Acoustic resonance can cause high levels of vibrations leading to damage or premature failure of critical components. Although acoustic resonance affects a broad spectrum of industrial equipment, piping systems will be of focus in this work. Both passive and active damping techniques were previously investigated. However, there is a need to investigate the practicality of such devices when implemented in industrial systems. Herschel-Quincke (HQ) tubes have been selected for experimental study throughout this work. The experimental setup consists of an open-air loop pipeline system which is capable of exciting a standing wave with a fundamental frequency of 30 Hz and a target dominant fifth mode of 150 Hz. Transmission loss measurements were performed by means of the two source-location method. Insertion loss measurements were performed with a straight pipe used as the baseline. The current work has shown that Herschel-Quincke devices have potential for practical implementation into resonant piping systems in industry.enArticle
