Summary
Global hearing-loss estimates and definitions, including the strong relationship between age and disabling hearing loss.
Key findings
- WHO estimates that over 5% of the world population, or 430 million people, require rehabilitation for disabling hearing loss.
- Defines disabling hearing loss as greater than 35 dB in the better hearing ear; over 25% of people older than 60 are affected.
- Distinguishes hearing loss generally, relative to thresholds of 20 dB or better in both ears, from the narrower disabling-hearing-loss category.
- Lists hearing aids, implants and hearing assistive technology among rehabilitation options, alongside communication training and services.
Limits
A global fact sheet synthesising estimates, without a survey sample size or detailed estimation method on this page. It does not measure venue attendance, benefit from a particular venue system or receiver demand. The disabling-loss threshold omits milder and some unilateral losses.
