Auditory displays have been implemented with some success in a variety of in-vehicle technologies. Most of these applications have used discrete alerts and warnings, which present complications with false alarms and annoyance. Some research has suggested that on-going, continuous information displays may mitigate some of the problems with discrete alerts and warnings. We argue that well-designed naturalistic soundscapes offer a potentially useful means of continuous auditory display for in-vehicle technologies. We present examples of use scenarios and demonstrations of candidate sound manipulations for conveying information with soundscapes. We argue that soundscapes could be used in a variety of in-vehicle technologies, including displays of vehicle and driver conditions, collision and hazard warnings, infotainment systems, and automated systems.
