An Investigation into the Perceived Urgency of Auditory Warnings
… urgency of sound, with specific reference to auditory warning design. Psychophysical techniques were investigated as a means of measuring perceived urgency. The biases inherent in different techniques were reviewed. Free modulus magnitude estimation, fixed modulus magnitude estimation, …

Effects of Haptic and Auditory Warnings on Driver Intersection Behavior and Perception
… number of intersection-related crashes, haptic warnings and a combined haptic/auditory warning were explored and compared to combined visual/auditory warnings. The first phase of this study determined which haptic brake pulse warning candidate most often resulted in the driver successfully …

Auditory Alarms In The Intensive Care Unit: Experimental And Observational Studies
… are many problems associated with the number of auditory warnings in hospital environments such as the Intensive Care Unit. As the amount of medical technology used to monitor a patient's condition increases, there is a concomitant increase in the number of auditory warnings. Each piece of …

A Simulator-Based Investigation of Visual, Auditory, and Mixed-Modality Display of Vehicle Dynamic State Information to Commercial Motor Vehicle Operators
… study examined the use of conventional auditory warnings (tonal, non-verbal sounds) and auditory icons> (representational non-verbal sounds), alone and in combination with a dash-mounted visual display, to present information about impending collision situations to commercial motor …

The impact of White Shark (Carcharodon carcharias) sightings and attacks on recreational water use patterns in False Bay
… of water users. The response of water users to warnings of shark presence by the Shark Spotters was only found to be significant in cases where the siren was sounded by the shark spotters, and in the absence of a siren warning flags had little impact on average numbers of water users. The …

The perceived urgency and detection time of multi-tone and frequency-modulated warning signals in broadband noise
… and its situational urgency. In addition, many auditory warnings are not detectable within their environments. This research examined several prominent pulse parameters which affect the perceived urgency and detection time of auditory warning signals. These elements included pulse format …

The Effects of Vehicle Automation Level and Warning Type on Responses to Vehicle Hacking
… on the driver-vehicle interactions. In addition, auditory warnings have been shown to effectively attract a driver’s attention while performing a driving task, which is often visually demanding. The purpose of the current study was to examine the effect of level of automation and warning type on …

Empirical Studies Concerning Aural Alerts for Cockpit Use Leading to an Aural Alerting Signal Categorization Scheme
The only way to simplify and promote the effective use of an alerting system that must be comprehensive in its coverage of hazardous or non-normal conditions is to convey top level information that provides an indication of criticality and identity. In an attempt to reduce the number of aural …

An Investigation of Auditory Icons and Brake Response Times in a Commercial Truck-Cab Environment
… to the potential overload of the visual channel. Auditory icons have been shown to improve operator performance and decrease learning and response times, not only in industrial applications, but also as emergency braking warnings. The use of auditory icons in commercial truck cabs has the …

An evaluation of the urgency, similarity, and identification of aural alerts with implications for flight deck use
The only way to simplify and promote the effective use of an alerting system that must be comprehensive in its coverage of hazardous or non-normal conditions is to convey top level information that provides an indication of criticality and identity. In order to prevent the continued proliferation …
