Sensory science quantifies perceptual attributes through structured descriptive analysis

Evidence

Researchers have attempted to identify relationships between particular features in the outputs from acoustic musical instruments and their perceived timbre. A significant experiment in this field was conducted by Grey (1977). Listeners were asked to rate the similarity between recordings of pairs of synthesized musical instruments on a numerical scale from 1 to 30. All sounds were equalized in pitch, loudness and duration. The results were analyzed by “multidimensional scaling,” which is a computational technique that places the instruments in relation to each other in a multidimensional space based on the similarity ratings given by listeners. — David M.
