Abstract
72 Ss were instructed to rate sounds under noisiness, annoyance, or both (composite). 4 factors of sound were investigated: (1) overall intensity, (2) fundamental tone frequency, (3) fundamental tone intensity, and (4) overtone intensity. Analysis of the interactions between instructional set and stimulus variables supported previous findings that instructions set Ss to give different emphasis to stimulus factors. The data further indicated that the emphasis given to different stimulus factors under the composite instructional set was a compromise between the emphasis given under noisiness and annoyance sets presented independently.
