NRS + DISPLAY VARIO NIS

The mobile version of the NRS (Noise Reduction System) is a combination of a sound level meter and the VARIO NIS Display. It is used to reduce harmful noise emissions especially in residential areas. The NRS records the volume of passing vehicles and transmits a radio signal to the distant LED display (max. 100 m) when an adjustable threshold value (dBA) is exceeded. The display provides direct feedback to the driver that can be individually set as "Too much noise!" Emoticons and other customized symbols can be displayed on the display.
