REDUCING THE NOISE FROM MOVING TRAINS, AND RHEOSTAT TESTS ON LOCOMOTIVES

Measurements have shown that train noise is a function of speed, the type and engineering characteristics of the rolling stock, and upper-level track structure. A table is presented that displays decibel readings for passenger and freight trains at 40 and 60 mph and for seven types of loaded and unloaded locomotives. According to Soviet town planning regulations, residential structures must not be located closer to a railroad track than 100 meters in cities nor 50 meters in other settlements, while rheostat tests of locomotives must be made not less than 300 meters from residential areas. Investigation has shown that these regulations are insufficient to satisfy the sanitary norms for noise levels in living quarters. It is suggested that in existing communities a measure be generally adopted that has proved effective at the L'Vov West railway Station, where rheostat measurements have to be made 90 meters from a residential area. In that case a 15-meter-high screen made of sintered brick and placed 18 meters from the locomotives produced a 20 dB reduction in sound pressure level and a fourfold reduction in subjective evaluation of noise. Similarly, a school outside Vyborg was adequately protected against noise from passing trains. A series of formulas is presented that prescribe the distance from the noise source at which screens should be placed to have the greatest effectiveness. Planning for future communities should take into account the noise-absorbing characteristics of vegetation at various distances from noise sources.
