Destructive interference near two speakers

[QUOTE="mfb, post: 6315473, member: 405866"] Working with units and formulas would make it easier to understand what you do. x=0.314 m away from the speaker the distance difference is 50m-2*x = 49.382m, that is 9.502 times the wavelength. Looks good. Was the speed of sound part of the problem statement? Assuming a different number here changes the result a lot. 325 m/s would lead to the answer of the professor. That value is a bit on the low side, but not impossible. [/QUOTE]
