A listener is standing in front of two speakers that are producingsound of the same freqencey and amplitude, except that they arevibrating out of phase. Initially, the distance between thelistener and each speaker is the same (see the drawing). As thelistener moves sideways, the sound intensity gradually changes.When the distance x in the drawing is 0.92m, the change reaches themaximum amount (either loud to soft, or soft to loud). Using thedata shown in the drawing and 343 m/s for the...

I got everything else right except part c, no idea.
Two speakers, emitting identical sound waves of wavelength 1.4 m in phase with each other, and an observer are located as shown in the figure below. (Let x = 5.0 m, and y = 8.0 m.) At the observer's location, what is the path difference for waves from the two speakers? m Will the sound waves interfere constructively or destructively at the observer's location? constructive destructive Suppose the observer now...

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?...

28a. Two speakers and a listener are located at positions A, B, and C as shown in the diagram to the right. Both speakers produce an identical 857.5 Hz tone on a 20° C day. Des the listener hear a loud sound, or agreatly diminished sound? Justify your answer with calculations and an explanation. 2.40m 28b. The speakers are now separated by 2.50 m and are vibrating exactly out of phase. These out-of-phase speakers produce the same tone of 551...

4 15. Two 17.5-mW speakers are situated 4.50 meters apart and playing the same 191.7 Hz tone, but are completely out of phase (Tradians). A listener is stationed at a point 2.40 meters in front of the speaker on the right(B), as shown in the diagram. (3 pts/part) () If the ambient temperature in the room full of a diatomic gas with average molecular mass of 28.94 u is 23°C, what is the wavelength of the sound waves produced by...

6-1 Two speakers emit sound waves with frequency 4.27 kHz s pts by the same oscillator so that they are in phase with each other. I place the They are driven speakers side-by-side, and I stand across the room from them. If someone moves one of the speakers towards me, I hear the total intensity drop and then rise again. How far had they moved the speaker at the point whereI heard a minimum intensity due to destructive interference of...

Two speakers, which are separated by a distance d,
produce sound waves with the same amplitude, phase and frequency.
The frequency of the sound is 570 Hz. You stand a distance of 3.50
m directly in front of the left speaker, on the dashed line shown
in the diagram. Assume the speed of sound to be 340 m/s. What is
the smallest possible value of d so that you hear no sound
because of destructive interference?
