How to Solve Car Resonance Noise?
2 Answers
Solutions for car resonance noise are as follows: 1. Change the cabin space: Open the car window, and this abnormal noise will be reduced. This alters the space volume and allows low-frequency noise to dissipate. Filling the car with items can also improve the situation. 2. Modify the vehicle body properties: This affects the propagation of sound waves. For example, Volkswagen models have less low-frequency resonance because their body cavities are wax-filled, significantly reducing resonance. Owners can install sound-absorbing materials to reduce noise. 3. Visit a 4S shop as soon as possible for a comprehensive inspection and adjustment of the car. Engine resonance involves integrated issues such as components, joint treatment, and tuning. Problematic vehicles should be inspected and repaired promptly.
That buzzing resonance sound in a car can be really annoying. When I encounter this issue, the first thing I check is the tires. Uneven tire pressure or small stones stuck in the wheel hub can cause resonance at specific speeds. I remember last time on the highway, the steering wheel was shaking—turned out the front wheel balancing weight had fallen off. After rebalancing, it was immediately quiet. Also, if the spare tire isn't secured tightly, it can knock rhythmically in the trunk, and checking this is effortless. If there's damage to the exhaust pipe or loose screws, that low-frequency rumble becomes more noticeable around 2000 RPM—just crouch down and shake the exhaust pipe to find the loose spot. If the cause still can't be found, consider the engine mount rubber aging. When this rubber component deteriorates, its damping effect weakens, and engine vibrations transmit into the cabin.
