The Encyclopedia of Deafness and Hearing Disorders (Facts on File Library of Health & Living)

More than 28 million Americans are deaf or hard-of-hearing. One in ten has some degree of hearing loss. Although hearing people consider the deaf to be handicapped, the deaf community is, in fact, a separate and rich culture with a wide range of institutions that help its members lead full lives in a hearing world.The Encyclopedia of Deafness and Hearing Disorders, first published in 1991, has been revised by the authors. Turkington, a medical writer, and Sussman, a professor and counselor at Gallaudet University, provide the latest information about hearing impairment and its treatment. More than 800 alphabetical entries cover such topics as parts of the ear (Cochlea), clinical terms (Delayed auditory feedback ), individuals (Beethoven, Ludwig van ; Keller, Helen Adams ), devices and equipment (Telecommunications device for the deaf ), diseases and conditions (Auditory neuritis, Tinnitus ), and institutions and organizations (Gallau det University, Institut National des Sourds ).
