What are the differences in sound absorption between concrete and granite outdoor planters?

When choosing outdoor planters, material plays a key role not only in aesthetics but also in functionality, including sound absorption. Concrete and granite are two popular choices, but they differ significantly in their ability to absorb sound.

Concrete planters have a porous surface, which allows them to absorb some ambient noise, making them a better option for reducing echoes in open spaces. However, their sound absorption is limited compared to softer materials.

Granite, on the other hand, is denser and less porous, reflecting sound rather than absorbing it. This makes granite planters less effective for noise reduction but more durable in harsh weather conditions.

For those prioritizing noise control, concrete planters may be the better choice, while granite excels in longevity and minimal maintenance. Consider your needs to decide which material suits your outdoor space best.
