Washington: A new way of studying the breath that comes out of one’s mouth while speaking or singing has been developed. This will not only make it easier to find out how diseases like corona spread but it can also help in evaluating the effect of face masks. The study, published in the journal ‘Applied Optics’, estimates the temperature difference between the breath exhaling from the mouth and the surrounding air, but also how far the breath goes before it spreads to the surrounding air. is.
According to Thomas Moore, author of the study, who hails from the US-based Rollins College, “The new technique can also be used to study how the mouth breathes during speaking and whether it is used during music.” Instructions may be given or in speech therapy.
Indeed, this research was developed to study the flow of air through musical instruments. Moore said the new technology that has been developed is based on the fact that the speed of light changes depending on the temperature of the air. Since the breath is warmer than the surrounding air, the light that comes out during breathing reaches the camera a little earlier than the original light. It can be used to create wind images.
According to Moore, this technique can help determine what kind of mask we should wear while outside the home and how much physical distance we maintain. He said that the epidemic had caused a lot of financial loss to many musicians and any information that could bring them back on track would be important.
