Sensory scales can be calibrated for equal intensity across different attributes

Evidence

In spectrum descriptive analysis, the panel consists of 10 to 15 screened subjects who develop technical expertise through a comprehensive training procedure. A descriptive terminology is built covering all the perceptual attributes using a set of absolute category scales calibrated to have equal intensity across the attributes. For example, grade 5 on a sweetness scale is defined to have equal intensity with grade 5 on a saltiness scale. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 938
