Question

Two speakers, one directly behind the other, are each generating a 215-Hz sound wave. What is the smallest separation distance between the speakers that will produce destructive interference at a listener standing in front of them? The speed of sound is 338 m/s. m Additional Materials Section 17.2 CJ10 17.P.012. A speaker has a diameter of 0.25 m. (a) Assuming that the speed of sound is 343 m/s, find the diffraction angle ? for a 2.0-kHz tone. (b) What speaker diameter D should be used to generate a 5.0-kHz tone whose diffraction angle is as wide as that for the 2.0-kHz tone in part (a)?
