According to a study done by John Hopkins Medical Institution, nearly 2/3rds of Americans age 70 or older have hearing loss. Interestingly enough, people of ethnicity who tend to have darker skin seem to have some kind of measure of protection against this kind of age-related hearing loss.
Older adults having hearing loss is a major issue as baby boomers reach retirement age and depend on assistive technology to overcome hearing limitations. If this study is accurate, we could be facing a rising tide of people living longer and longer and having to face hearing loss as a natural side effect of getting older. I would gather that there’ll be a heightened need for services like captioning and looping as this continues.
