STANDARDISATION OF DIESEL LOCOMOTIVES. NOISE ABATEMENT ON DIESEL LOCOMOTIVES SUPPLEMENT TO DOCUMENT NO. 8 (APPENDICES IV AND V)

In August 1960 the Control Committee approved a programme of tests drawn up by the Specialists Committee B 13 with a view to the carrying out of systematic noise level measures on Diesel locomotives, selected according to an agreed type scheme. The tests were carried out from the 5th to the 10th September 1960 on a line of the CFF at Croy-Romainmotier, between Vallorbe and Lausanne. The various noises produced by the Diesel locomotives could be compared under similar conditions on the same section of track, both by means of subjective measurements and by means of measurements. Furthermore, the tests enabled a comparison to be made between the measuring procedures employed by the various Administrations. An account of these noise level tests carried out at Croy-Romainmotier is given in the ORE report B 13/RP 8. The present report B 13/RP 9 contains additional statistical analyses on the measuring results obtained in the course of the noise level tests. For a better understanding of the report, the various test series have been reproduced in a clear way in the next chapter. The acoustical bases, together with the definitions of the various measuring units, as well as more precise data concerning the 10 Diesel locomotives examined, are described in detail in Report B 13/RP 8.
