Abstract/Artist Statement
Many airborne diseases, such as COVID-19 and flu, are spread through aerosol droplets emitted by the human respiratory system. Public health officials utilized a variety of disease mitigation methods throughout the recent COVID-19 pandemic that focused on reducing the spread of respiratory droplets that carry pathogens, such as wearing face masks and increasing distance between individuals. Several studies have already proven that the concentration of aerosol particles emitted through the respiratory tract increases as the loudness of speech and proximity to the particle counter increases; however, the differences in concentration based on the language the participant is speaking has yet to be studied in detail. For this study, preliminary data was collected by having the participant sit in front of a laptop and follow the instruction on the monitor. In this study the concentration of respiratory aerosol particles and physiological data such as photoplethysmogram (PPG) and electrodermal activity (EDA) are collected during normal breathing and reading the passages. Same passage is translated to Hindi and Spanish, and the subject is instructed to repeat the experiments 5 times. Based on our preliminary results, there is very little difference between the total concentration of respiratory particles emitted when speaking English and speaking Hindi or Spanish, but there is the difference in total concentration between simply breathing and speaking.
