Saw this done on a course so ordered some to make our own. Simply run it from a signal generator set to 40Hz or so ( needs a bit of playing to get right frequency) then connect a couple of receivers to a dual trace oscilloscope. You can demonstrate constructive and destructive interference, and measure the wavelength to work out the speed of sound
