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 • Timestamps: • 0:00 Introduction • 0:56 Frequency range for middle ear testing • 2:44 Tympanometry in infants • 3:20 Roots of wideband tympanometry • 5:28 Advantages of wideband acoustic immittance • 6:20 Properties of the stimulus • 7:01 Energy reflectance • 8:41 Absorbance • 9:34 Terminology • 11:02 Instrumentation and software • 24:58 Effect of probe insertion depth • 28:54 Wideband acoustic immittance in newborns • 43:02 Wideband acoustic immittance in children • 50:59 Wideband acoustic immittance in adults • 59:53 Case studies • 1:04:50 Wrap up and Q A
