Consider two wave functions y1(x,t)=Asin(kxt) and y2(x,t)=Asin(kx+t+) . What is the wave function resulting from the interference of the two wave? (Hint: sin()=sincoscossin and =2+2 .)
Loudspeakers can produce intense sounds with surprisingly small energy input in spite of their low efficiencies. Calculate the power input needed to produce a 90.0-dB sound intensity level for a 12.0-cm-diameter speaker that has an efficiency of 1.00% . (This value is the sound intensity level right at the speaker.)
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 loudspeakers, placed with respect to an observation point P as shown in the diagram below, emit identical pure tones of f = 343 Hz. The speed of sound in air is 343 m/s. The minimum speaker separation s for experiencing complete destructive interference at P is s = m.
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?
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)
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 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 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?
Two out of phase loudspeakers are some distance apart. A person stands 5.40 m from one speaker and 3.20 m fromthe other. What is the second lowest frequency at which constructive interference will occur? The speed of sound in air is346 m/s.
In a two-point source interference pattern in a ripple tank, a point is one wavelength farther from one sourcethan the other. If the two sources are in phase, then there isa. destructive interference at this pointb. constructive interference at this pointc. both constructive and destructive interference simultaneouslyd. neither constructive nor destructive interference at this pointe. no interaction between the two waves at this point
Two loud speakers are 3m apart. A person is listening to a single pitch at 680Hz. Theperson is along the back wall, which is reasonably far, what are two directions from the center ofthe speakers where the person would expect to have the music loud? Repeat for two directionsthat are quiet.The person is now standing at the location that is 4m directly in front of one of thespeakers. Determine whether that position is loud, quiet or somewhere between the twoextremes. Explain. Use a diagram to help. [Note: Do not assume the person is far away.Comment on why that makes a difference.]
