What is the situation with Volvo resonance?

[GraceMarie]

Resonance refers to a humming sound inside the car when it reaches a certain speed range, and some Volvo models exhibit more noticeable resonance phenomena. Below is an introduction to resonance: 1. A car is composed of many components, and it is actually quite difficult to prevent these components from resonating while driving. Many luxury cars incorporate designs to prevent resonance in their chassis, such as rubber blocks on the chassis, which help mitigate resonance. If a car experiences resonance, it is generally difficult to repair. 2. Some cars may develop abnormal noises over time, typically in the chassis or interior. Interior panels are secured to the car body with clips, and these clips can loosen over time, causing the panels to produce abnormal noises when driving over bumpy roads or speed bumps. These noises are hard to resolve. 3. The chassis has many control arms, each equipped with rubber bushings. Rubber components can deteriorate over time, and when the rubber bushings age, the play between the control arms increases, leading to abnormal noises from the chassis when driving over bumpy roads or speed bumps.
