【Abstract】Based on a customer feedback case of a certain vehicle model experiencing abnormal noise and howling during rapid acceleration in forward and reverse，this article introduces the process of troubleshooting and solving the abnormal noise in turbocharged intake. The analysis method of“source path acceptance”is used to eliminate the impact of related frequency noise using high-frequency mufflers. After multiple rounds of comparison and testing verification analysis，the optimal solution is confirmed and the problem is rectified.
