Natural Sniffing Gives Optimum Odour Perception for Humans

摘要: The characteristics of human sniffing episodes during odour perception have been described in an earlier paper, where it has suggested that the techniques used by individuals may be close to those providing optimum perception. To investigate this suggestion, threshold and intensity tests with butanol, cyclohexanone, pentyl acetate carried out on twenty-one subjects. Olfactory responses obtained using natural were compared number sniffs, interval between size sniffs varied. results indicate is very difficult improve efficiency a single sniff provides as much information about presence do seven or more sniffs. A first episode shown similar most significantly both unaffected changes concentration type od...
