Metallic Bond

Force that holds atoms together in a metallic substance. Such a solid consists of closely packed atoms. In most cases, the outermost electron shell of each of the metal atoms overlaps with a large number of neighbouring atoms. As a consequence, the valence electrons continually move from one atom to another and are not associated with any specific pair of atoms. In

Ear Disease

Ear diseases and hearing disorders are discussed in Michael E. Glasscock III, George E. Shambaugh, Jr., and Glenn D. Johnson (eds.), Surgery of the Ear, 4th ed. (1990), a well-illustrated text on diseases of the ear and their surgical correction; James Jerger (ed.), Hearing Disorders in Adults (1984); John Ballantyne, M.C. Martin, and Antony Martin (eds.), Deafness, 5th ed. (1993); Robert Thayer Sataloff and Joseph Sataloff, Hearing Loss, 3rd ed., rev. and expanded (1993); and David M. Vernick et al., The Hearing Loss Handbook (1993). George E. Shambaugh, “A Restudy of the Minute Anatomy of Structures in the Cochlea with Conclusions Bearing on the Solution of the Problem of Tone Perception,” The American Journal of Anatomy, 7(2):245–257 (Aug. 1, 1907), was the first detailed description of the hearing-nerve end organ in the cochlea, where sound waves are converted into nerve impulses depending upon the pitch of the tone. George E. Shambaugh, Jr., and Alexandre Petrovic, “Effects of Sodium Fluoride on Bone: Application to Otosclerosis and Other Decalcifying Bone Diseases,” JAMA, 204(11):969–973 (June 10, 1968), summarizes research on the arrest, by means of sodium fluoride, of progressive deafness caused by otosclerosis. Philip H. Beales, Noise, Hearing, and Deafness (1965), is a useful review in lay language of the problem of deafness and the adverse influence on hearing of excess noise exposure; a more recent text is Karl D. Kryter, The Handbook of Hearing and the Effects of Noise: Physiology, Psychology, and Public Health (1994). Brief reports by panels of experts assembled by the National Institutes of Health are issued as NIH Consensus Statements; several statements are of clinical concern in the field of hearing and deafness: “Noise and Hearing Loss,” 8(1):1–24 (Jan. 22–24, 1990), also available with the same title in JAMA, 263(23):3185–3190 (June 20, 1990), “Early Identification of Hearing Impairment in Infants and Young Children,” 11(1):1–24 (Mar. 1–3, 1993), and “Cochlear Implants in Adults and Children,” 13(2):1–30 (May 15–17, 1995), also available with the same title in JAMA, 274(24):1955–1961 (Dec. 27, 1995). More information on the success of cochlear implants is available in Jeffrey P. Harris, John P. Anderson, and Robert Novak, “An Outcomes Study of Cochlear Implants in Deaf Patients,” Archives of Otolaryngology—Head and Neck Surgery, 121(4):398–404 (April 1995).
