Experimental and theoretical study of the influence of mouth mask on the upper airway fluid and aero-acoustic mechanisms: respiration and human speech sound production

The current covid-19 pandemic introduces a mouth mask in daily life (see Fig. 1). In countries such as France were the population is un-accustomed to wearing a mouth mask, it appears that explicit obligation is needed as it might provoke discomfort. In this physical study, it is aimed to investigate how a mouth mask affects the fluid flow in the upper airway and associated flow induced phenomena such as the fluid-structure interaction leading to human voice production. Objective and quantitative evidence to the influence of a mouth mask on the upper airway flow might in term contribute to understanding of the respiratory function, to the mentioned discomfort and even consider when the discomfort becomes problematic. The internship relies on an experimental and modeling aspect as briefly outlined below...
