摘要
─—报导了在４４４位年龄范围很宽的受试对象的头部位置的力阻抗测量结果，取得频率由１００Ｈｚ到１００００Ｈｚ的数值曲线，揭示了共振频率对年龄的依赖关系，并导出其对应的统计的数学表达式。实验结果与国外有关文献作了对比。
The results of measurement for mechanical impedance on human head at the frequency range of 100￣1000 Hz for 444 subjects with ages from 5 to 65 y are described. A series of curves show tEat the resonance frequency will decrease with the increase of age and the relation equations between them aregiven. Finally, a comparison of our values with that obtained in other countries is shown.
