Do Hedges Actually Reduce Street Noise?

Honest answer first: a hedge is not a soundwall. Measured reductions from dense vegetation are modest on the decibel meter. And yet clients consistently report their yards feel dramatically quieter behind a hedge. Both things are true.

What's actually happening

Dense foliage scatters and absorbs the high-frequency components of noise — the hiss and edge of tire and voice sound — while masking the rest under leaf rustle. Just as important, blocking the sight of the street changes how the brain processes its sound. Perceived loudness drops far more than the meter does.

Maximizing the effect

Density beats height for acoustics: ficus and privet, sheared tight, ground-to-top with no gaps. Depth helps — a hedge in front of an existing wall or fence outperforms either alone. For a busy-street property, that hedge-plus-wall sandwich is the professional move.
