Sound Levels and Food Eaten (04-11-19)

Graziose and colleagues investigated how sound levels influence food consumed and their findings have implications, generally, for situations when designers want to encourage certain behaviors, particularly by children.  The researchers report that “A digital photography method was used to assess FV [fruit and vegetable] consumption among [second and third grade] students across 40 days from 20 schools and environmental exposures, including the noise or sound pressure level of the cafeteria, were assessed during lunch. . . . . Combined FV [fruit and vegetable] consumption was negatively associated with noise exposure. . . Among young children eating in cafeterias, increased noise levels may decrease consumption of fruits and vegetables at the school lunch meal. We hypothesize that increased noise can work in two ways to decrease FV consumption: increased socializing (i.e., talking) and/or decreased hedonic [pleasure-related] enjoyment of the school lunch meal.”
