George S. Osborne College of Audiology

Australia 2014 Workshops

Electrophysiology in Audiology: June 19-22, 2014

Course Summary

This advanced workshop will cover various theoretical and practical topics related to data acquisition and analysis of Otoacoustic Emissions (OAE), discussion of the afferent and efferent pathways, frequency-specific Auditory Brainstem Response (ABR), tone-burst ABR, Auditory Steady State Response (ASSR), Middle Latency Responses (MLR), Late Potentials including N1-P2, P300, Mismatch Negativity (MMN), and Electrocochleography (EcochG). There will be particular emphasis on hands-on training and participants will be encouraged to bring case studies for review and class discussion

Learning Objectives

  1. Describe the physiology and micro-mechanism of cochlear function
  2. Identify causes of cochlear dysfunction
  3. Identify potential uses and limitations of otoacoustic emission testing
  4. Describe generators of the auditory brainstem response (ABR)
  5. Describe the relation between tone burst frequency and latency of the auditory brainstem response (ABR) wave V component
  6. Define what is meant by “chirp” stimulus in auditory brainstem response (ABR) measurement
  7. Describe generators of the auditory middle latency response (AMLR)
  8. Describe stimuli used to evoke the auditory late response (ALR)
  9. State the reason why ECochG is useful in diagnosis of auditory neuropathy spectrum disorder
