Measurement noise level of E-bus HIGER KLQ6125GEV3 on the polygon

Abstract

Abstract Buses for public city transport in cities represent a significant source of noise, especially in the central city zones, on the traffic corridors with the highest hourly frequencies of public transport vehicles. The introduction of electric buses is one of the possible ways to reduce noise. The paper will present the results of the experimental measurement of noise levels of e-bus Higer KLQ6125GEV3 on the polygon, using the Lutron SL-4001 measuring instrument, following UN ECE 51.02 regulations and a comparison with the results of noise levels measurement with buses on diesel and CNG driveline.
