Noise Reduction at Urban Hot-Spots by Vehicle Noise Control
In the present paper the potential for reducing noise exposure at “urban hot-spots” due to rail traffic is investigated. In particular vehicle based control measures are discussed including various measures against curve and brake squeal, intelligent fan speed regulation taking advantage of the thermal inertia of the systems to be cooled, choice of fan types and innovative energy storage devices. It is shown that dedicated measures on the vehicles can lead to significantly reduced emissions at locations where people are mostly disturbed.
For future decision making on urban noise control measures it is essential that the calculation models used must incorporate in sufficient detail the source mechanisms that are mostly relevant from a disturbance perspective.
