Does the Accord's Low-Frequency Resonance Cause Tinnitus?
1 Answers
Accord's low-frequency resonance causing tinnitus can be resolved by installing high-efficiency soundproofing cotton for noise reduction. Below are specific details about automotive low-frequency resonance: 1. During vehicle idling or low-speed driving: Continuous low-frequency resonance inside the car causes discomfort to passengers. Since external noise enters, installing thickened soundproofing panels can block the noise. The vehicle body design inherently ensures that the car's natural frequency is separated from the engine frequency. However, due to various reasons such as wear and tear from usage, the car's natural frequency changes, leading to resonance at a new speed. 2. Regarding soundproofing materials: Use white acoustic foam and damping plates, which come in two types: asphalt and butyl rubber. It is best to choose butyl rubber because asphalt damping plates emit toxic gases at high temperatures, significantly impacting human health.
