Criteria for Determining Hearing Disability: A Narrative Review of Global Perspective

This report reviews current literature on audiometric thresholds used globally to determine hearing disability, highlighting challenging cases worldwide. Databases PubMed, Embase, and Web of Science were searched for articles on hearing disability criteria published from 2010-present in English. Overall, developed countries employ a pure-tone average (PTA) of ≥ 40 dB as disability criteria, while developing countries use ≥ 41 dB PTA. The World Health Organization uses ≥ 41 dB disabling hearing loss in better ear. Studies show widespread use of a single frequency threshold in some countries can exclude milder losses. Individualized appr oaches accounting for communication function, rather than fixed PTA cut-offs alone, enable more accurate disability determination. Further research on optimal, equitable criteria accounting for resource availability is needed. Standardized guidelines balancing sensitivity and specificity in disabili ty determination worldwide would enable improved rehabilitation access and outcomes.
