Abstract

Sounds can affect food and flavor perception. For example, loud noise can affect taste perception. In the present study, we examined whether exposure to ~?80-dB magnetic resonance imaging (MRI) acoustic noise affects taste perception.

Participants (N?=?27) came to the lab twice for a taste test, a smell test, and evaluating sweet and savory food items: once when continuously being exposed to loud MRI acoustic noise and once when being exposed to much quieter background noise. It was hypothesized that exposure to loud noise would impair taste perception, especially identifying and detecting?sweet taste, and that it would decrease liking for the taste of particularly sweet foods.

Neither overall taste detection nor sweet taste detection was affected by exposure to MRI acoustic noise. Further, we found no effect of noise on sweet food liking, but exploratory analyses do imply such an effect of MRI noise on liking for savory foods, with these foods being significantly less liked when exposed to MRI acoustic noise.

We conclude that loud noises do not necessarily affect chemosensory perception.

MRI acoustic noise specifically does not seem to have a relevant effect on smell and taste.

MRI噪声是否影响化学感觉知觉?

声音可以影响食物和味道的感知。例如，巨大的噪音会影响味觉。在本研究中，我们研究了暴露于~?80分贝的磁共振成像(MRI)噪声影响味觉。参与者(N = 27)来到实验室进行了两次味觉测试、嗅觉测试，并对甜味和咸味食物进行了评估:一次是持续暴露在巨大的MRI噪音中，另一次是暴露在更安静的背景噪音中。据推测，暴露在嘈杂的噪音中会损害味觉，尤其是识别和检测?甜味，它会降低人们对甜味食物的喜爱程度。总的味觉检测和甜味检测都不受MRI噪声的影响。此外，我们没有发现噪音对甜食的影响，但探索性分析确实暗示了MRI噪音对咸味食物的影响，当暴露于MRI噪音时，这些食物明显不那么受欢迎。我们的结论是，噪音并不一定会影响化学感觉知觉。核磁共振成像的声学噪音似乎对嗅觉和味觉没有相关的影响。
