The Psychophysical Structure of Complex Underwater Sounds.
Abstract
Eight complex passive sonar recordings were selected to represent a range of common natural and man-made underwater sounds. Nine musically experienced and ten musically inexperienced observers rated the similarity of all possible pairs of the eight signals using a five-point scale. These proximity data were decomposed using the INDSCAL multidimensional scaling program into an interpretable three-dimensional perceptual space. Two of these underlying dimensions reflected the overall shape of the 1/3- octave spectra of the eight signals, while the third was seen to reflect the prominence of a low frequency periodicity present in some signals. The perceptual spaces for musically experienced observers and musically inexperienced observers differed reliably in the relative importance or salience of the three dimensions.
