Introduction

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.

Methods

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.

Results

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.

Conclusion

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

Implications

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

MRI噪声会影响化学感觉知觉吗？

介绍

声音会影响食物和风味的感知。例如，很大的噪音会影响味觉。在本研究中，我们检查了暴露于〜80 dB的磁共振成像（MRI）声噪声是否会影响味觉。

方法

参与者（N  = 27）两次来到实验室进行味觉测试，气味测试以及评估甜咸食品：一次连续暴露于MRI大声噪声中，一次暴露于更安静的背景噪声中。据推测，暴露于大声噪声会损害味觉，特别是识别和检测甜味，并且会降低对特别甜味食品的喜好。

结果

暴露于MRI声波噪声不会影响整体味道检测或甜味检测。此外，我们发现噪声对甜食的喜爱没有影响，但探索性分析的确暗示了MRI噪声对咸味食物的喜爱的影响，当暴露于MRI声噪时，这些食物的受欢迎程度大大降低。

结论

我们得出的结论是，嘈杂的声音不一定会影响化学感觉的感知。

含义

MRI声学噪声似乎对气味和味道没有明显影响。
