Hearing loss is insidious in its presentation but devastating in its personal, family, and social impact. The sense of hearing is a means of communication for human beings and helps them keep in touch with reality. Hearing impairment can hinder the communication with others and diminishes the individual's aesthetic enjoyment of major aspects of daily living and can adversely affect the quality of life. A quasiexperimental pre- and posttest control group design was chosen for this study. By using nonprobability purposive sampling technique, 60 samples were selected in which 30 samples were assigned to experimental and 30 to the control groups. The findings show that in the experimental group, the posttest mean score of knowledge was 20.9 with standard deviation (SD) 2.07, whereas in the control group, the posttest mean score was 6.87 with SD 1.69. The calculated “t” test value t = 28.689 was found to be statistically significant at p < 0.001 level that clearly shows that the self-instructional module on knowledge of aural rehabilitation was effective.
