NCRAR Monthly Seminar Series - CEU Details

The current month's seminar info and CEU documents are below (see highlighted section when you scroll to the bottom of the page).

Time: 12-1pm (Pacific)

Location: VA Portland Health Care System, NCRAR (Virtual)

 Eric Bielefeld, Au.D., Ph.D.

Title: Expanding our View of Ototoxicity as we Expand our Definition of Hearing Loss

Abstract: Pre-clinical research has helped to inform an expanding definition of hearing loss beyond what can be gleaned solely from the clinical audiogram. As that definition of hearing loss expands, so does the need to investigate different drug compounds for potential ototoxicity and techniques to prevent it. Further, we are challenged to evaluate how different sources of hearing loss interact with each other to induce threshold shifts and/or impairments of supra-threshold complex sound coding.

Learner Outcomes: Upon completion of this session, participants will be able to:

• Describe the conventional and expanded clinical perspectives on hearing loss.
• Identify new classes of compounds that have the potential to be ototoxic and for which ongoing research is needed.
• Describe how different causes of hearing loss can interact with each other in additive, synergistic, or antagonistic ways.

Note: Eric Bielefeld is a licensed and certified audiologist, and professor in the Department of Speech and Hearing Science at The Ohio State University, has relevant financial relationships to disclose as a recipient of grants from the American Speech, Language and Hearing Foundation, and The Ohio State University Addiction Initiative, and no non-relevant financial relationships to disclose.
