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.

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

Poster 4: Influence of Earplugs on the Loudness and Dynamic Range of Music played by Caucasian and Filipino musicians

Louder music may be equated with more enjoyment in some cultures leading to cultural differences in the loudness of music. In addition, use of earplugs may drive some musicians to play the music louder or play the softer pieces within the music louder leading to a reduction in the dynamic range (DR) or quality of music. The specific characteristics of earplugs (e.g. NRR) may further determine the extent of the effect of earplugs. In this study, 15 musicians of Caucasian origin and 21 of Filipino origin played music in five different conditions: Trial one of conventional and musicians’ earplugs, no earplug, and trial two of conventional and musicians’ earplugs. Maximum, minimum, average (LAVG) and peak levels were recorded using a dosimeter and the DR was derived. A Mixed ANOVA revealed main effects of culture and significant interactions involving cultural origin, the plugs versus no earplug conditions, type of earplugs, and trial number. Results suggest that use of earplugs may vary the overall loudness of music and the DR in some musicians. (This project was funded by the 2015 – 2016 Wirt C. and Mae S. Belcher Graduate Education Award in the College of Education & Human Services at West Virginia University).
