Hello,
Came across this little video today that explains a technique for seeing things that we normally cannot see. Sound being one of many of these things. They explain the technique for being able to do this and it appears that this is something most would be able to accomplish if they want to conduct their own studies or if they’re just plain curious.
But, it’s a short video and worth the watch. Very interesting.
Till next time…
