UC Davis Study Finds That Loud Talkers, Regardless of Language, Spread More Airborne Germs

A study from UC Davis, published in Nature and called "Aerosol emission and superemission during human speech increase with voice loudness," finds that: "The rate of particle emission during normal human speech is positively correlated with the loudness (amplitude) of vocalization."To explain: As we all know, coughing or sneezing sends potentially virus-carrying droplets into the air. These coughed or sneezed particles are often large enough for the eye to see, about 50 nanometers or...
