Book Description
Hearing, health, and technologies are entangled in multi-faceted ways. This edited volume addresses this complex relationship by arguing that modern hearing was and is increasingly linked to and mediated by technological innovations. By providing a set of original interdisciplinary investigations that shed new light on the history, theory, and practices of hearing techniques, it is able to explore the heterogeneous entanglements of sound, hearing practices, technologies, and health issues. As the first book to bring together historians, scholars from media studies, social sciences, cultural studies, acoustics, and neuroscientists, the volume discusses modern technologies and their decisive impact on how "normal" hearing, enhanced and smart hearing, as well as hearing impairment have been configured. It brings both new insights into the histories of hearing technologies as well as allowing us to better understand how enabling hearing technologies have currently been unfolding an increasingly hybrid ecology engaging smart hearing devices and offering stress-free hearing and acoustic well-being in novel auditory environments. The volume will be of interest to all scholars and students of disability studies, sound studies, sociology of health and illness, medical history, health and society, as well as those interested in the practices and techniques of self-monitored and smart hearing.

Book Description
The loss of hearing - be it gradual or acute, mild or severe, present since birth or acquired in older age - can have significant effects on one's communication abilities, quality of life, social participation, and health. Despite this, many people with hearing loss do not seek or receive hearing health care. The reasons are numerous, complex, and often interconnected. For some, hearing health care is not affordable. For others, the appropriate services are difficult to access, or individuals do not know how or where to access them. Others may not want to deal with the stigma that they and society may associate with needing hearing health care and obtaining that care. Still others do not recognize they need hearing health care, as hearing loss is an invisible health condition that often worsens gradually over time. In the United States, an estimated 30 million individuals (12.7 percent of Americans ages 12 years or older) have hearing loss. Globally, hearing loss has been identified as the fifth leading cause of years lived with disability. Successful hearing health care enables individuals with hearing loss to have the freedom to communicate in their environments in ways that are culturally appropriate and that preserve their dignity and function. Hearing Health Care for Adults focuses on improving the accessibility and affordability of hearing health care for adults of all ages. This study examines the hearing health care system, with a focus on non-surgical technologies and services, and offers recommendations for improving access to, the affordability of, and the quality of hearing health care for adults of all ages.

Book Description
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.

Book Description
A self-training manual as well as a classroom text, this book is a complete step-by-step course to develop the musician's ability to hear and notate any style of music. Personal training, thoery and exercises produce techniques which are combined in an integrated craft which may be applied to composition, orchestration, arranging, improvisation and performance. A kind of finishing school for those who wish to pursue a career in composing, orchestrating, arranging or performing. -- The Score, Society of Composers and Lyricists A myriad of practical information. Comprehensive ear training, important because aural skills are among the most overlooked in music education. -- Survey of New Teaching Materials, Jazz Educators journal A synthesis of the author's vast knowledge and his quest to define the question, "How do we hear?" -- ITG Journal A wonderfully systematic approach to ear training . . . neatly designed and structured, it just flows. Direct and easily understood. -- New books, Jazz Educators Journal Bernard Brandt says: "Hearing and Writing Music", by Ron Gorow, is a superb book. It makes a simple and elegant presentation of the internal process by which we hear sounds and music, how we recognize intervals, chords, melody, harmony, counterpoint, and the timbre of instrumentation/ orchestration, how we can develop the skills of listening, auditory memory and imagination, and how to use these skills to hear and to write down music of any sort. The hallmark of an expert is the ability to explain the basics of his field as simply as possible. By that standard, Mr. Gorow has proven his expertise in this book. I note that the other reviews, both for Amazon and in musical journals, tend to limit the importance of "Hearing and Writing Music" to ear training. I believe that Mr. Gorow's book is valuable for much more than ear training. I have studied it, and as a result of that study, I believe that my auditory memory and imagination and my abilities in score reading have improved enormously. Further, I have been able to use the skills in this book to transcribe melodies, harmonies and counterpoint almost effortlessly, both those that I have heard, and those which existed only in my imagination. This book has opened many doors for me. I believe that it can do so for many others.
