Housed in Lyles-Porter Hall, the Audiology Research Diagnostics Core (ARDC) at Purdue has been created as a collaborative effort to reduce the entry barrier to auditory neuroscience for new and cross-disciplinary investigators. In addition to the listed services our facility offers, we are developing a solution for harmonization and analysis of human and animal subject data across multiple laboratories, as well as large-scale web-based data collection, to investigate trends and comprehensively study hearing pathologies.

Our efforts have led to the development of open-source software and a framework to harness clinically-applicable audiological measurements typically used for hearing screenings in research studies in a homogenous manner. Using these data, we are efficiently answering questions in hearing science and audiology that require large datasets-- which will lead to improvements in clinical outcomes, assistive technology, and quality of life.

Using large-scale data analysis techniques, we are also investigating the ability of current and novel diagnostics to predict hearing loss.

All measurements are currently collected within a noise-isolated soundbooth by a trained operator. Currently, we have 6 operators consisting of an Audiologist, AuD students, and graduate students within SLHS and BME.
