Paisley stands in front of two speakers as shown which emit the same tone, in phase. She is 7.00 m from speaker A and 5.00 m fromB speaker B. a. What are the two lowest frequencies for which she hears: i. a loud sound? [171.5 Hz, 343 Hz] ii. a quiet sound [85.8 Hz, 257 Hz] d-5.00m A-7.00m b. The frequency of the speakers is then changed to 686 Hz Does Paisley hear a loud sound or a quiet sound?...

2. A 1,720-Hz pure tone is played on a stereo in an open field. A person stands at a point that is 8 m from one of the speakers and 8.7 m from the other. Does the person hear the tone? (Assume the speed of sound is 344 m/s.) The path difference of _____ is ______ times the wavelength of the tone, giving _________ interference.

Two identical speakers (labeled 1 and 2) are playing a tone with a frequency of 225 Hz, in phase. The centers of the speakers are located 6.00 m apart. Five observers are standing on a line that is 6.00 m in front of the speakers as shown in the figure. Each observer is separated by 1.00 m and Sue is directly in front of speaker 1. Determine which observer or observers will experience constructive interference from the sound emitted by...

5. The temperature is 22 °C. An observer stands directly between two speakers at location M shown below. The speakers are situated 120 m apart, The two speakers are emitting the same 650 Hz sound, but 0.75λ out of phase. (a) what distance, x, would the observer have to move for the waves to be in phase? (b) What values will R2 and R1, have after the move? MAR

Two speakers emitting identical tones are separated by 3.0 m. A person sits 4.0 m away from one of the speakers. The line from the person to the speaker makes a right angle with the line joining the two speakers. Determine the frequency of the lowest pure tone that will result in a. constructive interference b. destructive interference
Two speaker emit the same pure tone at 170 Hz, but they are half a cycle...
Two speaker emit the same pure tone at 170 Hz, but they are half a cycle out of phase with each other (so one produces a "trough" exactly when the other one produces a "crest"). The speakers are three meters apart. You are standing between the speakers, one meter from one (and therefore two meters from the other). What do you hear? The speed of sound in air is 340 m/s. O A 170 Hz tone, but very quietly, if...
Question 5 Two speakers are placed 5m apart, are both forward facing, and emitting sound in...
Question 5 Two speakers are placed 5m apart, are both forward facing, and emitting sound in phase, with a frequency of 1000 Hz. A person is standing in front of the speakers, a distance of 20 m from the mid point between the speakers. If the person walks parallel to the speakers (sidewards), how far do they need to walk before they hear a maximum, after walking through a minimum? What angle does this make relative to the perpendicular of...

11) Two loudspeakers, A & B are emitting waves of the same frequency (f= 1021 Hz) in a room where the speed of sound is measured to be v 343 m/s. a) What is the wavelength of the sound emitted by the speakers? 4.0 m1.5 m 2.0 m If a person at point P determines that the waves from the two speakers interfere destructively (it is quiet at point P), are the waves emitted from the speakers in phase or...

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 speakers, A and B, are 4.00 m apart and are emitting identical in-phase sound waves. The speed of sound in air is 340 m/s. Consider a line which is the perpendicular bisector of the line connecting the two speakers. The first interference maximum occurs at ±25.15 o from this line. (a) What is the frequency of the sound emitted? (b) Find the rest of the angles where constructive and destructive interference occur. (c) If the speakers are aboard a...
