- A noisy factory machine produces a sound intensity of 1.00 x 10-5 W/m2 when measured 10 m from the machine. Assume that the sound spreads out uniformly into 3 dimensions for this set of questions. What is the sound power output of the machine? (Give your answer in mW.) What is the decibel level of the machine at 10 m? At what distance is the decibel level equal to 55 dB? (Give your answer in m.)Problem #8: The noise from a grinder in a factory is 32000 times more powerful than the noise from a dishwasher. By how many decibels is the factory noise greater than the dishwasher noise? Problem #9: A loud sound is 90 dB. When the sound is reduced to 5% of its original intensity, what is the decibel level? Problem #10: At a rock concert, a dB meter registered 130 dB when placed 2.8m in front of a loudspeaker on the stage. What is the power output of the speaker, assuming uniform spherical spreading of the sound and neglecting absorption in air? Problem #11: By how many decibels do you reduce the sound intensity level due to a source of sound if you quadruple your distance from it? Assume that the waves expand spherically.A sound wave radiates from a speaker in all directions. If the power of the sound source is 200 W, calculate the intensity level in dB of the sound wave 1 km from the speaker. Hint: Presume that the sound waves spread as a sphere (not a hemisphere).
- according to the barometric measurements, the sound has a decibel level of 180 dB at a distance of 161 km. Assuming the intensity falls off as the inverse of the distance squared, what was the decibel level on the island 4800 km away?The relative intensity of the first harmonic of a sound is 70 dB (1000 Hz). The second harmonic of a sound has the amplitude of a pressure 5 times smaller than that for the first harmonic. What is loudness for the second harmonic if we hear this sound separately?A concert loudspeaker suspended high off the ground emits 45 W of sound power. What is the sound intensity that reaches the an audience member 80 m away from the speaker? units: How many decibels does the audience member hear? units:
- A sound wave having a frequency of 266 Hz travels through air at 20 °C. The decibel level at a distance of 21.3 m from the source is measured to be 77.4 dB. What is the maximum displacement of air molecules at that location? Assume the density of air is 1.20 kg/m³ and that the source produces spherical wave fronts. Express the displacement as a number having the units of mirco meters. 1 micro meter = 1 x 10-6 m. For example, If your calculated answer were 1.873 x 10-7 m, your entry would be the number 0.187 7.13A yoyo of radius R and mass M is released from rest with the string vertical and its top end fixed up a support as shown below.

(b) Without doing the calculation all over again, what is your best estimate value for the sound intensity level at 10 m away, in decibel? On what did you base this estimate? (c) What would be the intensity level in decibel, of two dogs barking at the same time if each delivered 1 mW of power at the distance of 2.5 m?
