Abstract
ABSTRACT
In this paper an experimental activity regarding the detection of noise produced by a
high velocity train along a “almost” straight railway, and a semi-quantitative theoretical
model which gives the shape of trains noise in that running conditions, are described.
During this investigation the comparison between software predictions and
experimental measurements was focused. At the present stage of our study we are
starting with the theoretical reproduction of the time history of the phenomenon. In a
previous paper we reported about the same goal referred to low velocity trains with very
different operating conditions. So in this work we try to underline differences and
similarities.
The experimental measurements procedure is based on the detection of the sound
level outside a building placed in an interesting position with respect to the rail line. It is
some three hundred meters far and in a position from which one can observe more
than three kilometres of railway. Measurements were performed by a first class
Measuring System.
