Noise And Military Service

The Institute of Medicine carried out a study mandated by Congress and sponsored by the Department of Veterans Affairs to provide an assessment of several issues related to noise-induced hearing loss and tinnitus associated with service in the Armed Forces since World War II. The resulting book, Noise and Military Service: Implications for Hearing Loss and Tinnitus, presents findings on the presence of hazardous noise in military settings, levels of noise exposure necessary to cause hearing loss or tinnitus, risk factors for noise-induced hearing loss and tinnitus, the timing of the effects of noise exposure on hearing, and the adequacy of military hearing conservation programs and audiometric testing. The book stresses the importance of conducting hearing tests (audiograms) at the beginning and end of military service for all military personnel and recommends several steps aimed at improving the military services' prevention of and surveillance for hearing loss and tinnitus. The book also identifies research needs, emphasizing topics specifically related to military service.

The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

The overview and details of the common condition of tinnitus are covered for audiology, speech and language science students. Beginning with epidemiology, including classification, incidence in various populations and etiology, the volume also addresses the psychological profile of tinnitus patients. In addition the effects of tinnitus on lifestyle, employment, relationships and communicaiton are included. Briefings cover insomnia, physiological and neural mechanisms, evaluation, management, surgery and childhood tinnitus. Therapy and treatment modalities are presented in detail.

Exposure to hazardous noise can have negative implications for both servicemember health and readiness. Moreover, in FY 2009, some of the most common impairments for veterans receiving Veterans Affairs (VA) disability benefits were hearing related, as annual payments for such conditions exceeded $1.1 billion. This report examined DoD efforts to prevent hearing loss, specifically: (1) how well the DoD and armed services identify and mitigate hazardous noise; (2) how well the military evaluates hearing conservation program performance; and (3) the status of DoD's Hearing Center of Excellence and the extent that DoD and VA are sharing information to inform this and other efforts. Includes recommend. Charts and tables. This is a print on demand report.

This book is about how you listen and what you hear, about how to have a dialogue with the sounds around you. Marcia Jenneth Epstein gives readers the impetus and the tools to understand the sounds and noise that define their daily lives in this groundbreaking interdisciplinary study of how auditory stimuli impact both individuals and communities. Epstein employs scientific and sociological perspectives to examine noise in multiple contexts: as a threat to health and peace of mind, as a motivator for social cohesion, as a potent form of communication and expression of power. She draws on a massive base of specialist literature from fields as diverse as nursing and neuroscience, sociology and sound studies, acoustic ecology and urban planning, engineering, anthropology, and musicology, among others, synthesizing and explaining these findings to evaluate the ubiquitous effects of sound in everyday life. Epstein investigates speech and music as well as noise and explores their physical and cultural dimensions. Ultimately she argues for an engaged public dialogue on sound, built on a shared foundation of critical listening, and provides the understanding for all of us to speak and be heard in such a discussion. Sound and Noise is a timely evaluation of the noise that surrounds us, how we hear it, and what we can do about it.
