Download or read book Hearing Conservation written by Vishakha Rawool and published by Thieme. This book was released on 2011-09-19 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to the National Institutes of Occupational Safety and Health, approximately 30 million employees are exposed to dangerous noise levels at work and an additional nine million workers are at risk for hearing loss from other ototoxins such as metals and solvents. Millions of children and young adults are also at risk for noise-induced hearing loss in non-occupational settings. Hearing Conservation: In Occupational, Recreational, Education, and Home Settingsis the most current text to cover all major topics related to noise-induced hearing loss, including the military, construction, manufacturing, mining, transportation, the music industry, the home environment, education settings, and recreational arenas. From the underlying principles of hearing loss to audiometric testing procedures to assessment of hearing conservation programs, this book is packed with information for audiologists and other members of the interdisciplinary team who provide hearing conservation services for at-risk groups.Special Features: Many examples of audiometric data, that enhance understanding of all types of hearing impairment, test procedures, and standard threshold shift calculations Protocols for comprehensive audiological, tinnitus, and auditory processing evaluations Clinical pathways and follow-up action steps when a standard threshold shift is confirmed, including decisions about worker compensation in occupational settings Assessment of the effectiveness of a wide range of hearing conservation programs and correction of deficiencies, along with training, educational, and motivational techniques The most current information about hearing protection and enhancement devices, related regulations, selection and fitting, and training workers in how to use them for optimal results A set of discussion questions at the end of each chapter that stimulate review and classroom dialogue Comprehensive in scope, easily accessible, and useful to both clinicians and investigators,Hearing Conservation: In Occupational, Recreational, Education, and Home Settings is essential for audiologists, occupational hearing conservationists, otolaryngologists, internists, occupational nurses, noise control engineers, and any other practitioner who plays a role in developing, implementing, and maintaining hearing conservation measures. It is also an excellent text for graduate level audiology courses in hearing conservation.
Download or read book Hearing Protection and Speech Intelligibility of Two Nonstandard Inflight Communication Headsets written by A. M. Prohaska and published by . This book was released on 1984 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the hearing protection and voice communications effectiveness of two standard earmuff hearing protectors modified to function as voice communications headsets. Both modified units contained the AF standard H-143 inflight receivers and the M-87 noise cancelling boom microphone. Hearing protection and voice communication performance of the modified units were compared to those of the H-157 headset at four intensity levels of a noise spectrum that was generally flat from 63 Hz to 5000 Hz (80, 95, 105, 115 dB 20 microPa. The results showed that the H-157 headset provided more hearing protection than either of the modified headsets, especially in the higher frequencies. The modified headsets provided better speech intelligibility than the H-157 headset. Wearability problems were noted with the modified headsets which may become a problem in the operational situation. (Author).

This book was released on 2007 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Communication in military settings must be clear and understandable to avoid possible fatal accidents and mistakes. Speech intelligibility is the overall quality of speech that makes it comprehensible. Intelligibility of speech depends on the properties of the talker, transmission channel, and the listener. The purpose of the reported study was to evaluate intelligibility of speech provided by five communication and hearing protection systems (C&HPSs) operating in talk-through mode. The systems evaluated in this study were the Product Improved-Combat Vehicle Crewman's (PI-CVC) helmet, Bose Improved Tactical Headset (ITH), Mine Safety Appliances-Sordin Gen II headset (Gen II), Communications Enhancement and Protection System (CEPS), and Combat Arms Earplugs (CAE). All systems except for the first one were worn with the Advanced Combat Helmet (ACH). The baseline conditions for assessing the communication data were bare head and the ACH worn alone. Results show that the ACH only, PI-CVC, and Gen II conditions provided significantly better speech intelligibility than the CAE and CEPS for the listeners participating in the study. Performance data for the ITH condition fell between the two groupings. Overall, the earplug-based communication systems (CAE and CEPS) resulted in lower performance and larger data variability than the earmuff-based systems. This larger variability could be attributed to poor repeatability in earplug insertion, which may be limited through more extensive training.
