My Jade car is a sports city station wagon. It has good handling performance and decent comfort. It is light for a single body. The sand panel of the body is too thin and the noise generated during driving is very small. Too noisy.

The sources of noise are summarized below:

1: The tire noise is very loud when driving at 80mph

2: There is a low-frequency echo when sitting in the back seat< /p>

3: There is also the wind noise caused by the wind resistance when driving

The following are some solutions to reduce it, sound insulation construction

Front wheel fender construction, Reduce tire noise
