Will high speed trains change Portuguese railway noise?

摘要

This paper presents the in situ evaluation of noise from railway traffic on a modernizedsection of the Portuguese railway network. The measurements include noise spectra forfour types of Portuguese rolling stock in terms of their maximum Transit Exposure Level(TEL), equivalent Sound Pressure Level and frequency content. The obtained data allowsfor a noise characterization of the various types of Portuguese trains and can be used in thevalidation of numerical noise prediction models. Due to the foreseen introduction of highspeed railways in Portugal an analysis is done to check how the railway noise will change inthe near future with these new trains.
