OLFACTORY CHARACTERISATION OF CAR CABIN USING THE LIBRA NOSE

摘要

The customer increased sensitivity to air quality problem and the natural influence of smell on human behaviour affect the purchasing decision as the opinion on the vehicle quality during its life. So the olfactory quality is an even more important issue. Since the early 80's the car manufacturers have been working on the olfactory quality assessment using panel tests with trained or untrained sniffers. The subjective tests are expensive and require a not negligible time to be organised. The Centro Ricerche FIAT evaluated the applicability of an electronic nose to assess the odour quality and compared the obtained results with the votes of a jury.
