According to Men’s Health, public officials are sending out an extremely clear message. They believe that individuals should wear a mask when leaving their house to prevent the spread of the novel coronavirus. For now, public officials have not made it clear regarding what sort of mask should be worn and how effective wearing a mask truly is.
The Florida Atlantic University is trying to offer a little guidance with its new research. The study performed by the Florida Atlantic University has been made public in the Physics of Fluids, an academic journal. The study takes a look at artificial sneezes and coughs created with a smoke machine over the head of a mannequin and using a special laser to identify the theoretical droplets and investigate their volume, trajectory and risk in a real-life situation.
Over the course of the study, the researchers placed several types of cloth face masks on the unlucky mannequin and noted how many droplets from the sneezes and coughs of the mannequin actually managed to get out of the cloth mask. Researchers have also attempted to find out the distance that the regular respiratory droplet travels.
The results of the study are as follows: Face masks that have been tied only loosely and bandana-style masks placed on the mannequin have caused the respiratory droplets to travel only one eight the distance that a normal, maskless droplet would travel. On the other hand, well-fitted mask made out of multiple layers of fabric and especially cone-style masks were found to work the best. With cone-style masks, droplets have only traveled for about 8 inches, while with quilted masks, the distance adds up to about 2.5 inches. Some of the less effective materials out there include a simple folded handkerchief. This basic preventive measure enables the droplets to travel for more than 3 feet.
