Hearing thresholds and acceptable limits of low frequency noise were measured for 21 ordinary adults and 10 complainants in psychophysical experiments, and the reliability and the validity of an evaluation method using the percentiles of acceptable limits were examined. In the results, the reliability of the acceptable limits for a bedroom in ordinary adults was high, and those values also agreed with equal unpleasantness contours from previous data. And the 10 percentiles of the acceptable limits for a bedroom most successfully discriminated the 1/3 octave band levels observed in the complainants' houses. Moreover, they were consistent with some of guidelines in European countries. The obtained results were utilized as "Reference values for mental and physical discomfort complaints" in "Handbook to Deal with Low Frequency Noise (2004)" which was published by the Ministry of Environment.
