HIGHLIGHTS
- who: Ziqin Lan et al. from the Beijing, China School of Automobile and Transportation Engineering, Guangdong Polytechnic Normal University have published the article: Noise Emission Models of Electric Vehicles Considering Speed, Acceleration, and Motion State, in the Journal: (JOURNAL)
- what: The models describe a linear relationship between the noise level the logarithm of speed and the for multiple states (i.e. the constant-speed the and the deceleration From the spectrum analysis the low-frequency noise is barely affected by the speed and but the noise at a certain frequency is most sensitive to them . . .
