Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.
Kids will enjoy learniing about the concept of sound waves in this entertaining book. Readers will learn how sound waves are used for communication and be able to demonstrate this knowledge by creating their own sound devices.
Examines advanced approaches to sound change from various theoretical and methodological perspectives, including articulatory variation and modeling, speech perception mechanisms and neurobiological processes, geographical and social variation, and diachronic phonology.
This volume showcases the current state of the art in phonologization research, bringing together work by leading scholars in sound change research from different disciplinary and scholarly traditions.
This book discusses the origins of a series of sound changes in English: it investigates their linguistic properties and social and cultural context to investigate why do sound changes happen when and where they do. Written with minimal use of jargon it will appeal to all serious students of English historical linguistics, from advanced undergraduates to researchers.
This is a thoroughly revised and expanded version of a book published earlier under the same title in 1972. It has been redrafted as an introductory text-book for students of linguistics by giving copious examples and also exercises and recommended readings. It has been prepared with students of the Indian subcontinent in mind, as the examples derive primarily from the languages (Dravidian, Indo-Aryan and Tibeto-Burman) of this area.
