Minimum audible angle thresholds for sources varying in both elevation and azimuth.
Minimum audible angle (MAA) thresholds were obtained for four subjects in a two-alternative, forced-choice, three up/one down, adaptive paradigm as a function of the orientation of the array of sources. With sources distributed on the horizontal plane, the mean MAA threshold was 0.97 degrees. With the sources distributed on the vertical plane (array rotated 90 degrees), the mean MAA threshold w...
متن کاملThe moving minimum audible angle is smaller during self motion than during source motion
WE ARE RARELY PERFECTLY STILL our heads rotate in three axes and move in three dimensions, constantly varying the spectral and binaural cues at the ear drums. In spite of this motion, static sound sources in the world are typically perceived as stable objects. This argues that the auditory system-in a manner not unlike the vestibulo-ocular reflex-works to compensate for self motion and stabiliz...
متن کاملDevelopmental changes in the precedence effect: estimates of minimum audible angle.
The precedence effect refers to an auditory phenomenon which occurs when two similar sounds are presented from different locations with a brief delay, and only one sound is heard whose perceived location is dominated by the first source. Although the lagging source si not localized as an independent event, under some conditions, adults are able to extract its directional cues. Developmental stu...
متن کاملBilateral cochlear implants in children: localization acuity measured with minimum audible angle.
OBJECTIVE To evaluate sound localization acuity in a group of children who received bilateral (BI) cochlear implants in sequential procedures and to determine the extent to which BI auditory experience affects sound localization acuity. In addition, to investigate the extent to which a hearing aid in the nonimplanted ear can also provide benefits on this task. DESIGN Two groups of children pa...
متن کاملSensory Behavior of Naval Personnel: M on Aural/binaural Minimum Audible Angle of Auditory Response
This paper considers what one ear contributes to man's perception of his auditory world and evaluates the monaural/binaural role in spatial orientation. Minimum audible angles were determined for monaural listening to moving sounds, and results were compared to similarly obtained binaural data. Much usable directionality existed for the monaural mode even at poor azimuths, and for both modes of...
