“…Thus, auditory spatial cues do not only contribute to auditory localisation, i.e. the ability to attribute a precise egocentric spatial co-ordinate to a sound, involving overt perception of sound location (Blauert, 1996) but play also a role in sound object segregation, sometimes referred to as 'auditory streaming' (Bregman, Fig. 3.…”

“…Under the present conditions, normal subjects hear two spatially disparate sounds, i.e. one sound image at the left ear and one sound image at the right ear (for further details see [3]). In this second test, 20 monaural sound stimuli, 10 to the left and 10 to the right ear, as well as 10 binaural incoherent sounds were presented following a quasi-random order.…”

“…For example, humans have repeatedly been measured to have MAAs near 1° for both low-and high-frequency pure tone stimuli (Mills, 1958;Perrott, 1969;Blauert, 1997), yet subjects who are required to actually indicate the spatial location of such stimuli often display large variability and poor accuracy in their responses (Stevens and Newman, 1936;Middlebrooks, 1992). There is also evidence of a discrepancy from animal studies.…”

Can measures of sound localization acuity be related to the precision of absolute location estimates?

Studies of sound localization use relative or absolute psychoacoustic paradigms. Relative tasks assess acuity by determining the smallest angle separating two sources that subjects can discriminate, the minimum audible angle (MAA), whereas absolute tasks measure subjects' abilities to indicate sound location. It is unclear whether or how measures from the two tasks are related, though the belief that the MAA is specifically related to the precision of absolute localization is common. The present study aimed to investigate the basis of this relationship by comparing the precision of absolute location estimates with a measure of spatial acuity computed from the same data. Three cats were trained to indicate apparent sound source locations that varied in azimuth and elevation via orienting gaze shifts (combined eye and head movements). The precision of these absolute responses, as measured by their standard deviation, was compared with acuity thresholds derived from receiver operating characteristic (ROC) analyses of the cumulative distributions. Surprisingly, the acuity measures were occasionally very poor indicators of absolute localization precision. Incongruent results were attributed to errors in mean accuracy, which are disregarded in analyses of traditional relative tasks. Discussion focuses on the potential for internal biases to affect measures of localization acuity.
