What are the differences in sound absorption between WPC and foam-core outdoor tree boxes?

When comparing WPC (Wood-Plastic Composite) and foam-core outdoor tree boxes for sound absorption, several key differences emerge. WPC tree boxes, made from a blend of wood fibers and plastic, offer moderate sound absorption due to their dense structure. They are effective at dampening mid-range frequencies but may struggle with higher-pitched noises.

Foam-core tree boxes, on the other hand, are lightweight and excel at absorbing high-frequency sounds thanks to their porous material. However, they may lack the durability and structural integrity of WPC, especially in harsh outdoor conditions.

For urban landscaping projects, WPC is often preferred for its balance of sound absorption and longevity, while foam-core boxes may be suitable for temporary or low-traffic areas where high-frequency noise is the primary concern. The choice ultimately depends on the specific noise reduction needs and environmental factors of the installation site.
