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: A systematic range of coupling forces from 250 to 750 grams (in 100-gram intervals) is used by means of some adopted mechanical devices; A Brüel & Kjaer mechanical impedance head type 8000 (with a mini-shaker) is employed for testing; Test-retest variabilities of bone conduction thresholds are analysed under different coupling forces; Variation of hearing levels under the effect of coupling force is studied.
