PROBLEMS ENCOUNTERED IN SOUND MEASUREMENTS IN THE SNCB

The report is in two parts: the first concerns the sound measurements themselves and the second concerns the results of continuous automatic audiometric examinations. In general three locations of sound sources hold particular interest to the medical services of the railroads. They are 1) operator's cabs of diesel locomotives, 2) working areas for repair and mechanical drawing or their equivalent. We describe two types of apparatus for obtaining our results: a sound meter of the General Radio Company, type 1555A giving only total measurement in dB with the standard filter networks for A-, B-, and C- Scales, as well as an apparatus known as Kemplex which analyses the frequency dependence by octave band.
