Experts theorize that there may be several reasons for the finding, such as fewer very noisy jobs and better ear protection at worksites, immunizations and antibiotics that prevented certain diseases, and maybe even a decline in smoking.</p> <p>Experts praised the work, but agreed that scientists now must see if the pattern holds up outside of its largely white participants. They also said the result doesn’t mean it’s safe to blast loud music into your ears from an iPod for hours on end.</p> <p>Cruickshanks, colleague Weihai Zhan and others reported their work recently in the American Journal of Epidemiology.</p> <p>They analyzed the results of hearing tests given to about 5,300 people who were at least 45 years old and born between 1902 and 1962. The tests were done between 1993 and 2008, and many participants were tested at five-year intervals. Participants were residents of Beaver Dam, Wis., and their sons and daughters, who lived in a variety of places.</p> <p>The researchers noted how many tests showed at least mild hearing loss. Then they looked to see if the rate of impairment at given ages was affected by when the person was born.</p> <p>For example, take the results for men in their early 60s. The impairment rate was 58 percent for men born between 1930 and 1934. For men born just five years later, the rate was about 50 percent. And for men born between 1945 and 1949, the oldest baby boomers, the rate was only about 36 percent.</p> <p>Overall, for a given age group, men showed on average a 13 percent drop in the risk of impairment for every five-year increase in the date of their birth. For women, the decrease was about 6 percent.</p> <p>The researchers are now trying to uncover reasons for the decline. Cruickshanks said the explanation will probably be complex and hard to pin down because the pattern has been going on for decades.</p> <p>But factors could include fewer people with long-term exposure to very loud noise at work, and a decline in smoking, a habit some studies link to ear damage, she said. Changes in health care, including immunizations and use of antibiotics, may play some role too, she said.</p> <p>Now the question is whether the decline will continue with today’s young people, who often play loud music in their earbuds for hours at a time, day after day,  said Elizabeth Helzner, an epidemiologist who studies age-related hearing loss at the State University of New York Downstate Medical Center in Brooklyn.</p> <p>That chronic exposure may prove more hazardous than the briefer bouts baby boomers had, she added.</p>
