Train Noise Monitor (TNM) is ideal for long-term environmental monitoring of railway noise, identification of noisy rolling stock, and assessment of railway noise mitigation treatments. TNM uses a high precision microphone to record noise levels and statistics during each train pass-by. FleetONE provides a user-friendly interface for noise data analysis, alerting, and reporting. TNM matches noise levels to individual rolling stock by using a camera or automatic vehicle identification (AVI) system consisting of RFID tag readers and wheel sensors.
