Biosystems, 1993
A model for coding of odor intensity in the first two neuronal layers of olfactory systems is proposed. First, the occupation and activation by odorant molecules of receptor proteins of different types borne by the first order neurons are described as birth and death processes.

Optimum perception of odor intensity by humans
Physiology and Behavior, 1985The sniff duration that provides optimum perception of odor intensity was determined for 17 humans. Subjects were trained to match the duration of their sniff to the duration of a buzzer that sounded for 0.2, 0.5, 1.0 or 2.0 sec. Sniff characteristics were monitored with a hot wire anemometer and an oscilloscope.

Measurement of Odor Intensity by an Electronic Nose
Journal of the Air & Waste Management Association, 2000The possibility of using electronic noses (ENs) to measure odor intensity was investigated in this study. Two commercially available ENs, an Aromascan A32S with conducting polymer sensors and an Alpha M.O.S. Fox 3000 with metal oxide sensors, as well as an experimental EN made of Taguchi-type tin oxide sensors, were used in the experiments.

The “Penetration and Puncturing” theory of odor: Types and intensities of odors
Journal of Colloid and Interface Science, 1969Abstract In this paper the quality of odor is explained on the basis of a postulated range of nerve endings in the nose, characterized by somewhat different lipid compositions of the membranes. Some odorants can penetrate certain types of cell wall, while not having sufficient energy to penetrate others.

Effect of odor quality and intensity on conditioned odor aversion learning in the rat
Physiology and Behavior, 1982Odor quality and intensity were varied to test the ability of rats to associate odor with an induced illness. Rats were allowed 10 minutes access to water on each of nine days; deodorized air was directed towards each rat's nose while drinking at familiarization and recovery sessions (days 1-5 and 7-8, respectively) and odorized air at treatment and ...

Total Intensity of Odor: A New Method to Evaluate Odors
Journal AWWA, 2017Unpleasant odors in drinking water can have a negative effect on consumer confidence. In fact, consumers often perceive that if their water smells bad, then it must be bad and unsafe to drink. Compliance for odor aesthetics of drinking water in the United States is based on a secondary standard using the threshold odor number (TON) method, a dilution ...

Effects of Fluctuating Odor on Odor Intensity and Annoyance
1994The influence of fluctuation of an odor as a pollutant on the perception is not clear, since there has been little research on the effect of fluctuating odors on humans. Hence, the present study was undertaken to clarify the effect of the time-pattern of fluctuating odors on overall perceived intensity and feelings of annoyance.

Quantitative Prediction of Odor Intensity
Transactions of the ASAE, 1976ABSTRACT THE relationship of odor intensity of odorant mixtures and individual odorant concentration has been investigated using hydrogen sulfide, methylamine and ammonia. These are common odorants in animal production facilities. Mathe-matical equations based on these data have been developed to predict odor intensity.

Odor Intensities at Cattle Feedlots
Transactions of the ASAE, 1977ABSTRACT ODOR intensities measured at two cattle feedlots in Texas ranged from 1.5 to 170 dilutions to threshold (DT), which covers the measurement range of the Barnabey-Cheney Scentometer. The average odor reading at the surface of a 4000 head feedlot, determined by monitoring four randomly selected pens for 7 mo, was 31 DT. The run-off settling basin
