WebApr 28, 2024 · The corrugated tube as an effective medium. In this section, the propagation in the corrugated tube is described by an effective medium. A simple way for that is to consider the transfer matrix T linking the downstream waves (p 2 + and p 2 −) to the upstream waves (p 1 + and p 1 −): (2) p 2 + p 2 − = T 11 T 12 T 21 T 22 p 1 + p 1 −. WebTranscribed image text: [C] A corrugahorn is a corrugated tube which is spun around to make a sound. Data: speed of sound = 344 m/s density of air = 1.29 [kg/m] (1) Given such a tube with a length of 1.00 meter, what are the resonant frequencies for a tube of this length? (It's open at both ends).

WebSinging corrugated pipes provide an excellent way to captivate the student's imagination. 1 When you swing the flexible corrugated tube around your head, a loud and clear tone is produced. If you whirl it faster, it jumps to higher tones. It is a great way to demonstrate harmonics using sound. However, there are some interesting subtle prob WebMay 22, 2024 · The distance between two wave crests is the pitch and the height of the wave the volume. Anything that can disrupt or absorb the wave will help reduce the sound. Corrugated cardboard is good for soundproofing.
