Auditory feedback effect of mastication sounds on snack foods that have absorbed moisture

Abstract

To demonstrate the importance of sound in the perception of food texture, a sensory evaluation of texture was conducted using a custom device by feeding bone-conducted sounds generated during the mastication of potato chips through headphones as auditory feedback. In agreement with previous reports, it was verified that the perceived crispness was generally augmented depending on the presented sound pressure level. It is also suggested that enhanced mastication sounds have a complementary effect on deteriorated texture of foods that have absorbed moisture.
