Musical expression is often dependent upon accentuation, yet there is little research in the perception of dynamic accent in music and its relationship to intensity just noticeable differences (JNDs). This experiment estimated relationships among (a) accent limen (AL), (b) difference limen (DL), and (c) the ages of the nonmusician female subjects (N = 51). The AL was the intensity increment producing 80 % correct criteria in subjects' perceptions of single accented tones embedded xvithin seven-tone isochronous series. The unaccented tones were identical-timbre 87-dB(A) digitally produced snare drum sounds. The DL was the intensity difference in tone pairs that produced a 75% correct criterion. The relationship between AL and DL was not significant [F(1, 48) = 5.505, p = .197]. The relationship between AL and age was significant [F(1, 48) = 5.732, p = .021], suggesting that the amount of intensity change required for perception of intensity accentuation in musical set-I tings (especially by children) should be larger than the DL.

Difference Thresholds

Three kinds of intensity-difference thresholds were compared for the purpose of determining interaural-binaural and interaural-monaural relations. Five subjects were tested at 250, 2000, and 6000 Hz, using a variation of the Békésy technique. Response to 27 interaural intensity combinations were measured at each frequency. Monaural and binaural conditions were included. Each of 24 combinations was measured under 0° and 180° interaural phase conditions, and all were measured at 50, 35, and 20 dB HL (ISO). Results indicate that interaural-difference thresholds decrease as a function of level, as might be predicted. These thresholds vary as a function of the frequency and apparent azimuth of the fused tone, but are relatively insensitive to variations in interaural phase. Interaural intensity-difference thresholds differ significantly from both monaural and binaural difference thresholds.
