Absolute auditory sensitivity and physiological strength of supraliminal stimuli

Individual difference in absolute auditory sensitivity has been studied in relation to the "strength - weakness" parameter of the nervous system as measured by V.D. Nebylitsyn's motor procedure, it is shown that both "weak" and "strong" subjects may possess high as well as low absolute auditory sensitivity, although there is tendency for higher absolute sensitivity in the weak group. A model is suggested which represents the growth of the nervous excitement in the range of stimuli from the individual absolute threshold up to 100 db in persons with weak and strong nervous system.
