person at a concert is 4.15 m from one speaker and 4.35 m from another speaker. The sound produced by the microphone is 1720 Hz. What is the largest wavelegth at which the sound undergoes constructive interference at the location where the person is standing?

Two speakers are against a wall emitting a sound at 767 Hz, 14 m apart, and facing each other. You are standing against the wall in between the speakers. Use 344ms for the speed of sound in air. A) What is the closest distance that you can be from the speaker on the left at which you exprerience total destructive interference, and the sound from the speakers cancel out?  B) What is the closest distance that you can be from the speaker on the left at which you experrience total constructive interference, and the sound intensity is doubled?

Two loud speakers are placed at opposite ends of a field at the same height. Each speaker is broadcastingequally in all directions. The sound intensity is 75.0 dB at the midpoint between the two speakers. Whatis the sound intensity level at a point one-quarter of the way from one speaker to the other along the linejoining them?

At an outdoor music event, a dB meter records 130 dB when placed 2.25 m in front of aloudspeaker near the stage. A) What was the power output of the speaker, assuminguniform spherical spreading of the sound and neglecting any absorption, reflection andinterference of the sound that may occur? B) How far away would you need to be forthe sound level to be 80 dB?

Two loud speakers are 3m apart. A person is listening to a single pitch at 680Hz. Theperson is along the back wall, which is reasonably far, what are two directions from the center ofthe speakers where the person would expect to have the music loud? Repeat for two directionsthat are quiet.The person is now standing at the location that is 4m directly in front of one of thespeakers. Determine whether that position is loud, quiet or somewhere between the twoextremes. Explain. Use a diagram to help. [Note: Do not assume the person is far away.Comment on why that makes a difference.]

Two speakers are a distance d = 19.95m apart and emitting in-phase sound of frequency f = 55Hz. The sound is traveling at a speed of v= 339.8m/s. If a person starts by standing at one of the speakers and walks towards the other one, what is the shortest distance they can walk to find a point in which they hear destructive interference? 6.5 m
