Product Introduction

Sound barriers are mainly used for sound insulation and noise reduction on roads, expressways, elevated composite roads and other noise sources. They are divided into reflective sound barriers that are pure sound insulation, and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method. It refers to wall structures installed beside railways and highways to reduce the impact of traffic noise on nearby residents.
Soundproof walls are also called sound barriers, which are divided into traffic soundproof barriers, equipment noise attenuation soundproof barriers, and industrial factory boundary soundproof barriers. Roads and highways are the places where most types of sound barriers are used.
