摘要:
目的:应用骨导麦克风收集正常成人咀嚼运动产生的咀嚼音,并对咀嚼音特点进行初步探索。方法：随机选取均角骨面型的个别正常牙合在校大学生30名，其中男性13名（平均年龄26.8岁±2.1岁），女性17名（平均年龄26.3岁±1.8岁）。每人咀嚼4粒熟花生米，每粒花生米重量为（2.24±0.16）g。使用骨导麦克风记录咀嚼音， praat5.4.04 软件收录录音样本wav文件，分析男女两组音强(MI)、最大音高（MP）差异及 MP、MI与咀嚼循环次数(MC)和咀嚼时间(MT)之间的相关性。结果：男女两组咀嚼 MI、MP， MC和 MT差异都不具有统计学意义。咀嚼MC与 MT相关系数为0.804(P＜0.01)，咀嚼音 MI和咀嚼 MC、MT相关系数分别0.992(P＜0.01)、0.844(P＜0.01)，均呈高度正相关。而 MP与咀嚼MC、MT无相关性。结论：咀嚼音强可做为咀嚼运动中耗能的参考指标；正常成人男女咀嚼音强、最大咀嚼音高无统计学差异。
Abstract:

Objective ：To study the characteristics of the sound of normal human masticating recorded by the bone-conducted microphone Methods: A total of 30 subjects were chosen randomly in the college， 13 male and 17 female. The average age of male was (26.8±2.1)years old, and female (26.3±1.8)years old. Four similar volume peanuts masticated by every subject were weighted (2.24±0.16)g. The sound of the subject masticting by the bone-conducted microphone of BONE VIBRATION HEADGEAR was recorded. The masticatory time(MT) and the number of masticatory cycles(MC) were branded by the praat 5.4.04 and the intensity of masticatory sound(MI) and the pitch of masticatory sound(MP) were calculated. The statistic difference and correlation between the male and female and the correlation among MI,MP，MC and MT were analysed. Results: The differences in male and female were not statistical significant (P< 0.05).The correlation coefficient between t MI and MT was 0.992(P＜0.01)，between MI and MC 0.844(P＜0.01)，between MT and MC 0.804(P＜0.01).The correlations among MT,MC and MI were significant positive. And there was no correlation between MP and MC,MT .Conclusion: The energy consumption of normal humam masticatory could be reflected by the intensity of masticatory sound. There is no statistic difference between MP and MI in male and female.
