Mastering Distortion Product Otoacoustic Emissions (DPOAEs)

Welcome to this Interacoustics Academy Learning Path on DPOAEs. This course is designed to equip you with the theoretical and practical understanding of how to perform DPOAEs. This course will explore the clinical utility of DPOAEs as a diagnostic tool, how to perform a measurement on a patient, the settings and parameter options available to devise a protocol for testing, and the important components of a recorded measurement to consider to make the interpretation of a result.

Learning objectives

• Describe the clinical utility of OAEs in different patient populations.
• List the different parameters that can be selected for stopping criteria within a DPOAE measurement.
• Describe why normative data values are important for interpreting DPOAE results.

Course presenters

Amanda Goodhew

Amanda holds a Master's degree in Audiology from the University of Southampton. She has extensive experience holding senior audiologist positions in numerous NHS hospitals and clinics, where her primary focus has been pediatric audiology. Her specific areas of interest include electrophysiology (in particular ABR, ASSR and cortical testing), neonatal diagnostics and amplification and the assessment and rehabilitation of patients with autism and complex needs. Amanda has a particular interest in pediatric behavioral assessment and has twice held the Chairperson position for the South London Visual Reinforcement Audiometry Peer Review Group. Amanda also works as an independent technical assessor for the United Kingdom Accreditation Service, undertaking quality assessment for audiological services throughout the UK, and provides guest lecturing services to universities both in the UK and abroad.

Dr. Peter Bray, Ph.D.

After obtaining a Medical Physics degree, Peter Bray worked for 5 years as a researcher in David Kemp's team at University College London. This led to a PhD in Biophysics and the design of the ILO88 TEOAE instrument. The following 25 years were spent providing R&D services at Otodynamics designing TEOAE and DPOAE instrumentation. Then, in 2014, Peter joined Interacoustics as an OAE specialist and data scientist working on the full range of OAE topics in addition to ASSR screening technology.

Dr. Lisa Hunter, Ph.D.

Lisa Hunter is the scientific director for Audiology in the Communication Sciences Research Center at Cincinnati Children’s Hospital Medical Center, and a professor of Otolaryngology and Communication Sciences and Disorders at the University of Cincinnati. Dr Hunter has more than 25 years of pediatric clinical, research, and teaching experience. A graduate and former faculty member of the University of Cincinnati and the University of Minnesota, she developed and directed the AuD program at the University of Utah. She was a visiting scientist at the Karolinska Institute in Stockholm, Sweden, and has volunteered in Kenya on audiologic missions at a school for the deaf. Dr Hunter has authored more than 90 published articles, chapters, and books in pediatric audiology and frequently lecture nationally and internationally, as well as serving on expert panels and task forces. Dr Hunter is currently conducting studies on a range of pediatric hearing loss, funded by the National Institute on Deafness and Other Communication Disorders and the Centers for Disease Control (CDC). She also serves as chair of the Accreditation Commission for Audiology Education (ACAE).
