Wideband Acoustic Immittance (WAI): An Introduction

In this webinar, Navid Shahnaz, Ph.D., will introduce you to wideband acoustic immittance (WAI), also known as wideband tympanometry (WBT), covering the following:

1. Explain WAI and its similarities and differences to conventional tympanometry

2. Analyze WAI patterns in normal and different middle ear pathologies

3. Differentiate WAI patterns between different age groups and different middle ear pathologies

4. Define absorbance, reflectance, and transmittance

5. Compare WAI to tympanometric outcomes in normal and different middle ear pathologies

6. Understand the pros and cons of WAI in assessment of middle ear function

7. Identify the limitation of middle ear analysis techniques and identify areas for future research direction
