Musical expression is largely dependent upon accentuation, yet there have been few attempts to study the perception of dynamic accent in music or to relate the results of psychoacoustical research in intensity to realistic musical situations. The purpose of the experiment was to estimate the relationships among (a) the intensity increment in dB(A) required to meet an 80% correct criterion in the perception of one accented tone embedded within a seven-tone isochronous series of identical 87 dB(A) snare drum timbre stimuli of 333 ms onsets (accent level, or AL), (b) the different limen (DL) for intensity increase to meet a 75% correct criterion in a 2AFC task for pairs for the stimuli, and (c) the age of the subjects, all of whom have normal audiograms. / The 51 subjects (N = 51) were female nonmusicians ranging in age from 9 to 33 years (M = 17.98, SD = 5.21). The response tasks involved saying whether the second tone of each pair was louder or softer and circling the accented note in notated quarter notes. The stimuli production, the headphone calibration process, and their rationales were detailed. The global regression model was significant (F(2, 48) = 5.505, p =.007, $R\sp2$ =.187), and the relationship between AL and DL was not significant (F(1, 48) = 5.505, p =.197, $R\sp2$ change =.029), the relationship between AL and age was significant (F(1, 48) = 5.732, p =.021, $R\sp2$ change =.098) at an alpha level of.05 and power calculated at.66 for a medium ES. / It was concluded that accented sounds are easier to perceive in tone pairs than they are in a musical setting and that subject maturation improves performance of intensity judgement tasks. Suggestions for further research include shortening the length of the experimental session for younger subjects and increasing the number of intensity increments as well as using smaller increments to accommodate individual differences in perception. / Source: Dissertation Abstracts International, Volume: 53-03, Section: A, page: 0662. / Major Professor: Jack A.
