Does reverberation affect upper limits for auditory motion perception?
MetadataShow full item record
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.
