Project Title: Development of an Adaptive Helmholtz Resonator for Industrial Exhaust Stacks
Sarabjeet Singh, Carl Howard
|
The aim of this study is to design an Adaptive Helmholtz Resonator (AHR), which when fixed on the exhaust duct attenuates the fan and blower noise within the frequency range of 180 Hz to 350 Hz. An AHR has a variable resonance frequency that is achieved by altering its physical dimensions such as the cavity volume or neck length or neck cross- sectional area by the help of a control system, in order to track the changing frequencies of the noise.
