LA-2295 (RP-108) -- Perception of Odor Intensity and the Time-Course of Olfactory Adaptation

This report is concerned with the perception of odor intensity by human beings. It focuses in particular on (a) how perceived magnitude changes during prolonged exposure to an odorant; (b) how perceived magnitude varies with concentration for various odorants; and (c) how the presence of low concentrations of a masking agent alters the perceived magnitude of a test odorant.

The report comprises two parts. Part I deals with perception of intensity and adaptation for I-propanol and eugenol. Part II deals primarily with perception of intensity, adaptation, and masking for ozone and n-butyl acetate.
