Two out of phase loudspeakers are some distance apart. A person stands 5.00 m from one speaker and 2.60 m from the other. What is the third lowest frequency at which constructive interference will occur? The speed of sound in air is 339 m/s
Two out of phase loudspeakers are some distance apart. A person stands 5.00 m from one speaker and 2.60 m from the other. What is the third lowest frequency at which constructive interference will occur? The speed of sound in air is 339 m/s.
Two identical loudspeakers are some distance apart. A person stands 5.80 m from one speaker and 3.10 m from the other. What is the lowest frequency at which the person will hear destructive interference? The speed of sound in air is 340 m/s.
Two loudspeakers in a plane are 2.0 m apart and in phase with each other. The speed of sound is 340 m/s. Assume the amplitude of the sound from each speaker is approximately the same at the position of a listener, who is 3.75 m directly in front of one of the speakers. a) (10pts) For what three lowest frequencies will there be a minimum signal (destructive interference)? b) (10pts) For what three lowest frequencies will there be a maximum...
Two loudspeakers placed 6.0 m apart are driven in phase by an audio oscillator, whose frequency range is 711 Hz to 1124 Hz. A point P is located 5.1 m from one loudspeaker and 3.6 m from the other. The speed of sound is 344 m/s. The frequency produced by the oscillator, for which destructive interference occurs at point P, in SI units, is closest to: Two loudspeakers placed 6.0 m apart are driven in phase by an audio oscillator,...
Two loudspeakers are mounted on a rack, one h = 3.42 m above the other. Exactly 8.00 meters to the right of the midpoint, a listener rests at point o. Point O is equally distant from each loudspeaker. 8.00 m The loudspeakers are driven by the same tone generator and vibrate in phase at 510 Hz. It is possible to create a condition of destructive interference at Point O by changing one or both of the path lengths (r, and...
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...
Two in-phase loudspeakers are placed along a wall and are separated by a distance of 6.00 m. They emit sound (take vs = 343 m/s) with a frequency of 137.2 Hz. A person is standing away from the wall, in front of one of the loudspeakers. What is the closest distance x from the speaker the person can stand and hear a sound intensity maximum? 4. [5] Two in-phase loudspeakers are placed along a wall and are separated by a...
Two in-phase loudspeakers are placed along a wall and are separated by a distance of 4.00 m. They emit sound with a frequency of 514 Hz. A person is standing away from the wall, in front of one of the loudspeakers. What is the closest distance from the wall the person can stand and hear constructive interference? The speed of sound in air is 343 m/s. Multiple choice: 1.64 m 1.15 m 0.344 m 0.729 m
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)...
