Through Purdue’s Accessible Precision Audiology Research Center, Heinz and his team are refining hearing assessments that can identify the underlying causes of sensorineural hearing loss. Their work incorporates cross-species studies, artificial intelligence and open source technology to improve clinical diagnoses and expand access to affordable hearing tests. In collaboration with Creare LLC, the team is developing a low cost, mobile hearing assessment system built on the Tympan open-source hearing platform. By combining this system with a tablet and noise canceling headphones, researchers can bring accurate hearing tests to underserved populations, including rural communities where hearing care is often inaccessible.

The Weldon School of Biomedical Engineering plays a crucial role in this research by integrating engineering principles into auditory neuroscience. Through advanced signal processing, machine learning and computational modeling, Purdue engineers are helping to uncover the complex mechanisms behind hearing loss. Their work supports the development of personalized treatments and enhances the design of hearing aids and other assistive technologies.

Heinz and his team are working toward a future where hearing loss is not just detected but understood at a fundamental level. Their approach could change the way clinical trials are conducted, enabling pharmaceutical companies to develop targeted treatments based on precise diagnoses. With a commitment to accessibility, innovation and interdisciplinary collaboration, Purdue’s Weldon School of Biomedical Engineering is helping to redefine the science of hearing.
