What Causes the Loud Engine Noise in the Levin Hybrid?

[DiAnnie]

There are many reasons for loud engine noise, such as wear and tear of engine parts, aging of the muffler, poor lubrication system, excessive carbon buildup, etc., all of which can generate noise. By adding vibration damping panels along with sound-absorbing pads, road noise and tire noise from the engine can be effectively reduced. Below are the relevant explanations: 1. Road Noise and Tire Noise: Road noise and tire noise are caused by the friction between the tires and the road surface, leading to vibrations and noise. Therefore, vibration damping is the best solution. Comprehensive application of vibration damping panels or specialized damping panels, sound-absorbing pads, and door sealing strips to the fenders, floor, and doors can improve tire and road noise from three sources: vibration damping, sound absorption, and sound insulation. 2. Wind Noise: Wind noise occurs when the pressure of the wind exceeds the sealing resistance of the doors. Thus, enhancing the sealing resistance is the most direct and fundamental solution. Door sealing strips and inner sealing strips can effectively address this issue.
