Abstract
Two olfactometers can simultaneously but independently provide stimulation to the eyes and nose of a human subject. Thus, a sample of air containing an odorant is delivered to the eyes only, nose only, or both eyes and nose of the subject. Physiological responses such as eye blink rate and breathing rate are observed and automatically recorded. Psychophysical responses such as ratings of ocular or nasal irritation also are recorded. The apparatus is useful in collecting data regarding fragrances and environmental air quality.
