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)

ON DEMAND SESSION: Tablet-based alternatives to field attenuation evaluation systems

Feedback form is now closed.
Earplugs are a very popular form of hearing protection device (HPD), but they must be correctly sized and properly inserted to ensure that they consistently provide enough attenuation to protect from high-level noise exposures. Under ideal circumstances, it would be possible to check the personal attenuation ratings (PARs) of all noise-exposed personnel with a commercial-grade Field Attenuation Evaluation System (FAES) to verify that they are all issued suitable HPDs and that they know how to use them. However, practical considerations often preclude the use of these systems for all noise-exposed workers. In such cases, it may be necessary to consider alternative solutions that are more portable or less burdensome than traditional FAESs but still provide adequate information about the attenuation provided by HPDs. In this study, we evaluated a variety of simplified procedures run on a commercial tablet for estimating HPD attenuation and compared their results to attenuation values measured with a commercial FAES. The advantages and disadvantages of each approach will be discussed in addition to the appropriate real-world scenarios in which each method could be deployed. The potential for using the tablet-based approaches for HPD education and training will also be discussed.

Learning Objectives:
As a result of this Continuing Education Activity, readers will be able to:
1) Describe current methods of measuring personal attenuation ratings for Hearing Protection Devices.
2) Identify portable assessment tools for Hearing Protection Devices.
3) Describe one tablet-based Personal Attentuation Rating screening and assessment tool.
