Description

A combined sound barrier

Technical field

The utility model relates to the technical field of sound barriers, specifically a combined sound barrier.

Background technique

Sound barriers are mainly used for sound insulation and noise reduction on roads, highways, 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 It is a more effective sound insulation method and refers to wall structures installed on the sides of railways and highways to reduce the impact of driving noise on nearby residents. A soundproof wall is also called a sound barrier. A facility is inserted between the sound source and the receiver to cause a significant additional attenuation of the sound wave propagation, thereby reducing the noise impact in a certain area where the receiver is located. Such a facility is called a sound barrier. Barriers are divided into traffic noise barriers, equipment noise attenuation noise barriers and industrial factory boundary noise barriers. Roads and expressways are the places where most types of sound barriers are used. The design of sound barriers has fully considered elevated highways, urban Wind load of light rail and subway, collision safety of traffic vehicles and all-weather open-air anti-corrosion issues. However, existing sound barriers usually use a layer of dense material as the sound insulation layer. The method is single and the noise reduction effect is not obvious. For this reason, we propose a Combined sound barrier.
