Sensory measurement: the rational assessment of private, sensory experience - its use, limitations and prospects.
This paper presents a broad spectrum of experimental results in psycho- physics, the science that relates sensory perception to physical measurements. For the first time, psychologists, food scientists and applications engineers can take subjective measures, and relate them to physical variations, by meaningful and actionable equations. Such equations permit predictions about expected sensory responses to product modifications. They can be used to guide the maximal sensory acceptance, or to help minimise the production costs of the product at an acceptable sensory level.
