NOISE ABATEMENT ON DIESEL LOCOMOTIVES. NOISE MEASUREMENTS TAKEN AT LOCOMOTIVE FANS; NOISE-REDUCTION PROPOSALS BASED THEREON

This report covers noise measurements taken at the fans of: 10 diesel locomotives belonging to 5 different Administrations, 21 electric locomotives belonging to 7 different Administrations. It shows that in many cases the fans are responsible for most of the noise produced by the locomotive, and that it is worth taking steps to reduce the fan noise. This report represents the practical application of the theory described in report B 104/RP 4, published in April 1969, and in document DT 10, published in August 1968. On the basis of the acoustic power levels calculated from the characteristic data of various fans (driving power and air delivery rate), theoretical values and measured results were compared. This enabled statements to be made on the extent to which theory and practice agreed.
