NHCA 2021 Virtual Conference has ended
Welcome to the 2021 NHCA Virtual Conference Schedule, below you will find the schedule listed with 3 types of education sessions, Live Platform, Pre-recorded Platform and E-Poster Sessions. They will all be delivered a little differently so please take a little time to read the descriptions and understand how the conference will be laid out.

  • Live Platforms: NHCA is offering 7 live sessions with interactive Q&A and chat features over the two days of the live conference. If you are not able to watch these sessions live they will be recorded and playback will be available until March 19, 2021
  • ON DEMAND Pre-Recorded Platforms: There will be 28 pre-recorded sessions that will be released on the first day of the conference, these will be available to watch at your leisure and will be available until March 19, 2021. PLEASE NOTE: They are available longer than the 1-5 pm time on the schedule but we are not able to program them in like that!
  • ON DEMAND E-Poster Sessions: There will be 8 E-Poster sessions available to watch, each session is 15 minutes long and worth a quarter of a credit, in order to receive a full hour you will need to watch 4 poster sessions all the way through and complete and evaluation. These will be available as pre-recordings and will be available from the start of the conference until March 19, 2021
This means you have the opportunity for up to 19.0 CE credits at this years conference! (See ASHA AND AAA Brand Blocks below)

Airborne sound reaches the cochlea via the middle ear, which acts to minimize the impedance mismatch between the air and the cochlear fluids. Measurements of the amounts of energy absorbed as a function of frequency (i.e., wideband energy immittance) have recently been integrated in clinical equipment. Small- and medium-scale studies with convenience samples have demonstrated that these measures are reliable and differ systematically across people. However, no reports of such differences have ben made at the level of the U.S. population. In this study, we describe wideband immittance patterns observed in the U.S. National Health and Nutrition Examination Survey (NHANES) as a function of age, gender, race/ethnicity, and other factors. The potential role of between-subject differences in middle ear energy transmission as a component of susceptibility to noise-induced hearing loss will be discussed.

As a result of this Continuing Education Activity, readers will be able to:
1) Identify applications of wideband immittance and tympanometry in susceptibility to Noise induced Hearing Loss.
2) Describe the typical wideband absorbance spectrum related to middle ear transmission.
3) Describe the range of intersubject differences in wideband absorbance spectra in the U.S. population
