The purpose of this study was to investigate short-term masticatory muscle reactions in response to simulated noise and music sound. Hypothesis of this study was that loud noise would cause increased stiffness and decreased elasticity of the masticatory muscles compared to low level of noise or identical sound level of music.
Fifteen male volunteers were recruited for the study. The sound levels of noise and music used here were 60 §¼ and 100 §¼. The experiment comprised 4 sessions, Session 1 with 100 §¼ of noise for the 1st day of experiment: Session 2 with 100 §¼ of music for the 2nd day: Session 3 with 60 §¼ of noise for the 3rd day: Session 4 with 60 §¼ of music for the 4th day. Stiffness and elasticity on the anterior temporalis and superficial masseter muscles were measured with tactile sensor before and 2, 4 and 6 minutes after exposure of sound.
The study indicated that, in short-term exposure of sound, there was no significant difference between noise and music at both 60 and 100 §¼ of sound level, but that there were partially significant differences between 60 and 100 §¼ of sound level regardless of sound type. This suggest that high level of sounds like 100 §¼ used in this study, in spite of short term exposure of several minutes, would lead to masticatory muscle contraction, especially in the masseter muscles.
