Reducing Pool Noise in a Courtyard: Plant Selection for Sound Absorption

Dense, Shiny-Leaved Plants Beat Palms for Noise Control

A Mexico condo complex with U-shaped buildings and a central pool suffers from noise bouncing off concrete walls. The question: will palms or flowering shrubs absorb sound?

Effective Sound-Absorbing Plants

Palms have sparse, non-shiny leaves—minimal effect. Instead, choose dense, shiny-leaved evergreens:

• Evergreen oak (Quercus virginiana types)
• Holly (Ilex spp.)
• Magnolia (M. grandiflora, M. ‘Little Gem’)

Key Principle

Density and leaf texture matter more than height. A thick hedge of hollies or magnolias at the wall line will absorb more sound than a row of palms. Plant as densely as space allows.
