This free, browser-based tool predicts how sound from an outdoor event stage travels across the surrounding area. Place one or more stages on a satellite-referenced site plan, set each stage's level at a calibration point, and the calculator estimates the sound pressure level at receiver points and across a grid noise map, in dB(A) and dB(C).
Festival and event producers, sound engineers and site planners who need an early estimate of off-site noise before a show: where to orient a stage, which neighbouring properties are most exposed, and what level is realistic at the mix position. Results are predictions for planning, not a substitute for on-site monitoring or a formal acoustic assessment. The workspace is built for desktop screens.
The calculator is made by Cadence Ops, the operations platform for live event production: crew, gear, logistics, compliance and finance in one place. Read the festival site map planning guide, see event production software, compare pricing or book a demo.
