Key result
Loud auditory stimuli alter gastric peristalsis in over ~50% of subjects, independent of subjective fear.
Why the study?
The study aimed to investigate stomach reactions to an unexpected loud auditory stimulus and their relation to stomach features under normal conditions.

Does a loud auditory stimulus affect stomach peristalsis in human subjects?
An unexpected loud noise causes temporary suppression of stomach peristalsis in over half of subjects, without correlation to subjective fear or other bodily reactions.
Jungmann et al. (1952) reported an observational. Loud auditory stimulus (unexpected gunshot noise) vs. Baseline (normal conditions before stimulus) was evaluated on Changes in peristaltic rate and amplitude. A loud auditory stimulus altered stomach peristaltic rate and amplitude in over 50% of subjects, with no correlation found between stomach reactions and reported fear or other bodily reactions.
