Download or read book Underwater Noise and the Conservation of Divers' Hearing: A Review written by and published by . This book was released on 1989 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: A critical review of past research conducted on underwater hearing, particularly on underwater thresholds of audibility, has revealed that current underwater noise exposure limits may be too lax. Further new experimental work at suprathreshold sound levels also supports the need to lower current underwater permissible noise exposure values. A new approach to establishing an underwater noise exposure standard is proposed. Information is provided on the hearing protection provided by divers' hoods. Some tutorial information is also provided on the anatomy and functioning of the ear, on sound level reference values, and on the means to convert in-air audiometric data to equivalent in-air sound field data for comparison with underwater sound field data. Keywords: Underwater hearing; Underwater thresholds of audibility; Underwater noise; Hearing protection provided by divers' hoods; Hood acoustic attenuation; Underwater acoustic reflex thresholds; Equal loudness comparison (air vs water); Sound level reference values; Minimum Audible Field (MAF); Minimum Audible Pressure (MAP); Minimum Audible Pressure as Measured by a Standard Coupler (MAPC); Audio-metric standards; Temporary Threshold Shifts (TTS); Spectral weighting underwater; Permissible exposure levels underwater.
Book Synopsis Hearing and Underwater Noise Exposure by : Paul F. Smith
Download or read book Hearing and Underwater Noise Exposure written by Paul F. Smith and published by . This book was released on 1985 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exposure of divers to intense noise in water is increasing, yet there is no general hearing conservation standard for such exposures. This paper reviews three theories of underwater hearing as well as empirical data in order to identify some requirements that an underwater conservation standard must meet. Among the problems considered are hearing sensitivity in water, the frequency and dynamic ranges of the water-immersed ear, and nonauditory effects of underwater sound. It is concluded that: first, no well developed theoretical basis exists for extrapolating hearing conservation standards for airborne noise to the underwater situation; second, the empirical data on underwater hearing suggest that the frequency range covered by an underwater hearing conservation standard must be broader than is the case in air; third, in order to establish a general hearing conservation standard for underwater noise exposure further research is required on the dynamic range of the ear in water; fourth, underwater noise exposure may involve hazards to other body systems than the ear; and fifth, some exposure conditions may interfere with job performance of divers. Keywords: Deafness, Sonar, Noise, Sound, Ultrasound, Infra-sound, Stress(Physiological), Hazards, Diving.

Book Synopsis Medical-Legal Evaluation of Hearing Loss, Third Edition by : Robert A. Dobie
Download or read book Medical-Legal Evaluation of Hearing Loss, Third Edition written by Robert A. Dobie and published by Plural Publishing. This book was released on 2015-07-15 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Medical-Legal Evaluation of Hearing Loss, Third Edition includes the most accurate and current developments in the field with more than 250 new references. A comprehensive guide on hearing loss and the law, it examines claims, court cases, and the evolution of hearing conservation. This text addresses age-related hearing loss, genetics of hearing loss, and noise-induced hearing loss (NIHL) - with a newly revised international standard (ISO-1999, 2013) that presents a comprehensive predictive model for NIHL, critical in medical-legal evaluation. Also examined is hearing loss due to toxins, trauma, and disease, as well as the effects of cardiovascular risk factors, race, and socioeconomic status. Furthermore, included tutorial discussions of acoustics, hearing, and hearing testing will be valuable to attorneys and other nonclinicians. New or expanded topics include: The relationship of hearing loss to brain disordersJob fitnessAccommodations under the Americans with Disabilities ActBlast injuryRecreational music and hearing lossHypothesis of progressive NIHL after noise cessationSolvent ototoxicityAppropriate exchange rate for predicting noise hazardThe American Medical Associations method of measurement of hearing disability This new edition provides practical guidance for expert witnesses and legal practitioners and is essential for otolaryngologists, audiologists, occupational physicians, attorneys handling hearing loss claims, and claims management professionals.

Download or read book Effects of Anthropogenic Noise on Animals written by Hans Slabbekoorn and published by Springer. This book was released on 2018-08-20 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past several years, many investigators interested in the effects of man-made sounds on animals have come to realize that there is much to gain from studying the broader literature on hearing sound and the effects of sound as well as data from the effects on humans. It has also become clear that knowledge of the effects of sound on one group of animals (e.g., birds or frogs) can guide studies on other groups (e.g., marine mammals or fishes) and that a review of all such studies together would be very useful to get a better understanding of the general principles and underlying cochlear and cognitive mechanisms that explain damage, disturbance, and deterrence across taxa. The purpose of this volume, then, is to provide a comprehensive review of the effects of man-made sounds on animals, with the goal of fulfilling two major needs. First, it was thought to be important to bring together data on sound and bioacoustics that have implications across all taxa (including humans) so that such information is generally available to the community of scholars interested in the effects of sound. This is done in Chaps. 2-5. Second, in Chaps. 6-10, the volume brings together what is known about the effects of sound on diverse vertebrate taxa so that investigators with interests in specific groups can learn from the data and experimental approaches from other species. Put another way, having an overview of the similarities and discrepancies among various animal groups and insight into the “how and why” will benefit the overall conceptual understanding, applications in society, and all future research.
