Download or read book Using the Auditory Hazard Assessment Algorithm for Humans AHAAH Software Beta Release W93e written by and published by . This book was released on 2009 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Auditory Hazard Analysis Algorithm for Humans (AHAAH) calculates the risk to human hearing of impulse noises, such as gunfire or airbag deployment. It achieves this by modeling the effects of the sound pressure wave from the free field, through the middle ear, and into the inner ear. The output of the algorithm is the number of auditory risk units (ARUs) associated with exposure to the given impulse sound. ARUs predict hearing damage; values over 500 ARUs for a 24-h exposure are likely to produce permanent hearing loss. The algorithm is implemented in computer software. This report is a user's manual for the AHAAH software release W93e.

This book was released on 2004-12-01 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The auditory hazard assessment algorithm for the human ear computer model developed at the U.S. Army Research Laboratory, Aberdeen Proving Ground, MD, was evaluated using data from human volunteer studies (conducted at Kirtland Air Force Base, Albuquerque, NM) sponsored by the U.S. Army Medical Research and Materiel Command, Ft Detrick, MD. Measurements of the exposure impulses made under the earmuffs of volunteers and the resulting temporary hearing losses were analyzed using the model. The model predictions were compared to the number of volunteers showing significant threshold shifts. For the six-impulse exposures, the model tended to predict more hazard than the human data showed. This over prediction of hazard at small numbers of impulses was exacerbated at larger numbers of impulses because of a rapid accumulation of predicted hazard with increasing numbers of impulses. The minimum phase procedure of the model for estimating the efficacy of hearing protection from real ear attenuation and insertion loss data was evaluated. The model predictions from the minimum phase calculations indicated higher risk than the measurements under the earmuffs. In general, the model hazard indications, from measured data and minimum phase calculations, were not in agreement with the results of the human studies.
Download or read book Designing Soldier Systems written by Dr Laurel Allender and published by Ashgate Publishing, Ltd.. This book was released on 2013-01-28 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on contemporary human factors issues within the design of soldier systems and describes how they are currently being investigated and addressed by the U.S. Army to enhance soldier performance and effectiveness. Designing Soldier Systems approaches human factors issues from three main perspectives. In the first section, Chapters 1-5 focus on complexity introduced by technology, its impact on human performance, and how issues are being addressed to reduce cognitive workload. In the second section, Chapters 6-10 concentrate on obstacles imposed by operational and environmental conditions on the battlefield and how they are being mitigated through the use of technology. The third section, Chapters 11-21, is dedicated to system design and evaluation including the tools, techniques and technologies used by researchers who design soldier systems to overcome human physical and cognitive performance limitations as well as the obstacles imposed by environmental and operations conditions that are encountered by soldiers. The book will appeal to an international multidisciplinary audience interested in the design and development of systems for military use, including defense contractors, program management offices, human factors engineers, human system integrators, system engineers, and computer scientists. Relevant programs of study include those in human factors, cognitive science, neuroscience, neuroergonomics, psychology, training and education, and engineering.
Download or read book Human Robot Interactions in Future Military Operations written by Florian Jentsch and published by CRC Press. This book was released on 2016-05-23 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soldier-robot teams will be an important component of future battle spaces, creating a complex but potentially more survivable and effective combat force. The complexity of the battlefield of the future presents its own problems. The variety of robotic systems and the almost infinite number of possible military missions create a dilemma for researchers who wish to predict human-robot interactions (HRI) performance in future environments. Human-Robot Interactions in Future Military Operations provides an opportunity for scientists investigating military issues related to HRI to present their results cohesively within a single volume. The issues range from operators interacting with small ground robots and aerial vehicles to supervising large, near-autonomous vehicles capable of intelligent battlefield behaviors. The ability of the human to 'team' with intelligent unmanned systems in such environments is the focus of the volume. As such, chapters are written by recognized leaders within their disciplines and they discuss their research in the context of a broad-based approach. Therefore the book allows researchers from differing disciplines to be brought up to date on both theoretical and methodological issues surrounding human-robot interaction in military environments. The overall objective of this volume is to illuminate the challenges and potential solutions for military HRI through discussion of the many approaches that have been utilized in order to converge on a better understanding of this relatively complex concept. It should be noted that many of these issues will generalize to civilian applications as robotic technology matures. An important outcome is the focus on developing general human-robot teaming principles and guidelines to help both the human factors design and training community develop a better understanding of this nascent but revolutionary technology. Much of the research within the book is based on the Human Research and Engineering Directorate (HRED), U.S. Army Research Laboratory (ARL) 5-year Army Technology Objective (ATO) research program. The program addressed HRI and teaming for both aerial and ground robotic assets in conjunction with the U.S. Army Tank and Automotive Research and Development Center (TARDEC) and the Aviation and Missile Development Center (AMRDEC) The purpose of the program was to understand HRI issues in order to develop and evaluate technologies to improve HRI battlefield performance for Future Combat Systems (FCS). The work within this volume goes beyond the research results to encapsulate the ATO's findings and discuss them in a broader context in order to understand both their military and civilian implications. For this reason, scientists conducting related research have contributed additional chapters to widen the scope of the original research boundaries.
