【Abstract】The noise generated bythe turbochargeris more significant under transient conditions.This typeof noise is moreeasilynoticedbythedriverandcancausedissatisfaction.Therefore，studying turbocharger noiseidentificationand transmissionpaths isof great importance forreducing itsnoise impact.Currently，there are various research methods for turbocharger intakenoise，including near-fieldsound pressurelevelranking，surfacevibration velocity method，enveloping separation method，acousticcameramethod，and structural transmission pathanalysis.This studyselects thestructural transmission path analysis method.The analysis resultsshowthat the main transmissionpathof airflow noiseis through air propagationratherthan structural propagation.This conclusion provides key guidance forsubsequentlyoptimizing and reducing the air propagation process of radiated noise.
