Aiding the Theater Patron Who is Hard of Hearing
From available data on the acuity of hearing of various groups of people, a chart is constructed showing the estimated distribution of any large group according to their hearing ability. Articulation vs. loudness curves are used to determine the amount of aid possible for any particular degree of deafness. From these sources it is estimated that approximately 10 per cent of the population who now cannot hear sound pictures satisfactorily can, with benefit, use a theater-hearing-aid system which reproduces without distortion; this number is reduced correspondingly with the amount of distortion introduced. The requirements of such a system are outlined and the Western Electric theater-hearing-aid attachment is described in detail.
