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 …

Problems With Auditory Alarms in Anesthesia and Tests of a Proposed Solution: Multimodal Multitask Performance With an Auditory Display
Auditory alarms are used pervasively for patient-monitoring equipment to warn of potential problems, despite widely reported shortcomings in their design. Problems include high rates of false alarms; interruptive, uninformative, stress-inducing acoustic profiles for alarm sounds; and alarms that …

Effects of Visibility and Alarm Modality on Workload, Trust in Automation, Situation Awareness, and Driver Performance
… of the present study is to determine whether auditory or tactile CAWS have a greater effect on driver performance, perceived workload, system trust, and situation awareness (SA). Sixty-three undergraduate students from Old Dominion University participated in this study. Participants were asked …

Evaluation of medical alarm sounds
Auditory alarms in medical equipments perform considerably below their optimal level. Concern has been expressed about the quality of medical alarms by a large number of researchers in recent years. A detailed literature survey on the medical alarm related problems has been carried out. Hospital …

Design and testing of a roadside traffic threat alerting mechanism
… preference. Two of these alarm prototypes were auditory sirens and two were haptic vibrations, one placed at the waist, and one at the wrist. Haptic vibrations, which we hypothesized would be more salient in a loud and visually stimulating environment, proved to induce statistically …

Effect of auditory peripheral displays on unmanned aerial vehicle operator performance
… integrate the continuous audio with other auditory alarms and visual representations in a display, as it is possible for discrete audio alerts to be masked by continuous audio, leaving operators reliant on the visual aspects of the display.

Multimodal Multitasking: The Combined Effects of Postural and Cognitive Demands on Overall Workload
… the product in some way, and react to visual and auditory alarms. Mistakes could be dangerous. It is clearly important, then, to understand the interactive effects of mental and postural workload. The goal of this research was to quantify the effects of mental and postural demands on overall …

Parkinsonian Speech and Voice Quality: Assessment and Improvement
… reliable voice activity detection, and visual/auditory alarms when the produced speech was below a certain threshold. Performance evaluation of this device in noisy environments demonstrated significant improvements in speech SNR, perceived intelligibility, and predicted quality, especially in …

The Bridging Technique: Crossing Over the Modality Shifting Effect
… an appropriate sensory modality (e.g., visual or auditory) (Sarter, 2006). For example, if an alarm is presented during a mission in a modality already highly taxed or overloaded, this can result in increased response time (RT), thereby decreasing operator performance (Wickens, 1976). To overcome …

Exploring the Influence of Anger on Takeover Performance in Semi-automated Vehicles
… the effects of increased perceived urgency of auditory alarms on takeover reaction time were measured. Data from this research was used to help test mathematical driver behavior modeling using the QN-MHP cognitive architecture. Using a motion-based simulator, 36 participants performed takeovers …
