Abstract
This study was carried out to investigate effects of room temperature and relative humidity conditions on the olfactory threshold, odor intensity and hedonics. The panels were consisted of seven young male subjects. Skatole, isovaleric acid, and β-phenylethyl alcohol were used as odorants. Olfactory threshold, odor intensity, and hedonic scale of odor were selected as measurement items. No significant difference was observed in the olfactory threshold, either among the odorants or among the room temperature and relative humidity conditions. Skatole showed the lowest mean olfactory threshold with a small standard deviation. The odorants showed a similar tendency in odor intensity and in the hedonic scale of odor. It was revealed that the panels' evaluations varied among the odorants more significantly under comfortable conditions (25℃, 50%) than under the other three conditions. Winter conditions (22℃, 20%) were revealed to have less effect on the panels' evaluations of various odorants. Isovaleric acid was revealed to be more sensitive to the effects of room temperature and relative humidity conditions than the other two odorants. β-phenylethyl alcohol and skatole were revealed to be less sensitive to the effects of room temperature and relative humidity conditions.
