The news: Thousands of droplets from the mouths of people who are talking loudly can stay in the air for between eight and 14 minutes before disappearing, according to a new study. The research, conducted by a team with the US National Institutes of Health and published in PNAS Wednesday, could have significant impact on our understanding of covid-19 transmission.
The findings: The researchers asked people to repeat phrases and used sensitive lasers to visualize the droplets they produced, watching them decay in a closed, stagnant air environment. On the basis of previous studies of how much viral RNA can be found in oral fluids in the average covid-19 patient, the researchers estimate that a single minute of loud speaking generates at least 1,000 virus-containing droplets. Their observations suggest these droplets stay airborne for longer than eight minutes, and sometimes as long as 14 minutes.

Thanks for sharing it. I totally agree that the example will help my research project as well. I just wonder what the differences between talk-aloud and think-aloud are. I am planning to use one of these data-gathering methods for my research, and not quite sure which one to apply into it. Could you please give me more details or suggest any paper if it is possible?
Natalia Perera is well acquainted with the difficulties of working with a loud talker. The innovative director of Syneka Marketing sits directly opposite the company's managing director who, she says, has a booming, baritone voice.
"I have also seen cases where the perpetrator feels picked on for this behaviour being raised," she says. "If an employer or colleague does not handle the situation sensitively it can cause more angst than the loud talking did to begin with."

But in some cases, when people talk to themselves in an erratic or muttering way, it could indicate a mental health disorder. This type of talking out loud can be an early sign of schizophrenia that can worsen if untreated.
The mental and social benefits of self-talk have long been debated by philosophers. Self-talk can help you make decisions more easily and motivate you to do things you may be putting off. Keeping a positive outlook and talking to yourself kindly can have great impacts on your overall mental health.
One of the main symptoms of schizophrenia is disordered thoughts. Your thoughts may feel blocked or jumbled. When you speak them out loud they may not have a logical order. When you talk to yourself you might make up new words, repeat single words or phrases with no context, or give new meanings to words.
You may have vented some frustration with a few exclamations (even expletives). You probably also talked yourself through the toughest parts, maybe even reminded yourself of your progress when you felt like giving up. In the end, you succeeded, and talking to yourself may have helped.
Taking some time to sit with these emotions can help you unpack them and separate potential worries from more realistic concerns. While you can do this in your head or on paper, saying things aloud can help ground them in reality.
Users in two different buildings are reporting their phones are beeping and flashing a message on the phone display telling them they are being too loud. Initially I thought they were talking about paging and that someone was playing jokes. But the message displays on the phone screen, the only sound is a beeping tone.
I bring this up because as I write this, I am on an airplane, using earbuds. I arrived quite early for my flight and while waiting in the terminal, a gentleman near me began talking loud enough for everyone in the area to hear. He proceeded to take call after call, with clients and co-workers, all while speaking so loud we could not help buy overhear his plans. Now, he and his colleague are seated behind me sharing every detail of their business plans. I can now tell you how they plan to have their teams address each market, what they plan to do to grow from $2.5 M to $17 M in revenue this year, what they are worried about, etc. I can tell you about the funds they are managing.
Lydia Bourouiba, an associate professor at MIT whose lab explores the effects of exhalations like coughs or sneezes, is another scientist who believes the virus can travel far further than previously appreciated. In an article for JAMA, Bourouiba wrote that "peak exhalation speeds can reach up to 33 to 100 feet per second, creating a cloud that can span approximately 23 to 27 feet," and called for revised CDC and WHO guidelines.
The authors of the newly-released NIH study on loud speech said that a damp homemade cloth mask could help to catch the amount of droplets produced when talking, adding their findings to the growing pile of evidence declaring homemade masks a necessary part of fighting off a virus.
Hoarseness (dysphonia) is when your voice sounds raspy, strained or breathy. The volume (how loud or soft you speak) may be different and so may the pitch (how high or low your voice sounds). There are many causes of hoarseness but, fortunately, most are not serious and tend to go away after a short time.
Oftentimes, we spend so much time preparing the content of our presentation that we overlook the basic aspects of presenting which include how to speak and loudly and clearly. The way you speak and project your voice can have a drastic impact on your presentation. Everything from tone and pitch to volume and pace can affect your ability to engage your audience. As you prepare for your next presentation, consider the importance of your voice and practice these tips for speaking loud and clear.
You should pay close attention to the way you speak because it can affect the way your audience perceives you. A loud, slow, and deliberate voice allows for better enunciation and clarity. It also signals confidence, intelligence, and credibility to the audience. Audiences will find your message to be more persuasive if you speak loud and clear.
Unusual speech. Children with autism spectrum disorder have good vocabularies but unusual ways of expressing themselves. They may talk in a monotone voice and do not recognize the need to control the volume of their voice, speaking loudly in libraries or movie theaters, for example.
Social isolation. Children with the condition have trouble making friends because they are awkward in social situations. They may stand too close or talk too loudly to others, who may see their behavior as odd or inappropriate.
Oversensitivity. Children with the condition may be unusually upset by loud sounds, bright lights, strong smells, or being touched. They may also be easily upset by any change in schedules or routines.
We're still not entirely sure as to what is going on, but it seems to involve a feedback loop. Once you have a few drinks, your sense of hearing is impaired. So when you speak, you mistakenly think that you are talking more softly than usual. To compensate, you (without even thinking about it) automatically start talking louder.
The relative loudness of human speech and the different decibel levels a human can speak at depends on several factors. The most important factor affecting the decibel level of human speech is background or environmental noises.
However, the decibel level of a human voice can get much higher if that person is speaking in a loud voice and very close to your ears. Human shouting or screaming can be dangerous and can even become painful as decibel levels for screams can exceed 120 dB.

Hyperacusis is a type of reduced tolerance for sound. People with hyperacusis often find ordinary noises too loud, and loud noises uncomfortable or painful. The most common cause of hyperacusis is damage to the inner ear from ageing or exposure to loud noise.
If your hyperacusis is severe, you may find that you are uncomfortable leaving your home, and that your reduced tolerance for sound is affecting your career and social life. Some people find that everyday activities, such as driving a car, using a lawn mower, vacuum cleaner or power tool, watching the television or listening to music are problematic. Shopping centres, restaurants and movie theatres may be too loud.
Indeed, one of my teachers had this amusing habit of talking out loud to himself. Essentially offering a running play-by-play of whatever he was doing at the moment, whether he was sharpening a pencil, typing hunt/pecking out an email, or packing the trunk of a car.
Or is there something about talking out loud that is actually productive and helpful? Perhaps even when it comes to practicing, and solving problems we might encounter in our concerto or orchestral excerpts?
Observation #2: If instead we focus on what we are doing and why we are doing it (whether we verbalize these things out loud or not), we can not only solve problems more efficiently, but also transfer those solution to similar new problems we might encounter in the future (thereby solving those problems more quickly, with fewer unnecessary mistakes as well). 041b061a72
