Background: Sudden sensory neural hearing loss can be caused by many factors. It may range from minimal to profound degree of hearing loss. Barotrauma is a type of ear damage caused by pressure difference between the atmosphere and the inner ear. This may result in permanent sensory neural hearing loss. Objective: The aim of the study was to use behavioral and electrophysiological assessments to analyze the hearing of a patient who experienced sudden hearing loss following a dive in well. Case Report: A 31 year old male adult who reported sudden hearing loss following a dive in the well was evaluated. Hearing assessment was done. Pure tone audiometry revealed bilateral profound hearing loss. Immittance audiometry showed ‘A’ type tympanogram in both ears and acoustic reflexes absent in both ears. In ABR click stimulus test, no responses were observed till 105dBnHL in both ears. DPOAE’s were also absent in both ears. Vestibular assessments (subjective and objective) were also done. Conclusion: The current case study verifies the importance of audiological assessment for divers and importance of safety measures to be taken.
