Frank R. Lin, M.D., Ph.D. is the Director of the Cochlear Center for Hearing and Public Health and a Professor of Otolaryngology, Medicine, Mental Health, and Epidemiology at the Johns Hopkins University School of Medicine and Bloomberg School of Public Health. Dr. Lin completed his undergraduate degree in biochemistry at Brown University and his medical education, residency in ctolaryngology, and Ph.D. at Johns Hopkins. He completed further otologic fellowship training in Switzerland. Dr. Lin joined the faculty at Johns Hopkins in 2010 and is a practicing otologist with expertise in the medical and surgical management of hearing loss. His epidemiologic research established the impact of hearing loss on the risk of cognitive decline, dementia, and brain aging in older adults and served as the basis of the 2017 Lancet Commission on dementia conclusion that hearing loss was the single largest potentially modifiable risk factor for dementia. He now currently leads the ACHIEVE study which is a $20M NIH-funded randomized trial investigating if treating hearing loss can reduce the risk of cognitive decline in older adults. As the founder and inaugural director of the Cochlear Center for Hearing and Public Health, Dr. Lin leads a first-in-kind research center resulting from an academic-industry collaboration that is dedicated to training a generation of clinicians and researchers to understand and address the impact of hearing loss on older adults and public health.

Dr. Lin has worked extensively with the National Academies of Sciences, Engineering, and Medicine (NASEM) to address the need for more accessible and affordable hearing care for adults in the United States. From 2014-2016, Dr. Lin served on sequential NASEM committees investigating this issue and concurrently advised the White House President’s Council of Advisors on Science and Technology (PCAST) on their report. Recommendations from these groups led to the subsequent introduction and bipartisan passage of the Over-the-Counter Hearing Aid Act of 2017 which Dr. Lin testified on before Congress. This law overturns 40 years of established regulatory precedent in the U.S. and reflects the direct result of Dr. Lin’s prior research and broader policy work on hearing loss and public health. Dr. Lin currently serves as a member of the Board on Health Sciences Policy at the National Academies.

Should Hearing Aids Be Sold Over-the-Counter?

Wall Street journal  online


At the time, there was little awareness of the impact of hearing loss on health outcomes and the few available hearing aids were not very good or expensive, said Frank Lin, an associate professor of otolaryngology-head & neck surgery at Johns Hopkins University who researches the link between hearing loss and the increased risk of dementia.

Is It Time For Hearing Aids To Be Sold Over The Counter?

NPR  online


The market for over-the-counter hearing aids could be huge. More than 35 million Americans have some degree of hearing loss. And for older Americans, not dealing with the problem can have a big impact on age-related cognitive decline, says Dr. Frank Lin, associate professor of otolaryngology at Johns Hopkins University School of Medicine. Lin has done studies looking at the link between hearing loss and cognitive decline.

A Push for Less Expensive Hearing Aids

New York Times  online


How can aging ears affect so many other aspects of our health? Dr. Frank Lin, an otolaryngologist and epidemiologist at Johns Hopkins University who has led many of these research efforts, points to several possible causes. With diminished hearing, “your brain is constantly having to work harder to process garbled sounds” — a concept called cognitive load — and may have less capacity for other mental tasks.

Hearing Loss

Medical and surgical management of hearing loss in adults and other otologic conditions

Clinical expertise is in the medical and surgical management of hearing loss in adults and other otologic conditions. In particular, I am an expert in how hearing loss impacts the cognitive functioning of older adults, treatment strategies for mitigating the effects of hearing loss on cognitive decline and dementia, and surgical approaches (e.g., cochlear implantation) toward treating hearing loss.
