DURlNG the past decade, research in hearing and speech impairments has attained prodigious proportions. A good ideal of the impetus for this research was provided by the armed forces in the development of the Army and Navy rehabilitation programs for hearing and speech casualties. The Army and Navy provided funds and utilized key institutions and personnel in developing instrumentation, materials, and procedures for successful prosecution of their programs. Even after the conclusion of the war, the Army and Navy not only manifested continued interest in such research and service, but also made available to institutions and individuals the bulk of this research which formerly fell into restricted categories. Concomitantly, educational and service agencies thruout the country expanded their facilities for exceptional children and adults (2, 4). Because of the extremely large number of contributions appearing since the last review by Johnson and Gardner (69), selection could only include a limited number of these references.Some of these contributions cover wide areas of research themselves. The research of Davis (25), Licklider (81, 82), Miller (95, 96), von Békésy (141), and Wever (149) has penetrated the frontiers of psycho-acoustics, psychophysiology, and other audition phenomena to amazingly profound depths. Jacobson (66) reported the informational capacity of the human ear depended little on its dynamic range. He further considered methods of informational match to the ear, and calculated the average capacity of 0.3 bit/sec. for an individual cochlear fiber. Davis (24) proposed that the Gabor Information Diagram approximated the characteristics of the human ear better than the wave-form or frequency-spectrum methods of representation. Miller and others (97) compiled a two-volume bibliography in audition covering approximately 5500 references. Bangs (7), Curry (22)
