Noise control system

Noise Control System
Enables selection of acceptable noise
levels within classrooms, using the traffic light system. As noise levels increase, lights change
from green to yellow then red with or without sound.
Noise becomes visible for all children.
An adjustable sound level meter controls the decibel level. Table mount or wall brackets included.
Due to the newly-made battery operation you are independent from cabling. The LED signal
lights with a durability of about 100.000 power-on hours are ready for use at any place and
any time. Thanks to rechargeable batteries (not included) a continuous operation of 6 hours is possible
