Abstract/OtherAbstract:
The study of the perception of loudness lends itself well to the psychophysical scaling technique of magnitude estimation. This study was designed to extend the range of auditory stimuli used to study the magnitude estimation scaling of loudness. The five stimuli chosen were a 1000-Hz pure tone, narrow band noise (700-1300 Hz band width), broad band noise (100-10,000 Hz band width), rock music, and babble speech, i.e., speech in which meaning is not discernible because several individuals are talking at once. Subjects were 30 normal young women (M = 19 yr.). During the auditory magnitude-estimation task for each of the five stimuli, a subject was instructed to assign numbers to stimulus presented in a randomly ordered series of nine sensation levels (10, 20, 30, 40, 50, 60, 70, 80, and 90 dB SL). Multivariate analysis of variance for repeated measures indicated there were no significant differences in the numerical responses of the subjects for the five stimuli. A possible explanation for these results is the presence of an underlying stabilizing factor (internal scaling mechanism) that allows adults to scale loudness consistently irrespective of the type of auditory stimulus.
