Traffic Light System

Green, yellow, red.
It's that simple.

The operator looks at the dashboard and immediately understands the status. No training in acoustics is needed, nor is it necessary to interpret how many decibels are permitted by law.

SAFE ZONE
0 – 70 dB
Normal volume — no action required.
CAUTION ZONE
70 – 90 dB
Noise levels are increasing — the operator should take action.
DANGER ZONE
90 dB +
Limit exceeded — take immediate action.
