Get the Facts

Hearing loss affects 1/4 of adults in their 60s and nearly 2/3 of Americans over 70. All older adults deserve access to the tolls they need for healthy aging, but there are gaps in who gets hearing care. Less than 20% of adults with hearing loss use a hearing aid and that rate is even lower among low-income adults.
