- W591296030 abstract "An innovative method for the identification and comparison of mobile acoustic sources was implemented: the microphone array. Basis of the method is the beamforming algorithm that from a measure of the acoustic pressure in several points enables the investigation of the position and the characteristics of the sound source. This source can be either fixed or moving with respect to the array making the method capable of separating different sources among a general noise signal perceived during a vehicle pass-by. The method was developed using numerical models and proved to be effective testing it on site with different known sound sources both fixed and moving. After these tests an application of the pass-by noise measurements generated by a rail convoy was investigated. The occasion was given by an experimental campaign settled for the evaluation of noise and vibration emission of a standard ballast superstructure, within a European research program HIPERTRACK. Results showed that the method is able to distinguish multiple sound sources and in particular the possibility to identify the noise emitted by a single wheelset. An analysis of the noise emitted by the wheel-track interaction of different convoy typologies, on the same ballast superstructure, was performed and results are discussed. Comparisons between noise and vibration recorded on the rail showed a good agreement. Time/frequency analysis was finally implemented to identify the emission spectrum associated with every single bogie. For the covering abstract see ITRD E123761." @default.
