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.
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.
Loudspeakers A and B are vibrating in phase and are playing the same tone, which has a frequency of 400 Hz. They are set up as in the figure, and point C is located as shown there. However, the distance between the speakers and the distance between speaker B and point C have the same value d. The speed of sound is 343 m/s. What is the smallest value of d, such that constructive interference occurs at point C? 90
There are two loudspeakers 3.0 m apart and both are playing a 686 Hz tone in phase.The speed of sound is 343 m/s. A person is standing directly in front of one of thetwo loudspeakers as shown in the figure and can only move along a line AB.a) Write the inherent phase difference.b) Write the pathlength difference in terms of x, which is a distance from thespeaker 1 to the person.c) At what distances x (calculate three values corresponding to integersm=0,1,2) from the speaker 1 do you hear a minimum sound intensity?
IP-2 101 speakers with a spacing of one meter between adjacent speakers form a line 100m long on the ground (the x-z plane) onthe x axis. The total power output of all of the speakers is 2,500W. The shape of the wavefront arriving at point P is cylindrical as shown to the right. R=2m 50.0m 50.0m Find the intensity of the sound at point P assuming that all sound energy goes into the cylindrical wavefront shown (not including the two half circles at the ends). Answers IP-1 a) 6.22x10 W/m? IP-2 3.98W/m? b) 1.24x10 W/m? c) 4.97x10?W/m? d) 0.199W/m?
SWI-1 Two speakers are in phase and are both playing a tone with a frequency of 250.0 Hz. A listener starts at the location of speaker 2 and moves along the x axis. At what values of x are the first 3 locations where he will hear an intensity minimum? Hint: these are the n = 0, 1, 2 points of destructive interference. Take the speed of sound in air to be 343 m/s. speaker 1 (0, 4.50m) speaker 2 (0, 0) X
A music song recorded in a studio is stored as a digital sequence on a CD. The analog signal representing the music is 2 minutes long and is sampled at a frequency fs=44100s-1 . How many samples should be stored on the CD? Write the number of samples without commas or dots. Assume that the audio file is mono, or in other words, single channel.
Two identical loudspeakers, A and B, are 2.00 m apart. The loudspeakers are driven by the same amplifier and emit 784 Hz sound waves in all directions. Take the speed of sound in air to be 344 m/s. A small microphone is moved out from point B along a line perpendicular to the line connecting A and B (line BC in the figure) At what distances from BB will there be destructive interference?
Jo and Em are both standing different distances from a speaker that is outputting 4. sound uniformly in all directions. Jo is hearing a sound intensity level of 35.0dB. Em is hearing a sound intensity level of 62.0dB. a. What are the intensities heard by Jo and Em? [Recall that there is a difference in meaning between "sound intensity level" and "intensity".] b. If Jo is 150m from the speaker, how far is Em from the speaker? c. If Em's eardrum is 1.20x10 m? , how much sound energy hits Em's eardrum in 20.0s ?
A 21.9 Hz oscillator is connected to two identical speakers located at a distance d = 10.2 m from each other, as shown in the figure. Paul holds a device that measures sound intensity as he walks from speaker s, to speaker s,. Location P on the figure indicates the location of minimum intensity between s, and s, that is furthest away from s,. How far is location P from speaker s,? The speed of sound is 343 m/s. m S2 d S1
The acoustical system shown in the figure below is driven by a speaker emitting sound of frequency 730 Hz. (Use v = 343 m/s.) If constructive interference occurs at a particular instant, by what minimum amount should the path length in the upper U-shaped tube be increased so that destructive interference occurs instead?m (b) What minimum increase in the original length of the upper tube will again result in constructive interference?
The figure shows a loud speaker A and point C where a listener is. AC= 1m and the angle is 40 degrees. B is somewhere to the left of A. Both speakers are playing out of phase a 65Hz tone. What is the second closest distance to speaker A that speaker B can be located so that the listener hears no sound?
