Two small speakers emit sound waves of different frequencies equally in all directions. Speaker A has an output of 1.00 mW , and speaker B has an output of 1.50 mW . Determine the sound level (in decibels) at point C in Figure P 17.30 assuming (a) only speaker A emits sound, (b) only speaker B emits sound, and (c) both speakers emit sound. | Numerade

Figure 17-35 shows two isotropic point sources of sound, S1 and S2 . The sources emit waves in phase at wavelength 0.50 m ; they are separated by D=1.75 m . If we move a sound detector along a large circle centered at the midpoint between the sources, at how many points do waves arrive at the detector (a) exactly in phase and (b) exactly out of phase? | Numerade

Two loudspeakers, 1.0 m apart, emit sound waves with the same frequency along the positive x -axis. Victor, standing on the axis to the right of the speakers, hears no sound. As the frequency is slowly tripled, Victor hears the sound go through the sequence loud-soft-loud-soft-loud before becoming quiet again. What was the original sound frequency? | Numerade

Two loudspeakers emit sound waves of the same frequency along the x -axis. The amplitude of each wave is a. The sound intensity is minimum when speaker 2 is 10 cm behind speaker 1 . The intensity increases as speaker 2 is moved forward and first reaches maximum, with amplitude 2 a, when it is 30 cm in front of speaker 1 . What is a. The wavelength of the sound? b. The phase difference between the two loudspeakers? c. The amplitude of the sound (as a multiple of a ) if the speak- ers are placed s
