I was confused by Con's response to the question about whether there is higher risk for 10 people to get together and sing, compared to having 10 people over for dinner, for example. Also didn't feel like he answered the question about whether the length of a rehearsal would affect the risk of getting infected?
Depending on your vocal production method, there might be very little breath actually expended from your mouth. For example, a low larynx/pharyngeal vocal placement lets out almost no breath - if you place a mirror in front of your mouth you will see no spit or condensation appearing. Even some very loud opera singers don't let out much air particles. Additionally, humming pushes air through the nose, so that mightn't actually mitigate aerosol generation.
"... speech can release dramatically larger numbers of particles compared to coughing. Early work by Papineni and Rosenthal and Loudon and Roberts reported that speaking (as exemplified by counting aloud) releases about 2-10 times as many total particles as a single cough. Similarly, Loudon and Roberts investigated the role of singing in the spread of tuberculosis and showed that the percentage of airborne droplet nuclei generated by singing is 6 times more than that emitted during normal talking and approximately equivalent to that released by coughing." www.ncbi.nlm.nih.gov/pmc/articles/PMC6382806/?fbclid=IwAR2ljBqf4J0jCD0X1F1tDGCjafojZECA40TH-rlYxddKFDQ7vOLelVbyONA
Yes -Is`nt it a misnomer to attribute any bell -like end to a wood wind or brass instrument to having a "flow of air" coming out ? I proved this with my clarinet and a candle - Then with a mask over the bell end - No difference with or without -The air pressure energy is used up at the mouthpiece end to vibrate the reed and embochure . Hence the flute does`nt have a bell end.
Surely the way forward -with your Antipodes climate- unlike that of this -in the UK is to sing -Distanced - ie to to safe and sing Alfresco ? What is golf but a natural game of distanced players -{Im alone in the rough mainly anyway!]- Lots of space- Why not think "Out side of the Concert Hall Box" ?-A new opportunity ?
Could you provide a seperate link to the video of the droplets?
Very, very interesting. Thank you !
Thank you for this up to date information

I too would appreciate a link to the video of the droplets and thank you to the students and supervisors for that very important work
Yes, I too would like a link to that video.
Or what of a flashmob Al Fresco Choir ?-Practive on zoom 1st?
If choirs hummed -Would that reduce transmission of droplets aerosol?
yes, but that's not singing. and there are no words

Fricative consonants are made with the lips. A singer can emphasise them for expression purposes with any larynx height.

And the audience wore them too?

Thankyou, from another worried singing leader. :-/
What if all singers wore masks ?
Pour moi qui ne parle pas anglais. Ce n'est pas intéressant. J'aime quand la chorale chante.
