The two speakers of a boom box are 30.8 cm apart. A single oscillator makes the speakers vibrate in phase at a frequency of 2.16 kHz. At what angles, measured from the perpendicular bisector of the line joining the speakers, would a distant observer hear maximum sound intensity? (Take the speed of sound as 340 m/s. Consider nonnegative angles only. Enter your answers from smallest to largest. Enter NONE in any unused answer blanks.)
