Description
Technical Field
The utility model relates to the technical field of sound insulation barriers, in particular to a photovoltaic sound insulation barrier.
Background
Sound barriers are devices which are known as sound barriers, which are designed to provide a significant additional attenuation of the sound wave propagation between the source and the receiver, thereby reducing the noise contribution in a certain area where the receiver is located.
When the sound wave meets the sound barrier in the process of propagation, three phenomena of reflection, transmission and diffraction can occur. Barriers are generally able to block the propagation of direct sound and provide sufficient attenuation of transmitted sound with negligible effect.
Therefore, the sound insulation effect of a sound barrier can be generally expressed by a noise reduction amount, which reflects the above-mentioned two shielding and sound transmission capabilities of the sound barrier. An acoustic barrier is inserted between the source and the receiver, the barrier being of infinite length so that sound waves can only diffract over the barrier to form an acoustic shadow zone behind it, as if the light were blocked by an object to form a shadow. In this shadow region, one may perceive that the noise is significantly reduced, which is the noise reduction effect of the sound barrier.
The sound barriers can be classified into the following categories according to the material: metal sound barriers (metal shutters, metal screen holes), concrete sound barriers (lightweight concrete, high-strength concrete), PC sound barriers, glass fiber reinforced plastic sound barriers, and the like. The different applications can be divided into the following categories: railway sound barriers, highway sound barriers, urban landscape sound barriers, residential area noise reduction sound barriers, and the like.

The existing sound insulation barrier only has sound insulation and noise reduction functions, has good social benefits, but cannot reflect economic benefits.
