THE SPECIAL RELATIONSHIP BETWEEN ACOUSTIC, VIBRATION AND HUMAN RESPIRATION

Abstract

Wearing surgical face masks is among the measures taken to mitigate the transmission of the coronavirus disease (COVID-19) and reduce deaths. Respiratory aerosols are the main route of virus transmission and the widespread use of face masks decreases the ability to spread SARS-CoV-2 by minimizing the inhalation of respiratory droplets from asymptomatic infected individuals or from people who have not yet shown symptoms while preventing the elimination of respiratory particles by the contaminated persons. With help of the laser photoacoustic spectroscopy technique, in this preliminary research, the ethylene as a byproduct of oxidative stress from the human respiration were measured before and after wearing surgical face masks. Our study demonstrates a non-significant increase in the ethylene concentrations among volunteers while donning surgical mask for one hour.
