Abstract
Movies that show the experimental setup and the full 85-minute observation of speech droplet nuclei. The full movie recording of highly sensitive laser light scattering observations that indicate loud-speaking generates, in addition to hundreds of regular droplets, also many thousands of micro-droplets per second. This movie clip shows the decay of airborne particles. Note: some parts of the audio of the clips were muted for privacy.
