Two identical audio speakers connected to the same amplifier produce in-phase sound waves with a single frequency that can be varied between 340 and 575 HzHz . The speed of sound is 340 m/sm/s . You find that where you are standing, you hear minimum-intensity sound
If one of the speakers is moved 39.8 cmcm toward you, the sound you hear has maximum intensity. What is the frequency of the sound?
Express your answer in hertz.
How much closer to you from the position in part B must the speaker be moved to the next position where you hear maximum intensity?
Express your answer in meters.
Imagine you are in an open field where two loudspeakers are set up and connected to the same amplifier so that they emit sound waves in phase at 688 HzHz. Take the speed of sound in air to be 344 m/sm/s. What is the shortest distance d you need to walk forward to be at a point where you cannot hear the speakers? The forward direction is defined as being perpendicular to a line joining the two speakers and you start walking from the line that joins the two speakers.
Point P is adistance of 8.5 m and 9.5 m from a speaker set. Both speakers emit identical sound waves with a wavelength of 1.0 m.a) If the waves are being emitted from both speakersin-phase, what kind of interference occurs at point P?b) What if the speakers emit waves out of phase by πradians? What interference would occur at P?

The two main loudspeakers on stage are 6.0 meters apart and in phase. They emit equal-amplitude, equal-intensity (Io), sound waves with a wavelength of 1.0m. A seat at point A is 10 m in front of the plane containing the speakers and centered between them. A seat at point B, is 10 m directly in front of one of the loudspeakers. a) In terms of Io, what is the intensity IA at point A and IB at point B? b) Given a choice between point A of B, which seat should you choose for the loudest experience given that they are the same price?arrow_forward6. Two speakers, emitting identical sound waves of wavelength 4.0 m in phase with each other, are located side- by-side 8.0 m apart. A microphone is placed directly in front of the left-most speaker, a distance of 6.0 m in front of it. (a) What is the path difference for waves from the two speakers to the point where the microphone is placed? (b) At the location of the microphone will the sound waves interfere constructively, destructively, or some- thing in between? (c) The microphone is moved 9.0 m further away from (but still directly in front of) the left-most speaker, for a total distance of 15.0 m from that speaker. What are the path difference and expected type of inter- ference at the microphone's new location?arrow_forward
- Two loudspeakers are mounted on a wall, one h = 3.46 m above the other. Exactly 8.00 meters to the right of the midpoint, a sensor rests at point O. Point O is equally distant from ea loudspeaker. 8.00 m h The loudspeakers are driven by the same tone generator and vibrate in phase at 430 Hz. It is possible to create a condition of destructive interference at Point O by changing one or both of the path lengths (r, and r,) between speaker and sensor. Suppose that this is done raising the upper speaker while leaving the lower speaker in place. What is the smallest vertical distance (in m) that you would need to raise the upper speaker by, in order to create destructive interference at Point O?

- A riverside warehouse has several small doors facing the river. Two of these doors are open as shown in Figure P27.17. The walls of the warehouse are lined with sound-absorbing material. Two people stand at a distance L = 150 in from the wall with the open doors. Person A stands along a line passing through the midpoint between the open doors, and person B stands a distance y = 20 m to his side. A boat o the river sounds its horn. To person A, the sound is loud and clear. To person B, the sound is barely audible. The principal wavelength of the sound waves is 5.00 m. Assuming person B is at the position of the first minimum, determine the distance d between the doors, center to center.arrow_forwardYou are seated on a couch equidistant between two speakers. The speakers are 2.0 m apart and you are seated 4.0 m away from the point between the speakers as shown in Figure P35.4. Both speakers play an A note (a constant frequency of 440 Hz) in phase and at the same volume. As you move left and right along the couch, you notice that the volume alternates between minimum and maximum due to interference effects. Assume the speed of sound is 343 m/s. a. When you are seated at the center of the couch, is the sound a maximum or minimum in volume? b. If you slide along the couch to the left or right, approximately how far do you need to move until you reach the next location that has the same volume? (Hint: You may wish to obtain an exact expression and then use a spreadsheet or trial and error to find an approximate solution.)
