Abstract

The number of microphones and the configuration of the microphone array together determine the properties and ability to localize and quantify, as well as determine the source strengths of high-speed train noise sources, which is the goal of this work. The microphone array should perform well in most frequency regions of interest, inclusive of their low-frequency behavior. In order to improve the performance levels of these arrays, microphone configurations are studied to optimize the performance for the identification of the acoustical characteristics of train noise sources and to realize the best configuration to increase in-situ measurement knowledge.
