摘要: Abstract : A study was done in order to understand the acoustic resonance of narrow cylindrical tubes with side branch holes that are used photo-acoustic spectrometers. review available literature on subject lead an adaptation electrical transmission line matrix representation determine resonant frequencies tubes. Experiments were carried out PVC models actual spectrometer. The theory structures calculate frequencies. These compared experimental results.
