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)

The noise and blast hazards of many weapon systems cannot be completely abated without reducing mission effectiveness, and hearing protection strategies are ineffective when exposure is unpredictable or if sound intensity exceeds hearing protection device capabilities. “Characterization of Acute Short-term Military Population Auditory Shifts” (CHASMPAS) is a military study to characterize noise and blast exposures experienced during weapons training, monitor for acute or short-term-acquired hearing changes, and directly correlate such changes to noise and blast dose. This is done by collecting data in the field at the time of exposure, and by using advanced boothless audiology technology and noise and blast measurement techniques. Boothless technology allows rapid administration of tests for comprehensive evaluation of auditory function. The resulting dataset will be augmented with demographic and clinical data, and evaluated using multi-dimensional, big-data analysis methods. CHASMPAS aims to extensively characterize and map noise and blast conditions as they relate to various aspects of hearing function, and to evaluate dose-response effects and risk-mediating factors. This research will help elucidate the effects of injurious noise and blast and identify populations that may benefit most from future studies of pharmaceutical interventions for noise-induced hearing loss. This presentation discusses study aims, design, and preliminary results.

Learning Objectives:
As a result of this Continuing Education Activity, readers will be able to:
1) Describe the use of boothless audiology technology in assessment of threshold shifts in military service populations.
2) Describe the noise/blast measurement techniques employed in military exposures.
3) Describe preliminary findings of the auditory and noise/blast measurements data.
