Mozart's or Ambient Music do not Affect Autoalgometric Pain Threshold.

Abstract

Nowadays, researchers and clinicians are increasingly interested in alternative non-pharmacological treatments, and music therapy seems to have additional and powerful effects on different pathologies and pain. However, since pain is a subjective perception, it is difficult to evaluate if and which effect music has on it. In this study, a new device and method have been introduced to objectively estimate pain threshold and its changes related to external stimuli. The above-mentioned device, called autoalgometer, allows to evaluate pain threshold changes while listening to music or other sounds. In this experiment, the pain threshold was evaluated in twenty-seven volunteers after listening to one out of three different soundtracks: white noise, Mozart's sonata K448 or Brian Eno's ambient music. Compared to staying in silence, listening to the recordings had no significant effect on pain threshold, and the results did not show any significant difference between the experimental groups. Probably, the positive effect of music described in other studies can be ascribed to a psychological effect, meaning that music can improve subjective mood and, thus, modify pain perception.
