本研究致力于研究耦合力对骨传导阈值测定的影响。本研究的特点如下：(1)通过一些机械装置，使用了250-750克(以100克为间隔)的系统耦合力；(2)采用Bruel和Kjaer 8000型机械阻抗头(带有微型振动器)进行测试；(3)分析了不同耦合力下骨传导阈值的重测变化；(4)研究了耦合力影响下听力水平的变化。
The present research is devoted to the study of the effect of coupling force on bone conduction threshold determination. The following characteristics of this investigation are listed: (1) A systematic range of coupling forces from 250 to 750 grams (in 100-gram intervals) is used by means of some adopted mechanical devices; (2) A Bruel and Kjaer mechanical impedance head type 8000 (with a mini-shaker) is employed for testing; (3) Test-retest variabilities of bone conduction thresholds are analysed under different coupling forces; (4) Variation of hearing levels under the effect of coupling force is studied.
