Singing does not produce substantially more respiratory particles than speaking at a similar volume, a study suggests. But it all depends on how loud a person is, according to the initial findings which are yet to be peer reviewed. The project, called Perform, looked at the amount of aerosols and droplets generated by performers.
Whether the virus is airborne isn’t simply a scientific question. If it is, it could mean that in places where the virus has not been properly contained (e.g., the US), the economy needs to be reopened more slowly, under tighter regulations that reinforce current health practices as well as introducing improved ones.

They made an experiment by releasing droplets in a room to see how it spreads. They found that people in front of the room are more susceptible and at higher risk in a properly ventilated room. In a poorly ventilated room the entire room is at risk.
Research already shows that germicidal UV can effectively inactivate airborne microbes that transmit measles, tuberculosis and SARS-CoV-1, a close relative of the novel coronavirus. Now, with concern mounting that the coronavirus that causes COVID-19 may be easily transmitted through microscopic floating particles known as aerosols, some researchers and physicians hope the technology can be recruited yet again to help disinfect high-risk indoor settings.
Governments are starting to change policies amid concerns that tiny droplets can carry SARS-CoV-2. And after months of denying the importance of this, the World Health Organization is reconsidering its stance.
Air conditioning systems partially filter coronavirus-containing viral particles, alter airflow patterns, and often, recirculate indoor air — all shifts that can influence Covid-19 transmission. A.C. also increases ventilation within a stagnant room or building, which can disperse coronavirus-containing viral droplets, and lower the chance of infection.
In January, at a restaurant in Guangzhou, China, one diner infected with the novel coronavirus but not yet feeling sick appeared to have spread the disease to nine other people. One of the restaurant’s air-conditioners apparently blew the virus particles around the dining room.
It’s not common to contract Covid-19 from a contaminated surface, scientists say. And fleeting encounters with people outdoors are unlikely to spread the coronavirus. Instead, the major culprit is close-up, person-to-person interactions for extended periods. Crowded events, poorly ventilated areas and places where people are talking loudly—or singing, in one famous case—maximize the risk.
As the weather heats up and the country opens up, scientists are trying to figure out how much effect air-conditioned air will have in spreading—or curtailing—the virus. There are multiple factors to consider, such as how AC could enable the circulation of viral particles in the air and increase the speed and distance they travel.
