Two small speakers are located so that one is 45 cm closer to the listener than the other. What is the lowest possible frequency of sound produced by the speakers for which the interference is destructive at the location of the listener? (Take the speed of sound to be 343 m/s. Assume the speakers are driven by the same oscillator.)
a) 256 Hz b) 220 Hz c) 433 Hz d) 381 Hz e) 306 Hz

Two loudspeakers are located 3.85 m apart on an outdoor stage. A listener is 16.2 m from one and 17.3 m from the other. During the sound check, a signal generator drives the two speakers in phase with the same amplitude and frequency. The transmitted frequency is swept through the audible range (20 Hz to 20 kHz). (a) What is the lowest frequency fmin,1 that gives minimum signal (destructive interference) at the listener's location? By what number must fmin, 1...
Two small speakers are separated by a distance of 6 cm, as shown. The speakers are driven in phase with a sine wave signal of frequency 11 kHz. A small microphone is placed a distance 1.2 m away from the speakers on the axis running through the middle of the two speakers, and the microphone is then moved perpendicular to the axis. Where does the microphone record the first minimum of the interference pattern from the speakers as measured from...
6-1 Two speakers emit sound waves with frequency 4.27 kHz s pts by the same oscillator so that they are in phase with each other. I place the They are driven speakers side-by-side, and I stand across the room from them. If someone moves one of the speakers towards me, I hear the total intensity drop and then rise again. How far had they moved the speaker at the point whereI heard a minimum intensity due to destructive interference of...
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 loudspeakers placed 6.0 m apart are driven in phase by an audio oscillator, whose frequency range is 1399 Hz to 1812 Hz. A point P is located 5.1 m from oneloudspeaker and 3.6 m from the other. The speed of sound is 344 m/s. The frequency produced by the oscillator, for which constructive interference of sound occurs atpoint P, in SI units, is closest to:
Two speakers spaced a distance 1.8 m apart emit coherent sound waves at a frequency of 547 Hz in all directions. The waves start out in phase with each other. A listener walks in a circle of radius one meter centered on the midpoint of the two speakers. At how many points does the listener observe destructive interference? The listener and the speakers are all in the same horizontal plane and the speed of sound is 340 m/s.
Two loudspeakers placed 6.0 m apart are driven in phase by an audio oscillator, whose frequency range is 711 Hz to 1124 Hz. A point P is located 5.1 m from one loudspeaker and 3.6 m from the other. The speed of sound is 344 m/s. The frequency produced by the oscillator, for which destructive interference occurs at point P, in SI units, is closest to: Two loudspeakers placed 6.0 m apart are driven in phase by an audio oscillator,...
Two speakers, one directly behind the other, are each generating a 329-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? Take the speed of sound to be 344 m/s.
Two speakers, one directly behind the other, are each generating a 237-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? Take the speed of sound to be 342 m/s.
28a. Two speakers and a listener are located at positions A, B, and C as shown in the diagram to the right. Both speakers produce an identical 857.5 Hz tone on a 20° C day. Des the listener hear a loud sound, or agreatly diminished sound? Justify your answer with calculations and an explanation. 2.40m 28b. The speakers are now separated by 2.50 m and are vibrating exactly out of phase. These out-of-phase speakers produce the same tone of 551...
