Factors that affect the olfactory signal. The olfactory signal strength one receives is dependent on several factors as illustrated in the figure. Temperature, humidity, atmospheric pressure and airflow all relate to one another and collectively exert an effect on the evaporation rate of the nasal mucus layer as well as the odorants themselves. This forms the basis on which the other variables act to provide the observed olfactory signal strength
