Abstract
Presented at the 21st International Conference on Auditory Display (ICAD2015), July 6-10, 2015, Graz, Styria, Austria.We report three experiments measuring the upper limits, defined
as auditory velocity thresholds beyond which listeners are no
longer able to perceptually resolve a smooth circular trajectory in
various reverberate conditions. These thresholds were measured
for white noise, band-limited white noise and band-limited white
noise mixed with a pure tone, in different reverberation conditions:
acoustically dry room, two simulated source-image-based reverberations
and natural reverberation with different configurations
of loudspeaker arrays. Experiment 1 took place in a dry room and
thresholds were measured with and without a reverberation simulation
of an actual reverberant room. In Experiment 2, various
simulated reverberation parameters were tested in the same dry
room, and two different loudspeaker configurations were tested in
a reverberant room. Experiment 3 investigated the effect of audio
source type in simulated reverberation condition and for high
velocities. No significant effects were observed among reverberation
conditions, suggesting that the upper limit is robust against
reverberation
