Abstract Discomfort ratings of metal factory workers were compared with technical measurements and assessments of an external group. There was a good correspondence at the group level among the 3 ratings. About 90% of the workers' noise ratings agreed, but the lighting evaluation agreement was less. The highest correlation was that of equivalent noise level; this level and the lighting level which caused discomfort in about 50% of the raters were 50dB(A) and 900lux, respectively. Technical measurements are not sufficient to evaluate discomfort, but group level ratings of workers can be used instead of the technical measurements. Demographic and socio-economic variables, general job satisfaction, time of exposure or hearing ability had no significant effects on the results of discomfort ratings.
