Visually, a Ruben’s tube showcases standing waves. When the speaker inputs sound into the tube, it creates pressure waves. At the right frequency (ie. The fundamental frequency or resonant frequency of the tube), high pressure peaks leaving the speaker will consistently meet up with a low pressure trough reflecting back from the closed end of… Continue reading How does it work?
Commissioned by Musarc, one of the UK’s most progressive choral ensembles, Kneebone and Suzuki teamed up to create this installation in St. Bartholomew The Great, London, United Kingdom. This visual system showcasing the relationship between soundwaves and sound pressure. The duo created two pieces for this installation: the first, Slash, has a machinery style sound to… Continue reading Case Study: Mathew Kneebone and Yuri Suzuki
Generally, Ruben’s tubes demonstrations utilise pure frequencies in order to generate the best possible standing wave. For my composition, I don’t want to be using generated tones based on frequency numbers, but rather work with instruments and play with different timbres. As a result, I’ve been testing the Ruben’s Tube with different musical instruments. Below… Continue reading Testing Timbres: Clarinet

Since I’m using LPG/Propane gas, the speed of sound in it is 258 m/s. (v) The length of my pipe is 2.4m. (L) Therefore, to calculate the wavelength, it will be: λ = 4L λ = 4*2.4 λ = 9.6 Therefore, the frequency will be: f = v/λ f = 258/9.6 f = 26.875 Now… Continue reading First Tube Frequencies: 2.4m
Calculating Standing Waves in an Open Tube: v=fλ where v = the speed of sound, f is the funadmental frequency, and λ is the wavelength. f=v/λ To calculate the wavelength: λ=2L Where L is the length of the tube in meters. To calculate the resonant frequencies for the length of the tube: f(n)=(n*v)/2L Where n… Continue reading Time to calculate!
