Two loudspeakers are separated by 2.00 m. The speakers are identical, meaning that they emit sound with equal power, and at the same frequency, 450 Hz. You stand away from the wall, in front of one of the loudspeakers. What is the closest distance from the wall that you can stand and hear constructive interference? The speed of sound in air is 343 m/s. Hint 1: This may seem like a challenging problem (and it is, kind of), but really it is almost the same as Example 2 from L077, so if you follow through that solution (and understand it!) you can solve this problem. Hint 2: What is the condition for constructive interference (it is different from destructive interference)?

Physics Question
A warehouse building has two open doors along one wall as shown in the figure. The walls of the warehouse are lined with a sound-absorbing material. Two people stand at distance L = 103m from the wall with the open doors as shown. A train runs past the warehouse, blowing its horn to produce a loud sound with a frequency of 581 Hz. To person A, the sound of the train is loud and clear. To person B, the sound is barely audible. Assuming that person B is at the position of the first minimum in the sound interference pattern, determine the center-to-center distance d between the doors. Assume room temperature air.

A sound technician is testing the sound acoustics in a theatre for an upcoming music concert. He sets up speakers in different locations and tests the sound levels in various seats in the theater. As he moves down the aisles of the theatre, he notices the pitch of the music gets lower. Which description best explains why the pitch gets lower as the technician moves away from the speakers in the theater? a Diffraction between speakers b Interference of sound waves c Decrease in wave frequency d Increase in wave frequency
I need help on the last two parts. Thank you!
Sound (speed = 343 m/s) exits a diffraction horn loudspeaker through a rectangular opening like a small doorway. A person is sitting at an angle a off to the side of a diffraction horn that has a width D of 0.068 m. This individual does not hear a sound wave that has a frequency of 8400 Hz. When she is sitting at an angle of a/2, the frequency that she does not hear is different. What is this frequency? Number i Units
Two loudspeakers, 1.7 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? Assume room temperature of 20∘C.
9. Two small stereo speakers are driven in step by the same variable- frequency oscillator. Their sound is picked up by a microphone arranged as shown in the figure. For what two lowest frequencies above 100 Hz does their sound at the speakers produce (a) constructive interference and (b) destructive interference? (Given sound speed 345 m/s.) 2.00 m 4.50 m Microphone
Two loudspeakers on a concert stage are vibrating in phase. A listener is 52.5 m from the left speaker and 24.0 m from the right one. The listener can respond to all frequencies from 20 to 20 000 Hz, and the speed of sound is 343 m/s. What are the two lowest frequencies that can be heard loudly due to constructive interference?
Needs Complete typed solution with 100 % accuracy.
The sound pressure level at 250 Hz is 50 dB in one room and in 30 dB in the other. The surface area of the wall between them is 15 m2. The total amount of absorption at 250 Hz in the room with the lower noise level is 20 Sabines. What is the sound reduction index of the separating partition at 250 Hz:a. 20.0 dBb. 17.5 dBc. 18.8 dBd. 44.8 dB
An audio system is emitting a sound at a frequency of 676 Hz through two speakers separated by a distance d = 0.620 m. What's the shortest distance for a person to hear maximum intensity if he was facing the speaker on the right (see picture).
