Abstract: This paper deals with certain aspects of the intricate relationship between the nature of hearing loss associated with various stages of impairment for hearing speech in everyday situations and the possibilities of improving physical therapy for the deafened through improvements in the design of hearing aids. The data, upon which the study is based, were obtained during a clinical study of deafness and aural disease conducted by the United States Public Health Service during the spring and summer of 1936. Variations in the nature of hearing loss are shown for persons having the following stages of practical handicaps for hearing speech in everyday situations: (a) impairment for hearing at church, in the theater, and in group conversation; (b) impairment for hearing conversation at close range; (c) impairment for hearing over the telephone; and (d) inability to hear speech under any circumstances.
