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: Evaluation of Hearing Protection Device Effectiveness for Musicians

Sign up or log in to save this to your schedule, view media, leave feedback and see who's attending!

Feedback form is now closed.
Hearing protection devices (HPD) may offer protection to musicians, including some designed to provide uniform attenuation across frequencies. Even though these are available, studies find that musicians, especially students and instructors, do not wear them. Additionally, there is evidence indicating that many users do not achieve good fit and adequate sound reduction with HPD, which has led to recommendations for fit-testing in the workplace. Understanding the effectiveness of HPD in combination with musicians’ opinions about wearing them, we can make better recommendations for which types may be the most effective options for reducing excessive sound exposures. Twenty-four musicians were recruited and provided with three HPD: formable foam, non-custom uniform attenuation earplugs (UAE), and custom UAE. Audiometric testing was used to obtain personal attenuation levels at nine frequencies (125-8000 Hz) for each HPD which were compared to manufacturer ratings. The coefficient of variation of attenuation across frequencies was used to determine uniformity of attenuation. Participants completed surveys over six months regarding HPD use, and perceptions regarding positive and negatives aspects of wearing HPD. Survey questions were based on primary constructs of the Health Belief Model which is used to help predict whether people will engage in a specific health behavior.

Learning Objectives:
As a result of this Continuing Education Activity, readers will be able to:
1) Assess the importance of fit-testing when recommending HPD for workers.
2) Identify musicians' frequently reported benefits and barriers to wearing Hearing Protection.
3) Identify factors influencing HPD effectiveness for musicians.
