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 a

✦ Synopsis
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.

In this work a simpli"ed device for the measurement of the noise emitted laterally by an UIC 60 rail is presented. It consists of three convergent parallel ducts with an anechoic termination to collect the sound energy in a straight, cross-square section pipe where measuring microphones are located.
This paper presents some of the results of field investigations on effects of exposure to noise and vibration from railway traffic. Effects on annoyance, sleep disturbances and psycho-social well-being as well as disturbance of different activities were evaluated by a postal questionnaire. Fifteen d
