Abstract: Conventionally powered cars produce noise from the combustion engine and exhaust system. Electric cars do not have an internal combustion engine, and therefore no intake, exhaust or gearbox, so noise is generated mainly as a result of variable electromagnetic forces accompanying the conversion of electrical energy into mechanical energy. All vehicles equipped with both conventional and diesel engines also emit noise as a result of the interaction of the tyres with the road surface and from the air flowing over the body (aerodynamic noise). The article measures noise inside and outside an electric vehicle. The measurements were carried out in city and highway traffic conditions. Research has shown that the main source of noise is the interaction of tyres with the road surface and aerodynamic noise.
