2023 Presidential Symposium

Presidential Symposium: "Auditory Processing, Pathology and Remediation"

President and Chair: Dr. Elizabeth Olson


This symposium is meant to convey the basic wonder of the ear and of how the ear and brain together provide our sense of hearing. Understanding the operation of the healthy ear and auditory brain is key to understanding how sound sensing can fail.

The session begins with a talk on the historical development of ideas about cochlear sensitivity by physicist Christopher Shera. Karl Grosh, an expert in the dynamic processing of the cochlea, will then review cochlear mechanics. Laurel Carney will discuss how cochlear dynamics shape neural
responses to sound, including speech. Raymond Goldsworthy will discuss how the history of cochlear implants has led to the modern device. Richard Einhorn, a composer with hearing loss, will discuss his experience with hearing loss, and share his knowledge of modern hearing aids and personal sound amplification systems. Finally, Debara Tucci will describe the global impact of hearing loss and efforts to improve accessibility.

Hearing is fundamental to communication. The impact of hearing loss, and therefore the impact of hearing remediation, is profound. This symposium is a whirlwind tour of that story -- from the history, through the basics, to what can and should and be done to address hearing health.
