OLFACTORY ADAPTATION MODEL BASED ON DYNAMIC RESPONSE OF ODOR THRESHOLD

Abstract

The object of this study is to make an olfactory model applicable to olfactory sensation. Firstly, the experiment was conducted to obtain the data of psychological response of odor intensity under the odor concentration with step change on time series. Ethyl acetate was used as the target odor. Secondly, the theoretical olfactory model based on the impulse response function is constructed. By regression analysis on the varying odor intensity, two parameters of the exponential response function are identified. Lastly, unsteady state variations of odor intensity are calculated under various conditions of varying odor concentration.
