6. Two speakers, emitting identical sound waves of wavelength 4.0 m in phase with each other, are located side- by-side 8.0 m apart. A microphone is placed directly in front of the left-most speaker, a distance of 6.0 m in front of it. (a) What is the path difference for waves from the two speakers to the point where the microphone is placed? (b) At the location of the microphone will the sound waves interfere constructively, destructively, or some- thing in between? (c) The microphone is moved 9.0 m further away from (but still directly in front of) the left-most speaker, for a total distance of 15.0 m from that speaker. What are the path difference and expected type of inter- ference at the microphone's new location?

You are working at an open-air amphitheater, where rock concerts occur regularly. The venue has powerful loudspeakers mounted on 10.6-m-tall columns at various locations surrounding the audience. The loudspeakers emit sound uniformly in all directions. There are ladder steps sticking out from the columns, to help workers service the loudspeakers. Many times, audience members break through the protective fencing around the columns and climb upward on the columns to get a better view of the performers. The upcoming concert is by a group that states that several very-high-volume pulses of sound occur in their concerts, and these sounds are part of their artistic expression. The amphitheater owners are worried about people climbing the columns and being too close to the loudspeakers when these peak sounds are emitted. They do not want to be held responsible for injuries to audience members ears. Based on past performances of the group, you determine that the peak sound level is 150 dB measured 20.0 cm from the speakers on the columns. The owners ask you to determine the heights on the columns at which to mount impassable barricades to keep people from getting too close to the speakers and hearing sound above the threshold of pain.
A room is 6.0 m long and 3.0 m wide. At the front of the room, along one of the 3.0-m-wide walls, two loudspeakers are set 1.0 m apart, with the center point between them coinciding with the center point of the wall. The speakers emit a sound wave of a single frequency and a maximum in sound intensity is heard at the center of the back wall, 6.0 m from the speakers. What is the highest possible frequency of the sound from the speakers if no other maxima are heard anywhere along the back wall?
Figure P24.69 shows a radio-wave transmitter and a receiver, both h = 50.0 m above the ground and d = 6.00 102 m apart. The receiver can receive signals directly from the transmitter and indirectly from signals that bounce off the ground. If the ground is level between the transmitter and receiver and a /2 phase shift occurs upon reflection, determine the longest wavelengths that interior (a) constructively and (b) destructively.

7. When a student tried to set up a home theater system,he arranged two speakers A and B on a wall at a distance 0.845m between them. Now he tried to fix a microphone on the same wall in line with the speakers. The microphone is placed 2.55m from the center points of the two speakers. What is the lowest frequencies of the speakers which will be experienced maximum at the microphone.
Two speakers, speakers 1 and 2, located 0.750 m apart from each other, are creating sound waves with an identical frequency of 686 Hz and are in phase. Assume the speed of sound in the room is 343 m/s. Your ear is directly in line with the speakers. a) Do you hear a sound with maximum intensity, a sound with minimum intensity (ideally no intensity), or something in between at your location? b) You now go and stand directly in between the two speakers (0.375 m to the right of speaker 1 and 0.375 m to the left of speaker 2). Do you hear a sound with maximum intensity, a sound with minimum intensity (ideally no intensity), or something in between at your location?
Consider the speaker set-up in the previous question. Each speaker emits a frequency of 6.6·102 Hz in phase with the other. The listener is seated directly in front of one speaker, 1.6 m away. The speakers are 2.4 m away from each other. How many extra wavelengths are needed for sound to get from speaker 2 to the listener? Take the speed of sound in air to be 3.4·102 m/s.
Two in-phase loudspeakers that emit sound with the same frequency are placed along a wall and are separated by a distance of 5.00 m. A person is standing 12.0 m away from the wall, equidistant from the loudspeakers. When the person moves 1.00 m parallel to the wall, she experiencesdestructive interference for the first time. What is the frequency of the sound? The speed of sound in air is 343 m/s.
A human cannot hear sound at a frequency of 100 kHz or sound at 102 kHz. But if you into a room in which two sources are emitting sound waves, one at 100 kHz and the other at 102 kHz, you'll hear sound. Why? Explain
