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.

Including many simple exercises, interviews with experts, and potent, transformational concepts, this book is a practical guide to improving the vital personal communication skills of speaking and listening. --

An accessible guide to the practice of conscious humming • Details conscious humming and breathing exercises from simple to advanced, including online access to examples of these practices • Examines the latest studies on sound, revealing how humming helps with stress levels, sleep, and blood pressure, increases lymphatic circulation, releases endorphins, creates new neural pathways in the brain, and boosts blood platelet production • Explores the spiritual use of humming, including its use as a sonic yoga technique and its role in many world traditions • Includes access to online examples, allowing you to experience the powerful vibratory resonance that humming can create Humming is one of the simplest and yet most profound sounds we can make. If you have a voice and can speak, you can hum. Research has shown humming to be much more than a self-soothing sound: it affects us on a physical level, reducing stress, inducing calmness, and enhancing sleep as well as lowering heart rate and blood pressure and producing powerful neurochemicals such as oxytocin, the “love” hormone. In this guide to conscious humming, Jonathan and Andi Goldman show that you do not need to be a musician or singer to benefit from sound healing practices—all you need to do is hum. They provide conscious humming and breathing exercises from simple to advanced, complete with online examples, allowing you to experience the powerful vibratory resonance that humming can create and harness its healing benefits for body, mind, and spirit. They explore the science behind sound healing, revealing how self-created sounds can literally rearrange molecular structure and how humming not only helps with stress levels, sleep, and blood pressure but also increases lymphatic circulation and melatonin production, releases endorphins, creates new neural pathways in the brain, and releases nitric oxide, a neurotransmitter fundamental to health and well-being. The authors show how sound can act as a triggering mechanism for the manifestation of your conscious intentions. They also examine the spiritual use of humming, including its use as a sonic yoga technique and its role in many world traditions, such as the Om, Aum, or Hum of Hindu and Tibetan traditions. Providing a self-healing method accessible to all, the authors reveal that, even if you have no musical ability, we are all sound healers.

Sound is integral to how we experience the world, in the form of noise as well as music. But what is sound? What is the physical basis of pitch and harmony? And how are sound waves exploited in musical instruments? In this Very Short Introduction Mike Goldsmith looks at the science of sound and explores sound in different contexts, covering the audible and inaudible, sound underground and underwater, accoustic and electric, and hearing in humans and animals. He also considers the problem of sound out of place - noise and its reduction. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

The surprising science of hearing and the remarkable technologies that can help us hear better Our sense of hearing makes it easy to connect with the world and the people around us. The human system for processing sound is a biological marvel, an intricate assembly of delicate membranes, bones, receptor cells, and neurons. Yet many people take their ears for granted, abusing them with loud restaurants, rock concerts, and Q-tips. And then, eventually, most of us start to go deaf. Millions of Americans suffer from hearing loss. Faced with the cost and stigma of hearing aids, the natural human tendency is to do nothing and hope for the best, usually while pretending that nothing is wrong. In Volume Control, David Owen argues this inaction comes with a huge social cost. He demystifies the science of hearing while encouraging readers to get the treatment they need for hearing loss and protect the hearing they still have. Hearing aids are rapidly improving and becoming more versatile. Inexpensive high-tech substitutes are increasingly available, making it possible for more of us to boost our weakening ears without bankrupting ourselves. Relatively soon, physicians may be able to reverse losses that have always been considered irreversible. Even the insistent buzz of tinnitus may soon yield to relatively simple treatments and techniques. With wit and clarity, Owen explores the incredible possibilities of technologically assisted hearing. And he proves that ears, whether they're working or not, are endlessly interesting.
