IMPROVING THE SOUND AND HEAT INSULATION OF RAIL VEHICLES WALLS

The function of a rail vehicle wall is essentially determined by the mean sound insulation value R and the coefficient of heat transition k sub 1. Measures taken for improving the sound absorption coefficient differently operate on the heat insulation. While the application of an antinoise compound does not influence k sub 1, R increases by 4 to 5 dB, different insulating materials used in the intermediate space changing k sub 1 considerably, but R to a small degree only. The inside wall material has an opposite influence, so that either a good sound insulation or a good heat insulation remains to be chosen. By these rules the wall design will be facilitated.
