Music Induced Hearing Disorders 2018




Nina Kraus, is Hugh Knowles Professor of Communication Sciences, Neurobiology, and Otolaryngology at Northwestern University.  She is a scientist, inventor, and amateur musician who uses hearing as a window into brain health. She began her career measuring responses from single auditory neurons and was one of the first to show that the adult nervous system has the potential for reorganization following learning; these insights in basic biology galvanized her to investigate auditory learning in humans.

Through a series of innovative studies involving thousands of research participants from birth to age 90, her research has found that our lives in sound, for better (musicians, bilinguals) or worse (concussion, aging, hearing loss, language disorders), shape auditory processing. She continues to conduct parallel experiments in animal models to elucidate the mechanisms underlying these phenomena.

Never having accepted a lack of technology as a roadblock to scientific discovery, Kraus has invented new ways to measure the biology of sound processing in humans that provide unprecedented precision and granularity in indexing brain function. With her technological innovations she is now pushing science beyond the traditional laboratory by conducting studies in schools, community centers, and clinics.

Using the principles of neuroscience to improve human communication, she advocates for best practices in education, health, and social policy.



Sharon G. Kujawa, Ph.D. is an Associate Professor of Otolaryngology, Harvard Medical School. She is the Director of Audiology Research and a Senior Scientist in the Eaton-Peabody Laboratories, Massachusetts Eye and Ear Infirmary, Boston, MA. She also serves on the faculty of the Program in Speech and Hearing Biosciences and Technology at Harvard University. Dr. Kujawa is a clinician and an auditory neuroscientist whose research seeks to clarify mechanisms and consequences of common causes of acquired sensorineural hearing loss and to translate that knowledge into improved diagnosis and treatments that benefit people. A major focus of current work is understanding how sound overexposure and aging cause loss of cochlear hair cell – nerve fiber connections/communications (synapses), determining the functional consequences of that loss, and clarifying how the degeneration can be manipulated pharmacologically to reveal mechanisms and provide treatments. Her research is supported by the National Institutes of Health-National Institute on Deafness and Other Communication Disorders, the Department of Defense and the Office of Naval Research.

He is the author of over 200 articles and 8 books including Musicians and the Prevention of Hearing Loss, and recently, an e-book Music To Your Ears available from He writes a monthly column in Hearing Review called Back to Basics and a weekly blog at Dr. Chasin has been the recipient of many awards over the years including the 2012 Queen Elizabeth II Silver Jubilee Award for service to Canada. He has developed a new TTS app called Temporary Hearing Loss Test app. This is a tool to help prevent hearing loss.


Dr. Cory Portnuff is a clinical audiologist at the University of Colorado Hospital and an Assistant Clinical Professor at the University of Colorado Denver School of Medicine.  In the clinic, he works with patients of all ages, with a focus on audiologic rehabilitation, treatment for tinnitus and services for musicians. Dr. Portnuff is board certified in audiology with a specialty certification in pediatric audiology.  His research focuses on hearing loss prevention, including noise-induced hearing loss in children and hearing protection for musicians. In his free time, he enjoys hiking, camping, and long walks on Colorado beaches.




Jon is a senior research scientist and program manager at GN Hearing, where he designs psychoacoustic experiments to push the limits of tiny audio systems (hearing aids). His research involves sensory analysis, experimental design, psychoacoustic & neural modeling, electroacoustics, and signal processing.


Dr. Marc Fagelson is Professor of Audiology at East Tennessee State University. He received a BA in English and MS in Audiology from Columbia University, and his PhD in Hearing Science from the University of Texas – Austin. His academic teaching includes courses covering hearing science, audiologic evaluation, pathologies of the auditory system, and tinnitus management. Fagelson co-edited with Dr. David Baguley, two texts published by Plural that center on tinnitus and disorders of sound tolerance. He has more than 35 publications and has made more than 100 conference and workshop presentations. In 2001, he opened the James H. Quillen VAMC Tinnitus Clinic that now enrolls more than 1000 patients. The clinic offers extensive and collaborative counseling for patients, as well as a variety of sound therapy strategies designed to foster a patient’s ability to manage their tinnitus experience and sound tolerance issues. A substantial proportion of the veterans in that clinic experience tinnitus that is complicated by the influence of co-occurring psychological conditions, and in particular posttraumatic stress disorder. This challenging and underserved population is the focus of Dr. Fagelson’s research. His most prized possession is a 1960 Fender Precision.


Dr. Sridhar Krishnamurti is Professor and Program coordinator of Audiology in the Department of Communication Disorders at Auburn University. Sridhar was a recipient of the College of Liberal Arts Engaged Scholar Award at Auburn University (2014-2017). He currently serves on the Research grants panel of the DOD and is funded by Army Research Office ORISE program. Sridhar’s previous awards include the 1999 New Investigator Research Award from the American Academy of Audiology, the 2011 Auburn University Alumni Undergraduate Teaching Excellence, and the 2012 Auburn University Faculty Research award. He has served as the past-continuing education administrator for ASHA’s Audiology Special Interest Divisions 6-9 and is a Fellow of the American Academy of Audiology.
