Springs High School Acoustic Design

Beautifully repurposed cafeteria


In response to some very positive compliments concerning our cafeteria acoustic design at Saratoga Springs High School, we thought we would share that project news with you.

Cafeterias are tough, as we explained previously in  “Help, I Work In A Cafeteria and I’m Going Deaf!” .  Truly, cafeteria space is one of the worst when it comes to conquering the acoustics. Think “tin can.”  




This space at Saratoga Springs High School started out as a repurposed gym/classroom, converted into a large upscale cafeteria.

Our scope of work was to acoustically compare the existing condition to the architect’s intended design. Their plan was a change for the better but, after modeling the space, we made recommendations that would step up those improvements beyond the original goal, while still preserving the look. We added K13 FC roof deck treatment above the new ceiling clouds, as well as changing wall materials and cloud materials. The school is very pleased with the results.

Massena High School – Not the Typical High School Theater Program!

In June of 2020 we were invited to tour Massena High School, located on the St. Lawrence Seaway, for an evaluation of their auditorium with future renovations in mind.

Auditorium seating

  As we arrived at the school and crossed the threshold of the facility, we were stunned to see elaborate 3D sets with staircases intertwined throughout, beckoning audiences to enter the riveting tale of “West Side Story.”  There was no doubt that Massena High School’s productions are top quality and out of the norm. This was not the typical high school theater program!

While they had some recently installed equipment in the room, most of the gear was getting old and needed to be replaced. The room itself was also aged and acoustically lacking.  Our goal was to elevate the sound, lighting and video quality to an excellence that matches that of their shows. Working with the architect, The IBI Group, we developed an innovative plan incorporating expanded capabilities including new catwalks, state-of-the-art LED lighting systems, new audio systems, new video systems, video production systems, and completely new controls. In terms of consoles and other peripherals, the renovation is now complete and is a truly impressive makeover of the space.

new controls

Some of the most noticeable changes are in a place that few people see:  the controls side of the room. There is an addition of an Allen and Heath D Live Series console and a new ETC Hog lighting console. Black Magic video controls, as well as higher-end Black Magic cameras, elevate this room technologically making a dramatic improvement over what they previously had.  All of the lighting has been upgraded to Electronic Theater Controls (ETC.)

  camera Every stage lighting fixture in the room has been replaced with LED color changing fixtures from Electronic Theater Controls, High End Systems and Varulite. Every fixture is now on relay-controlled power, which automatically shuts them off when they are not in use, thus extending their lives.

video screens in auditorium

The video systems are very impressive. Three 4k HD-enabled video screens are situated at the front of the room. They can be fed signals from broadcast production systems or a variety of computer sources.

You know, we seldom get to attend live productions after our work is done, but this is one school we wish were nearer our hometown. It would be nice to be in the audience enjoying the sights, sounds and experiences enhanced by our designs.  If you get to do that, let us know!

Inside the Egg - the auditorium

Canterbury Woods Performing Arts Center

The newly opened Canterbury Woods Performing Arts Center is part of an extremely busy senior citizens community in the Buffalo, New York area. This distinctive facility can offer a broad variety of live shows to their residents far beyond what they were able to do in the past. Formerly, they did not have a true performing arts space of their own, limiting what was possible. The design objective was to provide them with a much more flexible high-tech performance space thus enabling them to bring in more interesting shows.

Canterbury Woods Performing Arts Center "The Egg"


If you hear someone say that this space is masterful, believe them! During the design-phase of the project, we affectionately called it “The Egg” inspired by the unique shape devised by the architect. At first glance, The Egg was going to be difficult to work with but we did and the end result has proven to be truly spectacular!


Auditorium at Canterbury


Acoustically, the challenge was to not allow the curves to generate echoes and other focused sound effects within the room. This was done with a variety of acoustically diffusive hard panels on the sidewalls and absorptive panels on the rear walls, working in conjunction with ceiling clouds to prevent focused energy and provide a good speech intelligibility into the seating area.


The room is comprised of several types of systems: 

  • Audio: In order to be user friendly for the visiting performance groups, we incorporated a versatile digital audio setup with the capability of bringing in analog audio consoles and/or guest digital consoles that can tie in directly to the systems. Now any group coming in can use the in-house Allen and Heath systems, or it will work for them to be able to use their own.
  • Lighting: This is all LED color changing and incorporates a variety of fixtures for a variety of purposes.
  • Rigging: There is a dead-hung stage rigging system, including a motorized main curtain that closes across the curved front of the stage.
  • Video: The room incorporates high-definition video projection, cameras, and other systems.


All of the systems are expandable. The original design incorporated a larger inventory of virtually everything, but budgets are budgets and we had to get it operating at a much lower cost. That is the mark of a quality theater consultant, if we do say so ourselves. We strive to get the best for our clients within necessary budgetary constraints.   The final result has been the creation of an enormously enjoyable performing arts venue!     Go over to their website and take a look!   Canterbury Woods Performing Arts Center

WXXI Audio Production 225

WXXI TV reached out to AVL Designs Inc. to design the interior acoustics and assist with noise control in their product 225 control room. They had recently purchased an AVID S4 Yukon console for the suite and wanted a control room that provided a better mix environment.

WXXI production suite

  LIMITED HEIGHT The space is an unusual shape with some features that cannot be changed. The oddly trapezoid room with one glass door to the side of the mix position, and a large window to the live room that could not be relocated, was limited in height. It also had an electrical panel that could not be covered for code reasons.

WXXI Production Suite

NOISE The first order of business was HVAC noise control. The background in the space was NC 40+. Ductwork design was what you see in office spaces, not studios. Working with their mechanical contractor we determined to enlarge ducts, change diffusors, move VAV’s, and control velocities.  The result ticks in at NC20.

WXXI Audio Production Studio


LAYOUT The new space was to have a mix position and a client listening position in the rear of the space, where it narrows considerably in a “V”. To even out response, we determined to use high order quadratic diffusors on the back wall. An electrical panel presented a problem. It could not move and had to be accessible. Some of the broadband quadratic diffusors were designed into a custom designed rolling cart. This allows them to go over the electrical panel but be legal as they could be moved. This allowed matching the rear sides of the space with broadband diffusion. GUD high frequency diffusors on side walls and the ceiling over the mix position to enlarge the mix image area back to the client desk. The sound at the client desk is just as linear and only down in level by 3dB from the main mix position. All products were from Real Acoustix LLC. Due to the door location and the “V” in the rear of the room, typical placements for bass traps were negated. We decided to use bass traps within the celling system, a bit unusual but it worked. Overall response is very linear, and only two subtle filters were used to final tune the Rogers LS3 main speakers.

Liverpool CSD

Liverpool Central School District

AVL Designs Inc. first became involved with the Liverpool Central School District in 2007. We were asked to investigate echo problems in their auditorium. When someone would play a snare drum or any other percussive instrument on the stage, you could hear 7 to 12 discrete echoes that were hard to miss. It was like bang…… bang, bang, bang, bang, bang, bang, bang. Of course, this was a problem. The echo occurred in certain areas of the room, not every area of the room, but it was so noticeable that this defect got in the way of most musical performances.

We corrected this by testing the space and then placing specific acoustical panels on sections of ceilings and side walls, effectively eliminating those echoes. When you add absorption to a room, you lose some of the liveness. It is an inevitable trade off when getting rid of the echoes. You lose some of the reverberation. 

In the process of time, we talked with the school district about other corrections that were available in the realm of electronic acoustics, which we have done successfully for other schools. After meeting with the music department, we decided to implement an electronic acoustic system in the space. Due to budget constraints, it was ceiling installation only. No side walls, no stage shell, but it was designed to allow a much more immersive sound quality for certain kinds of music.

The room was lacking low frequency response. The reverb time was around one second in the midrange, and it needed the ability to go to higher reverberation times for certain styles of music and types of theatrical performances. Once the system was installed, the school was thrilled. They were so enthused about it that they became a major proponent of this technology, sharing their experience with other schools we met with in the future.

As 2016 arrived, a major renovation was planned for the Liverpool Schools. They were enlarging the entire auditorium, refurbing the music department and adding some additional rehearsal spaces. As a result of our prior experience and success with their existing auditorium, AVL Designs Inc. was brought in along with the architect, on the early stages of this project.

Electronic Acoustics added almost everywhere.

There were a number of goals for the project, the first of which was to include electronic acoustics in many locations. It would not only be the in the auditorium and on the stage, but also in the large rehearsal rooms for orchestra, band and choral ensembles.  That way the singers and musicians would be able to rehearse in environments similar to what they would experience in the auditorium.

Electronic Acoustics Explained VIDEO

So, that became the initial driving force for the acoustical design. We had to look at how to treat the main auditorium to get the reverb time low enough and flat enough that when we implement the electronic acoustics, there will not be significant problems with frequency balance and reverberation curves.

The electronic acoustics system is based on Yamaha acoustic field correction devices. It is implemented with speakers located onstage, in overhead ceilings, in under-balcony ceilings, and on sidewalls. These systems are providing reverberation as well as early reflection support for the room. The system can also add voice lift to allow for events without sound reinforcement.

Bigger auditorium, curved walls and NEW balcony.

The auditorium was being dramatically enlarged, shaped with curved walls plus adding a balcony. To deal with that condition we developed a custom absorptive diffusive wall treatment. It consists of series of wells of different depths with perforated materials and solid materials, creating a diffuse sound field within the auditorium and generating a relatively low reverberation time for the size of the room. This design criteria was also used for the music spaces to produce similar reverberation curves for their base conditions. That way, when the electronic systems are commissioned, there will be tunings for each space that will mimic each other to the degree that you can mimic a smaller space to a larger space. In addition to the electronic acoustics and physical acoustic designs for this auditorium, AVL Designs Inc. was contracted for stage rigging, theatrical and house lighting, and sound and video in the space.

Huge Speakers? Here’s why …

One of the unusual features of the room is the incorporation of Danley Jericho loudspeakers. The Jerichos look huge and indeed are huge, but they are actually a replacement for line array technology that many auditoriums would implement, at a lower cost and a higher performance level. The Jericho combines a large number of drivers in a single large enclosure, creating an output pattern and sound pressure capability similar to a 12 element tall, mid to large scale line array.

Admittedly, it looks a little odd to have boxes this big in a high school auditorium however the pattern control over the wide frequency range of the speaker allows it to cover most of the main floor as well as the balcony without the need for other devices.


*We did, however, install over and under-balcony delay fill speakers. This was primarily for potential special effects for theater use, and also to add the few frequencies that would be missing as you go by distance to the back of the room.


The audio system is being fitted with an Allen and Heath D Live console, which is a substitute for a Yamaha console originally specified. (Due to Covid issues the Yamaha console is not currently available) The D Live is a great console and will do a fantastic job for the school in the new application.

Theatrical lighting consists primarily of Electronic Theater Control products and High End systems, with some Strand and Phillips fixtures as well.

Stage rigging is a combination of Brick House counterweights and Electronic Theater Controls Prodigy hoists.  The Prodigy hoists are used for onstage electrics, as well as a front of house moving head electric.  

All of the music rooms are used as green rooms, so we have a combination of intercom, call lights, and video feeds to each of those spaces from the main auditorium.

Quite a few of these systems are not fully online due to product availability problems in the current post-Covid world that we are living in. We hope to get all of them online toward the end of the year. The owner is very impressed with the space currently. They will be really excited when all of the final details are worked out. The transformation from the original room to what it is now is dramatic.
