Two speakers, one directly behind the other, are each generating a 329-Hz sound wave. What is the smallest separation distance between the speakers that will produce destructive interference at a listener standing in front of them? Take the speed of sound to be 344 m/s.

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)...

3. Sound a) (5 pts) True or False? i Sound wave does not require a medium to propagate. ii. If the frequency of a sound wave is increased the speed of the sound will increase. iii. The loudness of the sound you hear goes up and down with a regular frequency when there are two sound sources of frequencies that are close but not equal to each other. iv. The fundamental frequency of a tuba is 36 Hz. Considering a...

Two cars are stuck in a traffic jam and each sounds its horn at a frequency of 669 Hz. A bicyclist between the two cars, r= 4.68 m from each horn (see the figure below), is disturbed to find she is at a point of constructive interference. How far backward (in m) must she move to reach the nearest point of destructive interference? Take the speed of sound to be V= 343 m/s

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

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?
