Also, the reverse wave-form will have areas of constructive and destructive interference that are difficult to predict and control in an area with lots of reflections, so the speaker will still be heard, and in many cases actually be louder because you added energy to the signal. The size of these areas of interference is related to the wavelength of the sound and it is possible if one ear is in an area of destructive interference, the other will be in an area of constructive interference.

Things equal to nothing else are equal to each other.
