ABSTRACT:
The application of the Herschel-Quincke (HQ) tube concept as a noise reduction device is
employed to reduce the noise of an industrial burner-combustor test rig. A computational
technique is developed to design the HQ tube dimensions to control the sound field in such
system. Transmission loss predictions from the analytical model are shown to correlate well
with experimental data acquired from an extended impedance tube setup, as well as the real
test rig. In addition, the frequencies at which maximum attenuation will occur are
determined.
