在应用风味研究中使用的“气味单位数”有几个不同的名称，既不是气味剂的绝对物理浓度的单位，也不是感知气味强度的心理物理测量。这一概念的使用已被证明是基于隐含的假设，这些假设在某些方面与目前的心理物理知识相矛盾。一个特殊的后果的混合物阈值的气味单位数量的组件和混合物的数量，从他们的部分之间的关系的定义进行了简短的讨论。最后，几句话是专门在气味混合物的相互作用现象的研究心理物理学的方法。
The “odour unit number” used in applied flavour research and known by several different names, is neither a unit of absolute physical concentration of an odorant, nor is it a psychophysical measure for perceived odour intensity. The use of this concept has been shown to rest upon implicit assumptions which are contradictory in some respects to present psychophysical knowledge. A special consequence for the mixture threshold value of the defined relationship between odour unit numbers of components and that number of the mixture from which they are parts was shortly discussed. Finally, a few words were devoted to a psychophysical approach in the study of interaction phenomena in odorant mixtures.
