  author={Fabien L{\'e}tourneaux and Fabrice Aubin},
The reduction of the rolling noise produced by freight wagons is one of the major challenges of the railway sector to develop the freight traffic. In that context, the development of new types of brake blocks (made of composite material) which tend to smooth the wheel tread and then to drastically reduce the rolling noise excitation have been developed. This paper presents an acoustic acceptance procedure which is to be included within the general approval procedure of these composite brake… Expand
