Abstract

Introduction: This article examines the effects of hearing level on individuals with congenital blindness. The study investigates variations in hearing thresholds and explores the relationship between hearing level and visual acuity among the participants. Methodology: The data were collected through audiometric examinations, visual acuity assessments, and self-reported measures. The study is conducted at the Government Secondary School for Congenital Blinds in Bahawalpur. A total of 50 participants, consisting of 33 females and 17 males, are included in the study. The participants are 7-12-year-old children with congenital blindness, specifically those with vision less than 3/60. Result:  The findings reveal variations in hearing sensitivity among individuals with congenital blindness, with some participants demonstrating enhanced auditory sensitivity in specific frequency ranges. However, the study does not find consistent evidence to support the perception that hearing level universally increases after the loss of sight. Visual acuity remains largely unaffected by hearing loss levels, with the majority of participants exhibiting normal visual acuity. These results highlight the complexity of sensory perception in individuals with congenital blindness and emphasize the importance of considering individual differences and subjective experiences. Conclusion: The study provides insights into the sensory profiles of individuals with congenital blindness, contributing to the understanding of their unique sensory experiences and informing future interventions and support strategies tailored to their specific needs.
