This study evaluated the effects of rise‐decay time and intensity (70dB; 90dB| of pure tones on cephalic and finger vascular responses. Cephalic dilation responses similar to those reported by Sokolov were obtained, as well as cephalic dilation response*, which were interpreted as attributable to startle. Cephalic constriction responses were observed at 90dB only and occurred more frequently for slow rise than for fast rise tunes which were conducive to the production of startle. The negative results with respect to (he cephalic vasomotor response, reported by most American investigators, can be rationalized from the results of the present study.
