[0002] Since the traffic lines in my country's cities are generally dense, while facilitating travel, they also bring traffic noise to every corner, making road traffic noise pollution large in coverage and wide in scope. With the rapid economic development, the number of motor vehicles in my country has increased very fast, with a large number of vehicles and heavy traffic; at the same time, the more developed the city, the richer the nightlife, which makes the duration of traffic noise become very long. This has formed a state of ups and downs, leading to the aggravation of traffic noise pollution, which seriously affects the sound environment of surrounding residents.

[0003] The road noise reduction devices in the prior art mostly use sound barriers installed on both sides of the road to block noise. The long-distance sound barriers make driving feel oppressive and tiring, so a glass window is installed in the middle of the sound barrier, but transparent materials are prone to glare and reflection. Holes and grooves are opened through the plates of the sound barrier to enhance the sound absorption effect, but when the wind is strong, the wind passing through the holes and grooves will generate more noise, and the sound barrier only has a sound insulation and noise reduction effect, and cannot detect the noise of the current road. Utility Model Content

[0004] The purpose of the utility model is to provide a road noise monitoring and noise reduction device, which can block and eliminate the noise generated by road traffic through a sound barrier, reduce the noise, thereby improving the quality of life of surrounding residents, and suppress the reflection of glass windows on the sound barrier to improve driving safety.
