“…The displacement threshold, called the minimum audible movement angle, was shown to increase with the velocity of the source. The velocity threshold also increased with source velocity, and the results agreed with those obtained by Altman and Viskov (1977).…”

“…One method presents dichotic click trains, at first with no interaural differences. Successive clicks are presented with increasing interaural differences, and the sound appears to move from the center of the head to the ear receiving the earlier pulse (Altman, 1968;Altman & Viskov, 1977;Viskov, 1975). A second technique allows free field testing by initially simulating the position of a sound source located between two fixed speakers according to the law of sines (Bauer, 1961).…”

“…Viskov concluded that the dichotic click technique would be sufficient for the investigation of auditory motion perception. Altman and Viskov (1977) subsequently used the dichotic click technique to measure velocity discrimination. Velocity difference limens were found to increase from 10.8° to 19.3° as the velocity of the simulated moving image increased from 14° to 1400/sec.…”

This investigation examined the ability oflisteners to perceive apparent motion under binaural and monaural listening conditions. Fifty-millisecond broadband noise sources were presented through two speakers separated in space by either 10°,40°, or 160°, centered about the subject's midline. On each trial, the sources were temporally separated by 1 of 12 interstimulus onset intervals (ISO Is). Six listeners were asked to place their experience of these sounds into one of five categories (single sound, simultaneous sounds, continuous motion, broken motion, or successive sounds), and to indicate either the proper temporal sequence of presentation or the direction of motion, depending on whether or not motion was perceived. Each listener was tested at all spatial separations under binaural and monaural listening conditions. Motion was perceived in the binaural listening condition at all spatial separations tested for ISOls between 20 and 130 msec. In the monaural listening condition, motion was reliably heard by all subjects at 10° and 40° for the same range ofISOIs. At 160°, only 3 of the 6 subjects consistently reported motion. However, when motion was perceived in the monaural condition, the direction of motion could not be determined.

“…Some simulations replicate dynamic interaural intensity and time differences (e.g., Grantham, 1986). Others replicate only dynamic interaural time differences (e.g., Altman and Viskov, 1977). Generally speaking, MAMAs obtained with simulated movement are similar to those obtained with real movement (Grantham 1986;Perrott and Tucker, 1988).…”

The illusion of auditory apparent motion (AAM) was examined in order to determine the burst durations and interstimulus onset intervals (ISOIs) at which AAM is heard when spatial information regarding source location was varied. In the first experiment AAM was examined in the free field under monaural and binaural listening conditions. AAM was heard at the same burst duration-ISOI combinations for both listening conditions, but the location of the lead source could be determined only under binaural listening. In the second experiment AAM was measured with two and three sound sources. The number of sources did not affect the burst duration-ISOI combinations that produced AAM, but did affect the determination of the location of the lead source. In the third experiment AAM was tested when the sources were located in the median plane. The sources were located either at 0 ø and 150 ø azimuth, or both at 0 ø azimuth, one in the horizontal plane and one 20 ø above. The location of the speakers did not affect the timing requirements for the perception of AAM, only the timing requirements for the detection of the lead source. In the fourth experiment, AAM was measured when the vertical separation between the sources was either 2.5 ø or 20 ø. AAM was heard at both separations, even though 2.5 ø is less than the vertical IAAA. In each of these experiments only burst duration and ISOi determined whether motion was heard. Localization cues were important only for the determination of the direction of motion.

As a basic study into 3-D audio display systems, this paper reports the conditions of moving sound image velocity and time-step where a discrete moving sound image is perceived as continuous motion. In this study, the discrete moving sound image was presented through headphones and ran along the ear-axis. The experiments tested the continuity of a discrete moving sound image using various conditions of velocity (0.25, 0.5, 0.75, 1, 2, 3, and 4 m/s) and time-step (0, 0.02, 0.04, 0.06, 0.08, 0.10, 0.12, and 0.14 s). As a result, the following were required in order to present the discrete moving sound image as continuous movement. (1) The 3-D audio display system was required to complete the sound image presentation process, including head tracking and HRTF simulation, in a time shorter than 0.02 s, in order to present sound image movement at all velocities. (2) A processing time longer than 0.1 s was not acceptable. (3) If the 3-D audio display system only presented very slow movement (less than about 0.5 m/s), processing times ranging from 0.04 s to 0.06 s were still acceptable.
