Singing is an enjoyable, stress-releasing activity that most people enjoy. But the medical experts have warned that singing can cause coronavirus spread just like how talking with random people can spread it. It applies to both professional signers, singing in public or performing in a concert, and those who sing or hum around for fun.
These results are based on a study that is currently not peer-reviewed.
Although there is no link to singing to spread coronavirus directly. But the researchers have found that singing also delivers some respiratory particles like those which are delivered during talking. That’s why the risk of coronavirus still remains, even if you aren’t talking but singing. The severity of this spread is based on how loud a person is singing.
These warnings came up after a team of researcher from the University of Bristol worked on a project named “Perform” which was to analyze the number of aerosols and other particles in the air which are generated through performers or artists.
This report may be limited to indoor singing or indoor performances which are approved in some areas for the world. As the world is resuming back to routine life after spending months in lockdown, suspending all activities and businesses, the re-opening of clubs and singing performances are just a part of it.
Although the restrictions on all these entertainment activities are eased along with recommended measures followed to control the spread, it doesn’t look like that they will help. During the indoor performances, which are advised to be opened under social distancing protocols, the tiny aerosols particles expelled from the body suspend in the air and reach to any nearest surface.
The latest evidence on coronavirus suggests viral transmission is possible through aerosol particles which is why the risk of spreading coronavirus via singing is a big threat.
Nearly 25 performers from different ages, gender, ethnicity, and performances were a part of this study. Each one of them was asked to complete different types of practices including professional singing and casual singing i.e. singing Happy Birthday song. Their singing was analyses on a different volume, sound, and pitches level inside an operating theatre with no aerosol contamination.
The researchers were able to investigate aerosols release on different types of sound from singing. They concluded that singing in general initiates a large number of aerosols to release. They suspect that this risk could be even higher than ‘normal talking’ as singing is performed on a much higher volume and pitch which may generate aerosols 30 times higher than talking alone. The effect of playing an instrument was also checked.
Jonathan Reid, from the University of Bristol, is one of the authors of this study. According to him, ventilation of a room or theatre may impact the buildup of aerosols at large. When this venue is bigger there are chances of aerosols concentration.
He also says that this study highlights an important side of coronavirus transmission which is still out of control. Only by opting for safety measures, people can avoid getting this virus, which is airborne and highly contagious.
