According to chicago cubs earrings the condition that brake resistor of locomotive no considering noise reduction requirements, background and status of noise research and control on the locomotive braking resistor devices were introduced.By analyzing the near-field surface sound power and spectrum of the resistor device, the main noise and frequency composition could be identified, and further the noise trailmaster challenger 200x reduction approaches were proposed for the braking resistor devices.
