Three phyphoxphones and superposition

If two phyphoxphones at some distance from each other is set to generate a 1000 Hz sound wave (it's uncomfortable but not dangerous I think) then you should get interference/superposition at the same distance (0.34 m) as the local speed of sound (340 m/s).

Is there a way to use a third phyphoxphone to manually find two or three of these maxima/minima? Exact measurement not needed, but a distance that students could confirm looks like about 30 cm would be great.

Anyone tried to do it with "Audio Amplitude"?

I hope it is possible to do with less gear than anno dazumal (see attached png)!

Best regards.
