Create pure 40hz light and sound custom session?

I want to get as close as possible to the recent study using 40hz light and sound in mice. It doesn't appear that they used binaural beats or isochronic tones or anything fancy, just a clicking 40hz sound. I want a 60 minute long session that is just straight 40hz flashing light(all colors and same in both eyes) exactly matched with a raw just straight up 40hz tone and nothing else. Could anyone create this, or help me figure out how to create this?
