Humming Notes 1/2-lambda apart

Of course, in some other direction is space (off axis), the two waves would add constructively and the power that didn't go in the forward direction would cause the power in that direction be quadrupled (2 squared). There is no way that the power coming from the sources would 'disappear'.

You could do this much easier with two loudspeakers.
