Recently, researchers have discovered an association between the prevalence of hearing impairment and year of birth. Specifically, it has been discovered that the percentage of people with hearing impairment is declining with each generation. Researchers expect this trend to continue, and more people are expected to maintain good hearing into their later years.
It has been theorized that this positive trend may be attributed to a transition from blue collar to white collar careers, and the creation of occupational noise regulations.
