This picture shows a top view of a person with a set of 12 speakers around the person. Which speaker has the same interaural time difference as speaker #11, reaching the left ear before the right ear?
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?
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?
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)
In the figure, S1 and S2 are two isotropic point sources of sound. They emit waves in phase at wavelength 0.50 m; they are separated by D = 1.58 m. If we move a sound detector along a large circle centered at the midpoint between the sources, at how many points do waves arrive at the detector (a) exactly in phase and (b) exactly out of phase?
One clue used by your brain to determine the direction of a source of sound is the time delay t between the arrival of the sound at the ear closer to the source and the arrival at the farther ear.Assume that the source is distant so that a wavefront from it is approximately planar when it reaches you, and let D represent the separation between your ears. (a) If the source is located at angle u in front of you , what is in terms of D and the speed of sound v in air? (b) If you are submerged in water and the sound source is directly to your right, what is t in terms of D and the speed of sound vw in water? (c) Based on the time-delay clue, your brain interprets the submerged sound to arrive at an angle u from the forward direction. Evaluate u for fresh water at 20C.
Two speakers producing the same frequency of sound are a distance of d apart. Consider an arc along a circle of radius R, centered at the midpoint of the speakers, as shown below. (a) At what angles will there be maxima? (b) At what angle will there be minima?
Two speakers, speakers 1 and 2, located 0.750 m apart from each other, are creating sound waves with an identical frequency of 686 Hz and are in phase. Assume the speed of sound in the room is 343 m/s. Your ear is directly in line with the speakers. a) Do you hear a sound with maximum intensity, a sound with minimum intensity (ideally no intensity), or something in between at your location? b) You now go and stand directly in between the two speakers (0.375 m to the right of speaker 1 and 0.375 m to the left of speaker 2). Do you hear a sound with maximum intensity, a sound with minimum intensity (ideally no intensity), or something in between at your location?
Two loudspeakers are placed above and below each other, as in the figure below, and driven by the same source at a frequency of 4.40 ✕ 102 Hz. An observer is in front of the speakers (to the right) at point O, at the same distance from each speaker. What minimum vertical distance upward should the top speaker be moved to create destructive interference at point O? (Let h = 2.58 m and use v = 343 m/s.)
Please select the correct multiple choice answer from the picture and explain.
Draw a figure to show the resultant wave produced when two coherent waves (with equal amplitudes x) interact in phase. What is the amplitude of the resultant wave? If the phase difference between the coherent waves is changed to 60º, what will be new amplitude?
You and your team are asked to determine the hearing safety parameters for a loud experiment. Sincethe sound will persist for only a short time, the allowed intensity level that will not result in permanenthearing damage is 135 dB. The experiment consists of a single source with power output of 550 W thatprojects sound isotropically (i.e., uniformly in all directions)a) At what distance should you set the safety perimeter (i.e., the radius of a sphere in meters) centered atthe source? b) Where should you set the perimeter is the power of the source doubles?
