Audiology Recorded Webinar – Exposing Hidden Hearing Loss, its Multiple Etiologies, and Clinical Presentations

Recorded Event:  Viewing available from April 1 to April 30, 2024

Presenter: Zarin Mehta, PhD, CCC-A, FAAA, A.T. Still University

Abstract:  Hidden hearing loss (HHL) is a relatively recently reported auditory neuropathy when patients present with normal/near normal audiograms but difficulty with speech intelligibility. To perceive auditory signals, it is necessary that the peripheral cochlear sensory cells, cochlear neurons, and central auditory system are all functioning normally. In animal and human studies, HHL exhibits impaired cochlear neurotransmission because of defects of inner hair cell synapses with cochlear nerve fibers (auditory synaptopathy). In humans, the impaired cochlear neurotransmission manifests as difficulty understanding speech, especially in noise. These changes are often observed as a result of noise exposure, ageing, defective myelination, and with some neurodegenerative diseases. This presentation will explore the pathophysiology of HHL as reported in the literature along and its multiple etiologies. Clinical presentation(s) and management of
HHL will be discussed and exemplified through case studies.

Learner Outcomes:
After completing this course, participants will be able to:

  • Identify the multiple etiologies of hidden hearing loss
  • Describe the clinical presentation(s) of hidden hearing loss
  • Identify and describe the appropriate management of hidden hearing loss.

Information Level: Intermediate
