Two identical loudspeakers separated by distance d emit 200 Hz sound waves along the x-axis. As you walk along the axis, away from the speakers, you don't hear anything even though both speakers are on. What are the three lowest possible values for d? Assume a sound speed of 340 m/s . The answer I get is 0.875, 2.625, 4.375 and mastering physics says its wrong

Course Home <Ch 16 HW Problem 16.56 Part A The sound from a trumpet radiates uniformly in all directions in air with a temperature of 20°C Al a distance of 4.92 m from the trumpet the sound intensity level is 470 dB. The frequency is 589 Hz Use 344 m/s for the speed of sound in air, 1.20 kg/m for the density of air, and 1.00x10-12 W/m for the reference intensity What is the pressure amplitude at this distance?
