NIH-Funded Research Project:  Neuroplasticity and Auditory Aging

The Hearing Research Lab is participating in a multidisciplinary research project that will examine strategies to improve communication challenges for millions of senior citizens

The National Institute on Aging awarded more than $8 million to the University of Maryland to develop an innovative approach for addressing hearing loss and communication challenges that affect millions of older Americans. The five-year, multidisciplinary research project will combine expertise from the College of Behavioral and Social Sciences; the A. James Clark School of Engineering; the College of Computer, Mathematical, and Natural Sciences; and the Center for Advanced Study of Language. The project is led by Principal Investigator Dr. Sandra Gordon-Salant, Director of the UMD Hearing Research Lab.

The overarching goal of the research will be to examine processes at the neural level that cause auditory and speech perception difficulties with aging, and to determine whether the brain can be effectively “rewired” through auditory and cognitive training to overcome these hearing and speech obstacles. To achieve this aim, the UMD research team will focus on three distinct projects:

  • Project 1 will examine whether neurons in the auditory cortex of the brain can be reorganized through specific training exercises.
  • Project 2 will assess the effectiveness of focused strategies in helping people process acoustic signals, including rapid speech—a common obstacle for senior citizens.
  • Project 3 will combine cutting-edge neuroimaging techniques—such as magnetoencephalography (MEG) and pupilometry—to measure the brain’s ability to form new neural connections following auditory and behavioral training.

“There are many training programs designed to help people deal with hearing loss as they get older,” said Professor Sandra Gordon-Salant from the Department of Hearing and Speech Sciences, who will serve as the overall project’s lead investigator. “What we don’t know is how well these training programs work and if they result in a true rewiring of the brain. We’re thrilled to have compiled this dynamite team that will help provide answers to these important questions.”

According to a recent publication by the National Academies of Science, Engineering and Medicine, nearly half of all Americans 65-years-old and above struggle with age-related hearing loss. That percentage climbs to 63 percent for people older than 70. Combined with data from the U.S. Census Bureau, that means roughly 25 million older Americans are currently dealing with hearing loss—a number likely to increase to 35 million by the year 2030. The biggest communication complaint of those with age-related hearing loss is difficulty understanding speech in challenging situations, which often leads to isolation and depression.

“We think that as the population ages, they’re going to be more demanding about solutions to their problems,” Gordon-Salant said. “Hearing aids are beneficial but they can’t do it all. There is a tremendous need for effective training programs and this research has the potential to transform the nature of rehabilitative services for millions of older people with communication problems.”

We are currently seeking participants for our projects! 

Dr. Sandra Gordon-Salant and her colleagues are seeking participants for these new projects!  Specifically, we are seeking young adults with normal hearing or older adults with either normal hearing or hearing loss.  The purpose of the study is to develop an effective training program to improve speech understanding in challenging listening situations experienced by older people.  The study will involve preliminary testing, the training protocol, and post-training testing, and takes about 20 hours to complete.  To sign up for an assessment to determine if you qualify, please email our Human Subjects Research Coordinator, Ms. Carol Gorham at: or by phone at : 301-405-4236. Include your phone number and email address, and Ms. Gorham will contact you to arrange a date and time for your first visit.
