What are the acoustic properties of plastic outdoor rectangular tables in outdoor spaces?

Plastic outdoor rectangular tables are commonly used in open spaces like parks, patios, and cafes. Their acoustic properties play a role in how sound behaves in these environments. Unlike metal or wood, plastic tends to absorb less sound, leading to more reflection. This can cause echoes or increased noise levels in busy areas. However, the lightweight and hollow design of some plastic tables may slightly dampen vibrations. Factors like table thickness, surface texture, and surrounding objects also influence sound diffusion. For optimal acoustics, pairing plastic tables with sound-absorbing materials like fabric umbrellas or plants can help reduce unwanted noise.
