Two compact sources of sound near each other produce in-phase sine waves ateach source. One source is positioned at a distance x, =12.00 m from a microphone2.and the other source is positioned at a distance of x, =13.40 m from the samemicrophone. The amplitude of the sound at the microphone from each source by itselfis s = 0.0350 um. The plane waves come from essentially the same direction so therewill be interference.b. When both sources are on, interference changes the total amplitude tos, = 2s, cos(dS/ 2). What is the total amplitude for the phase difference found inpart 'a.'?

Two speakers sit 4.0m apart. Each is playing the same pure tone, of a single frequency sinusoidal sound wave. For simplicity, we can place these on the y-axis at y = +2.0m and at y = -2.0m. You stand on the centerline between the speakers, and 10.0m in front of them (this would be at y = 0m, x = 10.0m) At this location, you hear maximum intensity sound, a.k.a. constructive interference. You then walk in the +y direction until you hear a minimum intensity of sound, a.k.a. destructive interference. This happens when you reach y = 2.5m. (Your coordinates would now be x = 10.0, y = 2.5.) Interference is based on path length differences form different sources to the same detection point. Identify the paths from the two different speakers to the first observation point (10,0). How long is each of these paths?
An enclosed chamber with sound-absorbing walls in Chamberlin Hall has a 2.0m x 1.0m opening for an outside window. A loudspeaker is located outdoors, 87 m away, and facing the window. The intensity level of the sound entering the window space from the loudspeaker is 79 db. Assume the acoustic output of the loudspeaker is uniform in all directions and that the acoustic energy incident upon the ground is completely absorbed and therefore is not reflected into the window. The threshold of hearing is 1.0 x 10 -12 W/m2. What is the acoustic power entering through the window space
Two audio speakers are placed on a vertical rail. Speaker A is placed at head-level while Speaker B is place at some variable height, Ay, above Speaker A. Both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.759 meters. Calculate the lowest height that Speaker B can be placed above Speaker A to produce a minimum of sound heard by person standing Ax = 4.50 meters directly in front of Speaker A. sy AX Image size: S M L Max
In the figure, sound waves A and B, both of wavelength 12.0 m, are initially in phase and traveling rightward. They each reflect several times but end up traveling in their original direction. What is the second smallest value (m) of d that puts A and B exactly out of phase with each other after the reflections? A B d 2d |—a—
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 intensity detector can be moved along a straight track. a source of spherical waves is placed at one end of the track. When the detector is 2 m away from the source, it measures an intensity of 80 W/m2. What distance do we need to move the detector from that position to get a measurement 13 dB lower? Answer: 6.95m
Two students are standing the same distance from a source of sound. The first student receives a power of 68 × 10-6 W in their eardrum. The second student receives σ = 1.2 times more power in their eardrum. What is the ratio of the diameters of the students eardrums? d1/d2= If the second students eardrums have a diameter of d=1cm what was the intensity of the sound that the student heard in watts per square meter?

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).
Two speakers are a distance d = 19.95m apart and emitting in-phase sound of frequency f = 55Hz. The sound is traveling at a speed of v= 339.8m/s. If a person starts by standing at one of the speakers and walks towards the other one, what is the shortest distance they can walk to find a point in which they hear destructive interference? 6.5 m
