Researchers analyzed data from 27,656 Americans between 23 and 43 years old in the ADD Health study. They found that participants reporting to have poor or worse hearing had significantly lower educational attainment, a lower probability of being in paid work, and earned less than their peers. These negative impacts of hearing loss were especially pronounced for Black and Hispanic Americans. Suffering from tinnitus was not found to have any effect on these outcomes. The authors propose better access to hearing care, early screening, and workplace support, as well as reducing stigma, to level the playing field for people with hearing loss.
