“…Therefore, an auditory perception experiment was carried out to obtain an effective length for which bicyclists will perceive the presence of a vehicle behind them. Barnecutt and Pfeffer (1998) states the difficulty and inaccuracy in estimating distance from loudness of sound. Nevertheless, the experiment herein is to determine when a vehicle sound is heard and not the intensity of it.…”

This research studies relevant factors in mixed traffic that may impact bicycling comfort in Ottawa, Canada. The observations are: [i] the average position of bicyclists from the curb is 0.57m, and lesser (i.e. 0.35m) in the presence of parking; [ii] bicyclists ride slightly further from curbs for two lanes in travel direction compared to single lanes; [iii] 90% of passes exceed 1.23m; [iv] lateral spacing between bicycles and vehicles (passing distance, PD) is positively correlated to motor vehicle speed, lane width, and bicyclist position from adjacent curb edge line, whiles inversely correlated to ambient traffic density and bicycle speed; [v] motor speed has the highest prediction of PD variability. Two linear regression models for PD and Comfort perception were developed, both exhibiting limited predictive power similar to Love et al. (2012) and Stewart and McHale (2014). Residual plots and significance of included variables are however indicative of correct model assumptions.

“…A number of studies have psycho-physically examined the acuity of absolute auditory depth perception 29,33,[37][38][39][40][41] and relative auditory depth perception. [42][43][44][45][46][47] Literature addressing absolute auditory depth perception far outweighs that addressing relative auditory depth perception. This is perhaps surprising, as sounds are rarely heard in isolation.…”

3D sound and 3D image interactions: a review of audio-visual depth perception

2014

There has been much research concerning visual depth perception in 3D stereoscopic displays and, to a lesser extent, auditory depth perception in 3D spatial sound systems. With 3D sound systems now available in a number of different forms, there is increasing interest in the integration of 3D sound systems with 3D displays. It therefore seems timely to review key concepts and results concerning depth perception in such display systems. We first present overviews of both visual and auditory depth perception, before focussing on cross-modal effects in audio-visual depth perception, which may be of direct interest to display and content designers.

“…For instance, Barnecutt and Pfeffer [1995] investigated auditory distance perception in traffic. Apart from level differences, they suggest that nonauditory criteria, like past experience or visual imagery, are so important factors for auditory interpretation.…”

Audio rendering is generally used to increase the realism of virtual environments (VE). In addition, audio rendering may also improve the performance in specific tasks carried out in interactive applications such as games or simulators.In this article we investigate the effect of the quality of sound rendering on task performance in a task which is inherently vision-dominated. The task is a virtual traffic gap-crossing scenario with two elements: first, to discriminate crossable and uncrossable gaps in oncoming traffic, and second, to find the right timing to start crossing the street without an accident. A study was carried out with 48 participants in an immersive virtual environment setup with a large screen and headphones. Participants were grouped into three different scenarios. In the first one, spatialized audio rendering with head-related transfer function (HRTF) filtering was used. The second group was tested with conventional stereo rendering, and the remaining group ran the experiment in a mute condition. Our results give a clear evidence that spatialized audio improves task performance compared to the unimodal mute condition. Since all task-relevant information was in the participants' field-of-view, we conclude that an enhancement of task performance results from a bimodal advantage due to the integration of visual and auditory spatial cues.
