TY - JOUR N2 - Assessments of odour nuisance are made using one of the psychophysical laws: logarithmic Weber- Fechner law or power law by Stevens. The object of the work was to determine whether one of the laws exhibits advantage over the other. To evaluate the two laws series of odorimetric measurements of aqueous solutions of acetic acid were made. Values of Pearson' correlation coefficient were calculated for relationship of the odour intensity (I) versus logarithm of the acetic acid concentration in air (Iog., C [mg/rrr'I) as well as for the relationship of logarithm of the odour intensity (log,0/) versus logarithm of the acetic acid concentration in air (log., C [rng/nr'[). Both laws are fulfilled equally well in a range of investigated concentrations of acetic acid.
