18个人被确定了需要闻一种气味才能辨认出来的时间。使用热线风速计和示波器监测嗅觉持续时间、容量和吸入率。在实验1中，受试者使用1、3或5种天然气味，或无限数量的天然气味来采样七种不同的单一气味，这些气味的感知强度不同，并证明每种气味都可以用一种气味来识别。在实验2中，受试者展示了他们可以用最短的嗅觉(0.42秒)来识别每种气味。在实验3中，对两种不同浓度的气味进行的测试表明，嗅觉持续时间在略高于识别阈值的狭窄浓度范围内影响识别。这些结果与描述气味检测和气味强度感知的最佳条件的早期数据一起，提供了开发标准嗅觉仪和人类嗅觉测量标准方法所必需的信息。
The duration that a single odor needs to be sniffed for identification was determined for 18 humans. A hot wire anemometer and an oscilloscope were used to monitor the duration, volume and inhalation rate of sniffs. In Experiment 1 subjects used 1, 3 or 5 natural sniffs, or an unlimited number of natural sniffs to sample seven dissimilar single odors of mnoderate perceived intensity, and demonstrated that each odor could be identified with a single sniff. In Experiment 2 subjects demonstrated that each of the odors could be identified with the shortest sniff (0.42 sec) they could physically achieve. In Experiment 3 tests with two of the odorants at several concentrations showed that sniff duration influences identification over a narrow range of concentrations that is just above the recognition threshold. These results together with earlier data that described the optimum conditions for the detection of an odor and the perception of odor intensity, provide information that is necessary for the development of a standard olfactometer and standard methods for human olfactory measurements.
