Abstract The purpose of this study is to investigate the effects of floor impact noise on indoor environmental comfort. Subjective assessments were conducted with 32 university students in an indoor environmental chamber. A 4 (floor impact noise types) × 4 (background noise types) × 2 (background noise levels) × 3 (room air temperatures) × 2 (gender) within-subjects factorial design was employed, and factorial ANOVA was applied to analyze the data. The effect size of floor impact noise on indoor environmental comfort was investigated using partial eta squared from the ANOVA results. The correlation coefficients between indoor environmental comfort and each subjective attributes were calculated. The indoor environmental comfort was highly correlated with the thermal comfort as well as floor impact noise annoyance. The effect size of floor impact noise was greater than that of room temperature on indoor environmental comfort. When floor impact noise occurred, the acoustic environment was more important than the thermal environment with temperatures of 20 to 30°C.
