✦ Synopsis

This paper presents models for predicting the equivalent level, Leq of railroad noise. For open terrain two cases are considered." with and without ground effects (second section). On the assumption that, at a given point, Leq = Le* is required, the problems of barrier length, height and position are discussed (third section). Examples of the application of presented theories are given.

## A BSTRA CT Expressions for A-weighted sound pressure level and A-weighted sound exposure of a passing train are derived. It is assumed that geometrical spreading is the major factor influencing the noise propagation. The effect of screening by an infinitely long barrier is analyzed.

of a variety of tasks. However, it would appear that this form of display demands more of the operator's attention than other forms of indication. Finally it is pointed out that a number of additional problems relating to numerical displays are in need of investigation. 1.3.53(54004) Smith, F., Lott
