🔇 Engineering Quiet
An interactive 3D noise map showing how a roadside sound barrier, vegetation buffer, and active noise-cancellation array combine to lower decibel levels behind a city street.
A live 3D noise map of a city street cross-section, showing how a sound barrier, a vegetation buffer, and an active noise-cancellation speaker array combine to pull decibel levels down at a building behind the road.
🔬 What It Demonstrates
Traffic noise decays with distance, is diffracted around barrier edges, softened by vegetation, and further reduced in a local zone by phase-inverted sound from an active cancellation array — each layer visible as colour shifts on the ground-plane noise map.
🎮 How to Use
Adjust traffic noise level, barrier height, and receptor distance, then toggle the vegetation buffer and active noise cancellation array to see the read-out at the receptor marker change in real time.
💡 Did You Know?
The WHO recommends keeping average road-traffic exposure below 53dB Lden; a well-designed barrier plus active cancellation can realistically claw back 15–20dB in the "quiet zone" closest to the array.
