Prevalence of hearing loss worldwide as of 2019, by degree of hearing loss
"All hearing loss is defined as any hearing loss above 20 dB, ranging from mild to complete in severity"
* Rates are age-adjusted. Age-standardised rate (ASR) is a summary measure of the rate that a population would have if it had a standard age structure. Standardization is necessary when comparing several populations that differ with respect to age because age has a powerful influence on hearing loss.
