Art Noxon is a fully accredited Acoustical Engineer with Master of Science degrees in Mechanical Engineering/Acoustics and Physics. A Professional Engineer since 1982, he is licensed in Oregon to practice engineering in the public domain with the specialty area of acoustics. A prolific inventor, he developed and patented the iconic TubeTrap, the original corner-loaded bass trap/treble diffuser, 150 other acoustic devices, and counting. Lecturer, writer, and teacher of acoustics, he has presented 7 AES papers, numerous magazine articles, white papers and blogs. He is president of Acoustic Sciences Corporation, the company he founded in 1984.

BassTrap Sound-Off: FuzzBalls vs TubeTraps

Is a bass trap nothing more than just a container of fuzz, building insulation? Many budget bass traps are essentially just that; foam blocks, containers of building insulation. TubeTraps are different, they have a complicated mechanical structure inside, But are the complications worth the added cost?

Intelligibility - The Working Edge For Sound Contractors

Presented by Art Noxon at the 1993 NSCA Conference & Expo in Orlando Florida - Acoustic Alignment For Intelligibility.

Correlation Detection of Early Reflections (AES-1992)

Art Noxon

Presented at the 11th AES International Conference: Test and Measurement, this paper discusses incoherent and coherent reflections.

Sound Fusion and the Acoustic Presence Effect (AES-1990)

Art Noxon

Presented by Art Noxon at the 89th AES Convention, this paper introduces the free standing QSF version of Haas Saturated recording approaches the same subject from a generalized overview.

Articulation - Prerequisite to Performance (AES-1989)

Art Noxon

Presented by Art Noxon at the 87th AES Convention, this paper reviews the current of MTF test signals as the performance spec for hi-fi and pro sound playback rooms. The Modulation Transfer Function is the established basis for testing the quality of speech intelligibility.

Articulation and the Small Room (AES-1988)

Art Noxon

Presented at the 85th AES Convention, this paper was written in response to the difficulty in accounting for the satisfaction from the 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. This paper covers the details of MTF testing.

Controlled Reflection Isolation Booth (AES-1987)

Art Noxon

Presented by Art Noxon at the 83rd AES Convention, this paper discusses how 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. This paper introduces the concept of a sampling room, highly reflective with a fast RT60.

Room Acoustics and Low Frequency Damping (AES-1986)

Art Noxon

Presented by Art Noxon at the 81st AES Convention, this paper takes a look at how room modes are managed by corner bass traps.

Listening Room - Corner Loaded Bass Trap (AES-1985)

Art Noxon

Presented by Art Noxon at the 79th AES Convention, this paper discusses the physics behind how corner loaded bass traps work. It was written over 25 years ago, just as the ASC TubeTrap had recently been introduced for use in hi-fi audio. The idea of bass trapping was limited to recording studios at the time, and were huge and expensive boxes. However, the idea of corner loading with bass traps had never been considered and was a revolutionary concept at the time.
