Colorized Schlieren – with and without face masks

This is my first professional (as opposed to personal) youtube video, on my work channel for Maps of Speech. Today I’m making my debut with a scientific report on colorized schlieren images of speech air flow with and without masks. Please share widely, and encourage others to share widely. This is intended to be a worldwide release, and has been approved by the New Zealand Ministry of Business, Innovation, and Employment’s communications team, as well as our COVID-research team. In general, videos on this channel are more formal than my HoT videos, and will often be made in collaboration with whatever research team is working on the related projects. The details below this video link to three other unlisted videos that show the entirety of the schlieren videos referenced – without any audio commentary.
