Humans receive the vast majority of sensory perception through the eyes and ears. This non-technical book examines the everyday physics behind hearing and vision to help readers understand more about themselves and their physical environment. It begins wit

The widespread presence of jazz and blues in African American visual art has long been overlooked. The Hearing Eye makes the case for recognizing the music's importance, both as formal template and as explicit subject matter. Moving on from the use of iconic musical figures and motifs in Harlem Renaissance art, this groundbreaking collection explores the more allusive - and elusive - references to jazz and blues in a wide range of mostly contemporary visual artists. There are scholarly essays on the painters Rose Piper (Graham Lock), Norman Lewis (Sara Wood), Bob Thompson (Richard H. King), Romare Bearden (Robert G. O'Meally, Johannes Völz) and Jean-Michel Basquiat (Robert Farris Thompson), as well an account of early blues advertising art (Paul Oliver) and a discussion of the photographs of Roy DeCarava (Richard Ings). These essays are interspersed with a series of in-depth interviews by Graham Lock, who talks to quilter Michael Cummings and painters Sam Middleton, Wadsworth Jarrell, Joe Overstreet and Ellen Banks about their musical inspirations, and also looks at art's reciprocal effect on music in conversation with saxophonists Marty Ehrlich and Jane Ira Bloom. With numerous illustrations both in the book and on its companion website, The Hearing Eye reaffirms the significance of a fascinating and dynamic aspect of African American visual art that has been too long neglected.

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.

Based on careful analysis of burden of disease and the costs ofinterventions, this second edition of 'Disease Control Priorities in Developing Countries, 2nd edition' highlights achievable priorities; measures progresstoward providing efficient, equitable care; promotes cost-effectiveinterventions to targeted populations; and encourages integrated effortsto optimize health. Nearly 500 experts - scientists, epidemiologists, health economists,academicians, and public health practitioners - from around the worldcontributed to the data sources and methodologies, and identifiedchallenges and priorities, resulting in this integrated, comprehensivereference volume on the state of health in developing countries.

A neurobiologist reexamines the personal nature of perception in this groundbreaking guide to a new model for our senses. We think of perception as a passive, mechanical process, as if our eyes are cameras and our ears microphones. But as neurobiologist Susan R. Barry argues, perception is a deeply personal act. Our environments, our relationships, and our actions shape and reshape our senses throughout our lives. This idea is no more apparent than in the cases of people who gain senses as adults. Barry tells the stories of Liam McCoy, practically blind from birth, and Zohra Damji, born deaf, in the decade following surgeries that restored their senses. As Liam and Zohra learned entirely new ways of being, Barry discovered an entirely new model of the nature of perception. Coming to Our Senses is a celebration of human resilience and a powerful reminder that, before you can really understand other people, you must first recognize that their worlds are fundamentally different from your own.

Deaf people in New Zealand are often little known outside their own culture. People of the Eye brings their world to life in personal histories translated into English with a series of photographs of the deaf community. The storytellers are both old and young, and they reflect both the diversity and commonality of deaf experience; the painful lives of a generation brought up forbidden to use sign language contrasted with the confidence of young people using New Zealand Sign Language as they attend school and assert "deaf pride." The differences between children growing up in deaf families and those who struggle with identity as deaf children in hearing families are illuminating. These are stories of joy and sadness, confusion and resolution, and regret and optimism.

Ruth Silvers young life was challenged in ways most of us will never know. A silent, frightened child with undiagnosed vision loss, her world was one of limited vision that ultimately became one of total darkness. Once the situation had a nameretinitis pigmentosa (RP), a progressive eye diseaseshe at least knew what she was dealing with. As she grew, her other contact with the worldsoundwas also taken from her. Where others might have given up, Ruth refused to surrender to the darkness and silence. As Ruth Silvers world shrank around her, her heart and ambition grew. She never stopped looking for ways to add meaning to her life. Inspired by her own experiences and challenges, she founded the Center for Deaf-Blind Persons in Milwaukee, a nonprofit agency dedicated to helping others living with the double disability of deaf-blindness. Ruths story demonstrates how a resilient spirit can propel a profoundly disabled person forward toward a happy, productive life. A charming young man by the name of Marv was destined to change her life even more; their enduring love story is one of hope, patience, and acceptance. Invisible dispels myths, suggests useful teaching procedures, gives hope to people who are disabled and their families, and offers reassurance through her example that a person with profound disabilities can live a full, rich life.
