Talking Heads: 3D Head Scanning to Assess the Dynamic Fit of Face Masks

Abstract

In this study, we looked at the static and dynamic fit of three commercial face masks by scanning participants in both stationary mouth positions (open and closed) and after completing a standard talking exercise. The findings included methodology development and showed visible differences between the N95 respirator, surgical face mask, and cloth face mask. The main mode of shifting with talking was the masks sliding down the bridge of the nose, along with other observations such as gaps between mask perimeter and face, and extended pleats not recovering. This study serves as a demonstration of the feasibility of using a 3D Head Scanner as a tool to analyze the static and dynamic fit of prospective face mask designs.
