Road Noise Measurement System CAT PASS-BY NOISE
What is the Road Noise Measurement System
CAT PASS-BY NOISE?
CAT PASS-BY NOISE measures the noise (road noise) generated when automobiles and motorcycles are in motion, according to the international standard UN/ECE This is a driving noise measurement system for precise measurement and analysis based on standards such as R51.03 and R41.02.
It synchronizes and aggregates vehicle speed, position information, engine speed, and acoustic data from microphones installed along the course via wireless communication. It automates everything from monitoring weather conditions to complex calculations defined by standards, efficiently deriving the test results necessary for type approval applications.
