摘要：

This work shows the results of a series of external noise measurements made on board a high-speed train. The tests were carried out using a specially designed device to be bolted to the axlebox of a carriage or locomotive protecting a microphone placed at a short distance in front of a single wheel. The philosophy of such a device is explained and the criteria regarding its design, the laboratory tests carried out on the device, its application to Italian State Railway's ETR500 train and the results obtained in various trials are reported. The reliability and repeatability of the results are analysed.
