How to Solve the Low-Frequency Resonance Caused by Accord Leading to Tinnitus?
1 Answers
The solution to the low-frequency resonance caused by the Accord leading to tinnitus is to install high-efficiency soundproofing cotton for noise reduction. Below are specific details about low-frequency resonance in cars: 1. When low-frequency resonance occurs in a car, the vehicle idles or drives at low speeds, and continuous low-frequency resonance inside the cabin causes discomfort to the driver and passengers, with severe cases even leading to dizziness, vertigo, and nausea. Due to the thin metal and plastic panels in mid-to-low-end cars, external noise can penetrate. Installing thickened soundproofing panels can block the noise. The car body's design inherently avoids overlapping the car's natural frequency with the engine's frequency. However, due to wear and tear from usage, the car's natural frequency changes, causing resonance at a new speed. 2. For low-frequency resonance in cars, it is recommended to use white sound-absorbing cotton (white cotton, Sherry cotton, microfiber cotton) for soundproofing materials, as it can effectively absorb low-frequency noise bands generated externally or internally. As for vibration damping panels, there are two types: asphalt and butyl rubber. Although both can eliminate low-frequency noise in cars, butyl rubber is preferred because asphalt vibration damping panels emit toxic gases such as formaldehyde and toluene at high temperatures, which significantly impact human health.
