Streszczenie: Abstract. In this paper, some results of heavy vehicle traffic measurements were used to
simulate noise measurands by the Cnossos-EU method for this purpose. Heavy vehicle traffic
volume and velocity were recorded by a permanent automatic monitoring station. The noise was
calculated in octave bands. The results were described using parameters such as the median,
average peak noise, average maximum noise, first and third quartiles and relative measures of
noise. The values of these parameters were expressed in mPa or dB(A). It was shown that
maximum values of the acoustic pressure (mPa) occur for the frequency of f0=500 Hz but of the
acoustic pressure level (dB(A)) for f0=1000 Hz. The dispersion of noise and type A uncertainty
of the results were evaluated. Depending on the adopted noise unit, different shapes and
distribution parameters were obtained.
