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.
Two in-phase loudspeakers are placed 6.00 m apart along one wall of a room. They emit sound with a frequency of 512Hz. Starting at the location of one of the loudspeakers, a microphone is moved in a direction perpendicular to the wall until constructive interference is detected for the first time. How far is the microphone from the wall at that point? The speed of sound in air is 330 m/s. a) 0.203 m b) 0.282 m c) 0.664 m d) 0.138 m 0.141 m
A row of seats is parallel to a stage at a distance of 8.4 m from it. At the center and front of the stage is a diffraction horn loudspeaker. This speaker sends out its sound through an opening that is like a small doorway with a width D of 0.074 m. The speaker is playing a tone that has a frequency of 2.00 104 Hz. The speed of sound is 343 m/s. What is the distance between two seats, located near the center of the row, at which the tone cannot be heard?
Two out of phase loudspeakers are some distance apart. A person stands 5.30 m from one speaker and 2.60 m from the other. What is the third lowest frequency at which constructive interference will occur? The speed of sound in air is 338 m/s.
two identical loudspeakers are 3.4 m apart. A person stands 5.8m from one speaker and 3.6 from the other. What is the lowest frequency at which destructive interference will occur at this point? The speed of sound in air is 343m/s/
Sound (speed = 343 m/s) exits a diffraction horn loudspeaker through a rectangular opening like a small doorway. A person is sitting at an angle a off to the side of a diffraction horn that has a width D of 0.068 m. This individual does not hear a sound wave that has a frequency of 8400 Hz. When she is sitting at an angle of a/2, the frequency that she does not hear is different. What is this frequency? Number i Units
An audio system is emitting a sound at a frequency of 676 Hz through two speakers separated by a distance d = 0.620 m. What's the shortest distance for a person to hear maximum intensity if he was facing the speaker on the right (see picture).
For testing purposes, a musical instrument manufacturing company creates a device so that when you blow into one end with your instrument, sound comes out the other end in opposite directions. A sound technician uses a clarinet and generates sound waves with a frequency of 214 Hz. The waves travel in opposite directions in an auditorium, are reflected by end walls, and return. The auditorium is 47.0 m long and the clarinet is located 14.0 m from one end. What is the phase difference (in degrees) between the reflected waves when they meet at the source of the sound? The speed of sound in air is 343 m/s.
A student standing in a canyon yells "echo" and her voice produces a sound wave of the frequency of f=0.54 kHz. The echo takes t=4.8s to return to the student. Assume the speed of sound through the atmosphere at this location is v=328 m/s a) what is the wavelength of the soundwave in meters? b) input the expression for the distance, d, the canyon wall is from the student. (answer should look like 'd='"
Two loudspeakers, 1.0 m apart, emit sound waves with the same frequency along the positive x-axis. Victor, standing on the axis to the right of the speakers, hears no sound. As the frequency is slowly tripled, Victor hears the sound go through the sequence loud-soft-loud-soft-loud before becoming quiet again. What was the original sound frequency?
For testing purposes, a musical instrument manufacturing company creates a device so that when you blow into one end with your instrument, sound comes out the other end in opposite directions. A sound technician uses a whistle and generates sound waves with a frequency of 280 Hz. The waves travel in opposite directions in a sound studio, are reflected by end walls, and return. The studio is 43.0 m long and the whistle is located 14.0 m from one end. What is the phase difference (in degrees) between the reflected waves when they meet at the source of the sound? The speed of sound in air is 343 m/s. 17044.898X See if you can determine the path difference and the wavelength, and then express the path difference in terms of the wavelength. What part of the path difference is of interest to us when finding the phase difference? How is this part of the path difference related to the phase difference? • Need Help? Read It
Two loudspeakers, A and B, are separated by a distance of 2.0 m. The speakers emit sound waves at a frequency of 680 Hz that are exactly out of phase. The speed of sound is 343 m/s. What are the next three distances from speaker A along the +x axis will a points of destructive interference occur?
