    Two speakers are placed along a wall 3 m apart. They are in phase and emitting the same tone (440 Hz). You are standing somewhere along the opposite wall. Where along the wall should you stand to hear the loudest signal? a) directly opposite either speaker b) to the right or left of the speaker c) in the middle, between the speakers d) the intensity is about the same everywhere along the wall

  • Interference waves of sound

    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...

    Interference with Loudspeakers Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves OUT of phase. The frequency of the waves emitted by each speaker is 172 Hz. You are 8.00 m from speaker A. Take the speed of sound in air to be 344 m/s.(Hint: out of phase means their phase constants differ by pi ) (a) What is the closest you can be to speaker B and be at a point of maximum...

    You are standing 2.50 m directly in front of one of the two loudspeakers shown in the figure. They are 3.00 m apart and both are playing a 686 Hz tone in phase. (Figure 1) As you begin to walk directly away from the speaker, at what distances from the speaker do you hear a minimum sound intensity? The room temperature is 20 ∘C.

    In the figure, two loudspeakers, separated by a distance of d1 = 2.89 m, are in phase. Assume the amplitudes of the sound from the speakers are approximately the same at the position of a listener, who is d2 = 4.08 m directly in front of one of the speakers. Consider the audible range for normal hearing, 20 Hz to 20 kHz. (a) What is the lowest frequency that gives the minimum signal (destructive interference) at the listener's ear? (b)...

    Two identical loudspeakers are placed on a wall 3.00 m apart. A listener stands 5.00 m from the wall directly in front of one of the speakers. A single oscillator is driving the speakers at a frequency of 300 Hz. (a) What is the phase difference in radians between the waves from the speakers when they reach the observer? (Your answer should be between 0 and 21.) rad (b) What is the frequency closest to 300 Hz to which the...

    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?...

    Two identical loudspeakers separated by distance d emit 200 Hz sound waves along the x-axis. As you walk along the axis, away from the speakers, you don't hear anything even though both speakers are on. What are the three lowest possible values for d? Assume a sound speed of 340 m/s . The answer I get is 0.875, 2.625, 4.375 and mastering physics says its wrong
