Two incoherent sound sources are 2.8 metres apart. They both generate sounds of wavelength 1.87 metres. A listener 2.8 metres from each source hears an intensity of I from each speaker separately. What intensity does he hear if both sources generate sounds simultaneously?
Select one:
a. 4 times I
b. zero
c. 2 times I
d. I
e. one quarter of I
Homework Answers
I = Intensity of sound from each source
= phase difference = 0
resultant intensity is given as
Ires = I + I + 2 sqrt(I) sqrt(I) Cos
Ires = 2 I + 2 I
Ires = 4 I
a. 4 times I

If two sources of sound at frequencies "f1" and "f2" are present, a listener may hear a beat frequency at f_beat = |f1 - f2|. Say your lab instructor turns on two such sources, and tells you f1 = 500 Hz, and that f2 is slightly higher frequency. You hear the combined sound level from the sources get louder and softer, and you measure that it takes 10 seconds for this cycle to repeat 20 times. What is the frequency...

Two sources of sound are located on the x axis, and each emits power uniformly in all directions. There are no reflections. One source is positioned at the origin and the other at x = +116 m. The source at the origin emits four times as much power as the other source. Where on the x axis are the two sounds equal in intensity? Note that there are two answers. xbetween the sources = xnot between the sources = Please...

1. Two loudspeakers 6.0 m apart are playing the same frequency. If you stand 10.0 m in front of the plane of the speakers, centered between them, you hear a sound ofmaximum intensity. As you walk parallel to the plane of the speakers, staying 10.0 in front of them, you first hear a minimum of sound intensity when you are directlyin front of one of the speakers. What is the frequency of the sound? Assume a sound speed of 340...

5. Consider two sources of sound (speakers for example) that are located on the x-axis, each emitting sound uniformly in all directions. There are no echoes and interference isn?t the point of this problem. One source sits at the origin and the other sits at x=+ 186.0 m. The source that is sitting at the origin is 4 times as powerful as the source sitting at +186.0 m. a) Without calculating anything, think about...

Two speakers, 1 and 2, are set up with their centers 6.00 m apart. Both are playing the same tone of frequency 225 Hz, in phase. Five listeners are standing on a line that is 6.00 m in front of the speakers as shown in the figure. Each listener is separated by 1.00 m and Cal is directly in front of speaker 1. Determine which listener or listeners will experience constructive interference from the sound emitted by the speakers. The...

Two compact sources of sound oscillate in phase with a frequency of 100 Hz. At a point 5.00 m from one source and 5.85 m from the other, the amplitude of the sound from each source separately is A. The speed of sound in air is 343 m/s. (a) What is the phase difference of the two waves at that point? (b) What is the amplitude (in terms of A) of the resultant wave at that point?

Two loudspeakers, 5.0 m apart and facing each other, play identical sounds of the same frequency. You stand halfway between them, where there is a maximum of sound intensity. Moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.35 m . Assume the speed of sound is 340 m/s. Part A: What is the frequency of the sound? Express your answer with the appropriate units. Part B: If the...
