1. Two small speakers S are positioned a distance 0.75 m from each other. The two speakers – that are in phasewith each other – are each emitting a constant 2500 Hz in a room with a temperature of 20°C. A student standsat point P, which is 5.0 m from the midpoint between the speakers hears the maximum. The student moves adistance Y to point Q and notices that the sound intensity has decreased to a minimum.Note: The speed of sound in air is given by the formula V = 331 + 0.6T.-5.0 mWhat is the shortest distance that the student could have moved?0.75 mIf the student continues walking from point Q, then how far will he walk to hearthe minimum sound again?

You and your roommate decide to throw a party. You rig up three speakers with a combined decibel level of 83.5 db. You know that speaker one is 78.0 dB and speaker 2 is 76.0 dB. The sticker on the back of speaker 3 is missing, so you will have to calculate how many decibels it is. How many decibels is the third speaker?

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
3. Two loudspeakers emit sound waves along the r-axis. A listener in front of both speakers hears a maximum sound intensity when speaker 2 is at the origin and speaker 1 is at r = 0.50 m. If speaker 1 is slowly moved forward, the sound intensity decrcases and then increases, reaching another maximum when speaker 1 is at x = 0.90 m. a. What is the frequency of the sound? Assume vsound = 340 m/s. b. What is the phase difference between the spcakers?
1. Two speakers are 4.5 meters apart, in phase, and produce a single sound wave with wavelength λ = 0.8m.

In an acoustics lab you have a 60 m long pipe that contains very cold air, in fact T = – 46 °C. Suppose that using a speaker you cause a sinusoidal wave of sound with wavelength 1.5 m to travel down the pipe, going from one end of the pipe to the other. ii) What is the frequency of the sound in the pipe? a) 1.5×102 Hz b) 2.0×102 Hz c) 2.5×102 Hz d) 3.0×102 Hz e) 3.5×102 Hz
3) Two speakers are placed side by side, 4 meters apart and driven by the same frequency of 680 Hz. If the perpendicular distance from a person to one speaker is 3.0 m, is this a quiet spot or a loud spot? Explain your reasoning. The sound speed in the room is 340 m/s. (
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
1. Consider two sinusoidal waves traveling along a string, modeled as y,(x,t) = (0.3m)sin([4m]x+[3s¯]t) and y2(x,t) = (0.6m)sin(18mx-[6s '1). What is the height of the resultant wave formed by the interference of the two waves at the position x=1.1 m at time t=0.6 s? y(1.1 m, 0.6 s) = Note: Assume the phase is in radians.
4. Two side-by-side (virtually no separation) speakers are wired such that they emit a single-frequency sound out of phase with each other by radians, and radially-outward. The tone heard from the two speakers combined has a decibel level of 36 dB. a. If one of the speakers is suddenly disconnected, what is the decibel level heard? b. If both speakers are connected and the listener moves to a distance from the speakers that is 5 times greater than where the 36dB sound was heard, what is the new decibel level heard? Assume that the waves travel radially from the speakers.

A harvest mouse can detect sounds as quiet as -10 dBdB. Suppose you are sitting in a field on a very quiet day while a harvest mouse sits nearby. A very gentle breeze causes a leaf 1.1 mm from your head to rustle, generating a faint sound right at the limit of your ability to hear it. The sound of the rustling leaf is also right at the threshold of hearing of the harvest mouse. How far is the harvest mouse from the leaf?
