Two speakers sit 4.0m apart. Each is playing the same pure tone, of a single frequency sinusoidal sound wave. For simplicity, we can place these on the y-axis at y = +2.0m and at y = -2.0m. You stand on the centerline between the speakers, and 10.0m in front of them (this would be at y = Om, x = 10.0m) At this location, you hear maximum intensity sound, a.k.a. constructive interference. You then walk in the +y direction until you hear a minimum intensity of sound, a.k.a. destructive interference. This happens when you reach y = 2.5m. (Your coordinates would now be x = 10.0, y = 2.5.) If the speed of sound is 340m/s, what frequency are the speakers playing?

Two loudspeakers, placed on opposite walls of a 10m long room, emit pure sine waves at f= 170 Hz coherently. If we were exactly in the middle of the room, where the interference of waves is constructive, what is the shortest distance we should travel towards one of the speakers so that the waves cancel out completely?" Assume that the speed of sound at air is 340 m/s.
Two loudspeakers are placed above and below each other, as in the figure, and driven by the same spice at a frequency of 5.60* 10^2 Hz. An observer is in front of the speakers at point O, at the same distance from each speaker. What max vertical distance upward should the top speaker be moved to create destructive interference at point O? ( assume spread of sound is 343m/s)
Two identical loudspeakers placed 3.00 m apart are driven by the same oscillator (as shown). A listener is originally at point O, located 8.00 m from the center of the line connecting the two speakers. The listener then moves to point P, which is a perpendicular distance 0.350 m from O, and she experiences the first minimum in sound intensity. What is the frequency ofthe oscillator?
The two speakers are placed 40.0 cm apart. A single oscillator makes the speakers vibrate in phase at a frequency of 1.98 kHz.

The acoustical system shown in the figure is driven by a speakeremitting sound of frequency 620 Hz. Take v air =340 m/s.(a) If the upper U-shaped tube is 1.10 m long and the lower Ushaped tube is 1.37 m long, can the person in the picture hear thesound? Why? (b) To change the status (either from louder to softeror from softer to louder), how much the length of the lower Ushaped tube needed to be increased?
A dramatic demonstration, called “singing rods,” involvesa long, slender aluminum rod held in the hand near therod’s midpoint. The rod is stroked with the other hand.With a little practice, the rod can be made to “sing,” oremit a clear, loud, ringing sound. For an 80-cm-long rod,(a) what is the fundamental frequency of the sound?(b) What is its wavelength in the rod, and (c) what is thetraveling wavelength of the sound in air at 20°C?

The figure shows two loudspeakers (A) and (B), and a point (C) where a listener is positioned. The speakers vibrate inphase and are playing a 67.0 Hz tone. The speed of sound is 343 m/s.

Two loudspeakers in a 40 C room emit 650 Hz sound waves along the x-axis. If the speakers are in phase, what is the smallest distance between the speakers for which the interference of the sound waves is destructive?
Two speakers, A and B, are in phase and 2 meters apart on the x-axis. Theyare both emitting a pure tone with a wavelength of 2 meters. How fardirectly in front of speaker B (walking in the y-direction) must you go untilthe first time you experience total destructive interference?
Mr. Daryl is giving an announcement, and he can be heard up to 30m. If you are standing 35m east and 25m south of Mr. Daryl, will you be able to hear his announcement? a. Yes, because I am only about 18.02 meters away from him. b. No, because I am about 43.01 meters away from him. C. Yes, because I am only about 25 meters away from him. d. No, because I am about 35 meters away from him.
