Urban street noise is a pervasive issue, but could common planter boxes offer a solution? While not as effective as dedicated sound walls, strategically placed planter boxes with dense vegetation can contribute to a quieter environment. The soil, plants, and the structure itself absorb and deflect sound waves, particularly higher-frequency noises. For best results, use deep boxes filled with soil and plant dense, broad-leaf evergreens or tall grasses to maximize mass and surface area. Placing them as continuous barriers along property edges creates a more effective buffer. They work best in combination with other measures but add the dual benefit of greening the cityscape. Ultimately, urban planter boxes are a valuable tool in the green infrastructure toolkit, offering modest noise reduction while beautifying our streets.
