title: [Stapedial reflex under auditory masking of bone canal: 1- The effect of white noise on threshold values].
abstract: The authors have studied the behaviour of the A.R. threshold under bone way masking sent to the vertex. The masking caused changings of the recorded track; a change of the compliance was observed in the 60% of the subjects and a rythmic waving of the (isoelectric) line was observed in 40% of the subjects. Upon these changes the A.R. were recorded for the tone test sent at similar values (almost equal) at those recorded without any kind of masker, even if a threshold shift sometimes big, existed because of the high intensity of the masking noise. The authors are making further researches to explain the meaning of these changes.
