Relationships of Chewing Sounds to Judgments of Crispness, Crunchiness and Hardness

Abstract

ABSTRACT The relationships between oral and auditory judgments of crispness, crunchiness and hardness were examined. Twenty subjects used magnitude estimation to judge the crispness, crunchiness and hardness of sixteen food items and sixteen tape recorded biting and chewing sounds. Correlations between oral and auditory judgments of each attribute were generally large. In addition, all three attributes appear to be very closely related.
