How would persons with auditory agnosia respond to a broadcast without chimes for alert? To answer this question, two experiments were conducted: one with natural voice recordings made for “reading novels” without chimes, and the other with “visual stimuli and single digit arithmetic” without chimes. A total of 100 people participated in the experiment, 65 of whom had auditory agnosia and 35 of whom were non-impaired or unaware of their disability (henceforth, “nonimpaired”). The results of the experiment without chimes, and the previous experiment with chimes, found significant differences between the non-impaired and severely impaired people subjects with and without the chime. Assuming the non-impaired persons understood the linguistic meaning with a minimum score or better, about 25 % of the mildly- and about 25 % of the severelyimpaired subjects understood the linguistic meaning without chimes, whereas in the experiment with chimes, more than 50 % of the mildly- and about 25 % of the severely-impaired subjects understood the natural voice linguistic meaning. It was demonstrated that with the addition of chimes, more persons with auditory agnosia can understand the linguistic meaning of a disaster broadcast.
