Exposing Hidden Hearing Loss (Live Webinar)

Noise exposure and aging are common causes of acquired sensorineural hearing loss, marked by damaged hair cells and evident in threshold audiograms. Recent studies have shown that well before overt hearing loss is apparent, a more insidious process frequently occurs, one that doesn’t kill hair cells, but instead permanently interrupts their communication with cochlear neurons. This cochlear synaptic loss can be dramatic, even in ears with normal threshold audiograms, where it has been called “hidden hearing loss.” This webinar will review hidden and overt effects of noise and aging on the ear and hearing, focusing on documented synaptopathic and neurodegenerative outcomes and predicted functional consequences, including speech-in noise difficulties, tinnitus, and hyperacusis.
You will be able to:
- identify strengths and limitations of threshold tests in characterizing age-related and noise-induced functional compromise
- describe common consequences of TTS-producing noise exposure on the ear and hearing
- define cochlear synaptopathy and hidden hearing loss
Group Registration Note: A group registration entitles you to view this program one time, on one connection. Any number of people may watch and earn ASHA CEUs/professional development hours. The person who will act as group leader for the broadcast should register on behalf of the group. The group leader will be able to play the webinar and pass out a link to group members so they can access handouts and the learning assessment to earn CE credit. The group leader needs to have, or create, a login to the ASHA Web site.
