Diagnostic OAEs: Patients, Protocols and Analysis

After this webinar, you will be able to:

1) Identify the appropriate settings to create diagnostic DPOAE test protocols
2) Analyze and categorize diagnostic DPOAE test results into one of three categories
3) List the patient groups that would benefit from diagnostic OAE testing
