Investigation of Turbocharger-Induced Whoosh Noise in a Vehicle 2020-01-5090
In this study, whoosh noise phenomenon was investigated. This broad-band noise is revealed during full throttle run-up maneuvers at high gears between 1000 and 2200 rpm and also during sudden closure of throttle. To investigate the root cause of whoosh noise phenomenon, airborne source quantification (ASQ) method, structural and cavity modal analyses, and CFD analysis were used. Then, a so-called A-tube resonator was designed, manufactured in prototype level, and mounted to turbocharger outlet duct. Finally, a solution was obtained both objectively and subjectively.
