What are the measures to reduce noise?

[Lynne]

Measures to reduce noise are as follows: 1. Tire noise: Every vehicle has tire noise, but the level varies. Tire noise is generally caused by air flow through the gaps in the tire tread pattern, creating air noise. Since tires are made of rubber, they tend to harden and age over time, leading to increased noise. New tires have better elasticity, offering improved noise reduction and comfort. If tire noise is excessive, check for tire aging and consider replacing them with more comfortable tires. 2. Wind noise: Like tire noise, every vehicle experiences wind noise, which can be categorized into several types. One type is caused by pressure changes due to airflow separation around the vehicle body. Another is wind leakage or suction noise, resulting from air entering through gaps in the cabin and body, interacting with the surrounding airflow. The third type includes other noises, such as cavity resonance. Wind noise increases with higher driving speeds. Installing additional sealing strips can help reduce wind noise.
