Two loudspeakers are separated by a distance of 1.36 m. They are connected to the same amplifier and emit sound waves of frequency 1.0 kHz. How many maxima in sound intensity would you hear if you walked in a complete circle around the loudspeakers at a large distance from them? Assume that the sound waves are emitted isotropically.

    1. Two loudspeakers 6.0 m apart are playing the same frequency. If you stand 10.0 m in front of the plane of the speakers, centered between them, you hear a sound ofmaximum intensity. As you walk parallel to the plane of the speakers, staying 10.0 in front of them, you first hear a minimum of sound intensity when you are directlyin front of one of the speakers. What is the frequency of the sound? Assume a sound speed of 340...

    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

    In the figure, two loudspeakers, separated by a distance of d1 = 2.89 m, are in phase. Assume the amplitudes of the sound from the speakers are approximately the same at the position of a listener, who is d2 = 4.08 m directly in front of one of the speakers. Consider the audible range for normal hearing, 20 Hz to 20 kHz. (a) What is the lowest frequency that gives the minimum signal (destructive interference) at the listener's ear? (b)...

    Two speakers, which are separated by a distance d, produce sound waves with the same amplitude, phase and frequency. The frequency of the sound is 570 Hz. You stand a distance of 3.50 m directly in front of the left speaker, on the dashed line shown in the diagram. Assume the speed of sound to be 340 m/s. What is the smallest possible value of d so that you hear no sound because of destructive interference?
