Description
Summary:Although many people comment on their ability or inability to smell an odour, the accurate measurement of olfaction remains an elusive goal. Currently, there are no instruments available to objectively measure olfaction. This article outlines the design and early test results of a low cost, computer-based olfactometer which uses the frequency content of evoked potentials to quantify a subject's response to an olfactory stimulus. Clinical trials have been undertaken to establish the validity of the olfactometer and over a thousand tests have been carried out. Early results suggest that the methodology employed is appropriate and could be developed to enable a commercial olfactometer to be produced.
