Descriptive sensory analysis maps perceived sound differences onto an N-dimensional attribute space

Evidence

Descriptive sensory analysis aims to identify, describe, and quantify the sensory attributes of stimuli using naive or trained human subjects (Piggott et al., 1998), and it is often described as the most sophisticated tool in sensory science (Lawless and Heymann, 1998). … The term elicitation is often used in this context, which means ‘the process of getting information from someone’. In this case, the elicited information is how the auditory events differ from each other, specifying all the attributes in which the differences are found, and also how much they differ in each of the dimensions specified by the attributes. This means that the researched sounds are projected to an N-dimensional space spanned by the elicited attribute dimensions. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 932
