| Research Abstract |
We investigated how the sound of chewing affects the perceived texture and pleasantness of food. Masticatory sounds were recorded prior to the experiment for each participant while chewing real foods. These artificial masticatory sounds were then presented to participants while they chewed several foods. The onset of the artificial sound was carefully timed with the onset of mastication. The results show that added masticatory sound affects the perceived texture of food and that added masticatory sound changes the pleasantness of foods, suggesting that we can control the perceived texture and pleasantness of food by adding artificially-created masticatory sound.
