These are the first two articles written by Art about room acoustics and corner bass traps. The first paper introduces the TubeTrap, shows how it is designed and how it is used in rooms. The second paper takes a look at how room modes are managed by corner bass traps.

These next two papers were written in response to the difficulty in accounting for the satisfaction from TubeTrap use when doing traditional, steady state room mode analysis, pink noise and tone sweep evaluation of room acoustics. Articulation accounted for the dynamic aspects of room acoustics. The first paper covers the details of MTF testing and the second paper looks at MTF as a global concept in performance spaces.

The next two papers are about acoustic spaces for recording. TubeTraps led recording engineers to discover that lots of very early reflections produce a better, more manageable sound than the traditional, reflection-free, dry studio recording. The first paper introduces the concept of a sampling room, highly reflective with a fast RT60. The second paper introduces the free standing QSF version of Haas Saturated recording approaches the same subject from a generalized overview.

This last AES paper by Mr. Noxon addresses the hot field of acoustic diffusion. It introduces the concept of coherent and incoherent diffusion, how to measure it and what each type is good and not good for.

Church Acoustics - Unnoticed Means a Successful Job | Download PDF Version

by Arthur M. Noxon, PE. Originally featured in Church & Worship Technology, March, 2008.

Usually, working with churches is pretty hard. But one day I got the dream call. It went something like this: Hi. We had some vandals start a fire and our church was smoke damaged. It was covered by insurance and the entire inside of the church needs to be removed and resurfaced. We figure we can use this money to do the acoustic job we always needed, and still get the painting done. So what do we do?

Auditorium Acoustics

by Arthur M. Noxon, PE. A four-part article originally featured in Church & Worship Technology, April-September, 2002.

The traditional church is half auditorium and half recital hall in design. It needs to clearly present speech and yet a few minutes later in the service it needs to support engaging congregation singing. A new style of church service has evolved. The emphasis is on understanding the sermon and less on congregational singing, it is the church auditorium. Here as a study series to better understand the design strategies behind church acoustics.

The Art of Church Acoustics

by Tim Bott. An article originally featured in Church & Worship Technology, March, 2004.

Faced with fire and smoke damage, the New Life Center in Springfield, Oregon approached ASC President Art Noxon and gave him a blank canvas to design an ideal acoustic space. The result is a beautiful looking - and sounding - sanctuary that provides acoustic zones for the praise band, choir, speaker cluster, mixing board, and congregation. Read about a great example of how ASC works with our clients to provide balanced acoustic solutions, custom-designed for the specific needs of the space.

A traditional cry space is common in many churches, but how often are they used? Art Noxon discusses the different ways to build a cry facility for children and families that can solve all of the necessary noise issues but still allow full participation in the worship community of the church.

BIG Church Acoustics

by Arthur M. Noxon, PE. Originally featured in Church & Worship Technology, October, 2001.

All too often, a church is built like a civic auditorium--big space and many seats--yet in the case of a large church, the building is expected to perform like a church. An auditorium is made for "auditing", or listening. A church is made for auditing and singing, therein lies the important difference. Most acoustic design projects, and churches are no exception, start with a budget and a vision. By the time the building committee is finished with a fully functional church, it will have allocated about 10 percent of the total building budget to the acoustics, and that does not include the sound system, wiring, the audio room or the sound equipment. The hope is, after all is said and done, that the church will actually sound like a church.

Voicing The Church

by Arthur M. Noxon, PE.

Anyone can run calculations and toss acoustics into a church Santcuary. However, voicing a church is a skilled art. The church wants to be bright yet clear sounding. This means we add as little acoustic material as possible and carefully position it so as to best control only the problem reflections.
