Hearing Loss


Book Description

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.

May Human Beings Hear It!


Book Description

During the Christmas period of 1923-4, Rudolf Steiner refounded the Anthroposophical Society at its headquarters in Dornach, Switzerland. This important event, which has come to be known as the Christmas Conference, can be studied on many levels, and its many mysteries have been central to Sergei O. Prokofieff's anthroposophical research over the years. His beginning point has been an enduring question: What did Rudolf Steiner mean when he called the Christmas Conference the ‘start of a World-Turning-point of Time’? In this far-reaching work, the author – working from several different viewpoints - guides the reader towards an answer. Prokofieff suggests that the impulse of the Christmas Conference can only be reenlivened today through conscious action by individuals to experience its spiritual essence. Rather than offering dogmatic conclusions, he opens up paths of approaching this goal by throwing light on different aspects of the Conference and what lies at its heart: the Foundation Stone and its Meditation. In particular, Prokofieff explores three key perspectives: the connection of the Christmas Conference with humanity’s evolution; the inner relationship of each individual anthroposophist to the Christmas Conference; and the significance of the Conference to Rudolf Steiner himself. Although this is major work of some length, the individual chapters of May Human Beings Hear It! are complete in themselves, and can therefore be studied independently of each other.
