Ripple Tank Story Reflection
Enjoy this week's inSIGHTful story from Art relating to the Ripple Tank project. Link to full thesis paper by ASC president and TubeTrap inventor, Art Noxon, PE Acoustical Blinded, had to listen During the summer of ‘72 while working on my master’s degree project, a high-end ripple tank, I temporarily blinded myself. [...]
The Ripple Tank Pt. 10
The Ripple Tank paper concludes! Link to full thesis paper by ASC president and TubeTrap inventor, Art Noxon, PE Acoustical Channel Filter Networks The uniform channel of infinite length is frequency indiscriminate. However, if its impedance at some point is abruptly changed, part of the input power is reflected back upstream. If [...]
The Ripple Tank pt. 9
The series continues! The Ripple Tank pt. 9! Link to full thesis paper by ASC president and TubeTrap inventor, Art Noxon, PE Acoustical Standing Wave Resonance The fundamental and higher harmonic resonant characteristics of a straight channel with blocked ends is easily accomplished with the water wave system. Its behavior is analogous [...]
The Ripple Tank pt. 8
The Ripple Tank series continues! Link to full thesis paper by ASC president and TubeTrap inventor, Art Noxon, PE Acoustical CHAPTER 4 Wave Channel System Distributed impedance occurs whenever one dimension of a wave system meets or exceeds 1/4 wavelength of the lowest applied frequency. Both the acoustical pipeline and wave [...]
Long, Narrow Hifi Room Set-up

The Ripple Tank Pt. 3
Chapter 2 Get ready for another snippet of an important thesis paper, by ASC founder, president and TubeTrap inventor, Art Noxon, PE Acoustical Analog Proofs The ability of the ripple tank system to model I acoustic and other wave type systems is generally acknowledged and is commonly used in most elementary physics [...]
The Ripple Tank Pt. 2
Synesthesia (layperson's narrow definition): seeing sound That is really the crux of the matter for this conversation: using your eyes to perceive what sound waves are doing in a room. This week we read a description of the mechanical apparatus used in this innovative approach to bridging the sensory divide that [...]
The Ripple Tank
Synesthesia: a sense impression experienced by one sense through stimulation of another sense Have you ever seemed to see a flash of red at the instant the violin section hits fortissimo? Or a haze of deep blue across your vision as the bassoons begin to harmonize? This happens for [...]
The Queen of Rock ‘n Roll
We were saddened to learn of the passing of the Queen of Rock 'n Roll, Tina Turner, this week. So, to honor her memory in some small way, we share this story from ASC founder, president and TubeTrap inventor, Art Noxon, PE Acoustical, in which her larger-than-life persona and singing talents played an [...]
Audio Room Optimization Myths
What do you do about a room that was simply not made for high-end audio reproduction? This week we explore some of the approaches people have taken, including the myths and the truth. In a few short weeks we will be setting up acoustic control systems in dozens of [...]
Speaker Positioning For Maximum Sound
What does this mean? Read on as ASC founder, president and TubeTrap inventor, Art Noxon, PE discusses speaker positioning for maximum sound – as featured in a five-part series by Art in Home Theater Magazine Ambience speakers are readily becoming standard in home theater As we survey audio systems [...]
Flutter Tones in Hifi & Home Theater pt. 3
