Two identical audio speakers connected to the same amplifier produce in-phase sound waves with a single frequency that can be varied between 340 and 575 HzHz . The speed of sound is 340 m/sm/s . You find that where you are standing, you hear minimum-intensity sound
If one of the speakers is moved 39.8 cmcm toward you, the sound you hear has maximum intensity. What is the frequency of the sound?
Express your answer in hertz.
How much closer to you from the position in part B must the speaker be moved to the next position where you hear maximum intensity?
Express your answer in meters.
A loudspeaker having a diaphragm that vibrates at 1250 Hz is traveling at 80 m/s directly toward a pair of holes in a very large wall in a region for which the speed of sound is 344 m/s. You observe that the sound coming through the openings first cancels at 11.4 deg with respect to the original direction of the speaker when observed far from the wall.
How far apart are the two openings? What angles would the sound first cancel if the source stopped moving?
The shortest distance between a sound source (S,) and a reflecting wall is 25 m. The sound is reflected at an angle of a, = 45° to
a listener (L,).
(a) What is the shortest distance between the sound source and the listener, (x1)?
