You are on a plane traveling on a 23hr flight toFort Wayne from West-Nowhere. The attendantforgets to close the dividing curtains, and fiveminutes after takeoff a two month old baby in1st class starts to scream at 3500.0 Hz with asound level of 122 dB at a distance of 10.0 cmfrom the baby's mouth. Your seat in "last class" is7.0 m (approx. 21 feet away). What is the soundintensity at your ear (in W/m^2)? Assume thebaby is an isotropic source (same at all angles)when radiating sound.

Given: β1=122 dB R1=10 cm=0.1 m R2=7 m

The speed of sound in room temperature (20°C) air is 343 m/s; in room temperature helium, it is 1010 m/s. The fundamental frequency of an open-closed tube is 315 Hz when the tube is filled with air. What is the fundamental frequency if the air is replaced with helium?
From a vantage point very close to the track at a stock car race, you hear the sound emitted by a moving car. You detect a frequency that is 0.855 times smaller than that emitted by the car when it is stationary. The speed of sound is 343 m/s. What is the speed of the car?
A convertible moves toward you and then passes you; all the while, its loudspeakers are producing a sound. The speed of the car is a constant 13.5 m/s, and the speed of sound is 344 m/s. What is the ratio of the frequency you hear while the car is approaching to the frequency you hear while the car is moving away?
A cop car’s siren has a frequency of 750. Hz. If you are driving towards the cop’s siren at a speed of 20.0 m/s, what frequency would you hear? The speed of sound is 343 m/s.
A sound wave in an unknown fluid medium takes 580 μs to travel 3.00 m. What is the bulk modulus of the fluid, if the density is 4.30 x 103 kg/m3? A 1μs is 1 x 10-6s.
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 7.13
A bat emits a sound whose frequency is 81.8 kHz. The speed of sound in air at 20.0 oC is 343 m/s. However, the air temperature is 41.8 oC, so the speed of sound is not 343 m/s. Assume that air behaves like an ideal gas, and find the wavelength of the sound.
You are driving down the highway at a speed of 45 m/s when you hear the sound of a police siren that is 200 m behind you. The frequency you hear is 450 Hz. You know, however, that the actual frequency of a police siren is 425 Hz. What is the speed of the police car? Assume the speed of sound is 343 m/s.
A bird is flying directly toward a stationary bird-watcher and emits a frequency of 1.30 × 10³ Hz. The bird-watcher, however, hears a frequency of 1.37 × 10³ Hz. What is the speed of the bird, expressed as a percentage of the speed of sound?
A physics professor demonstrates the Doppler effect by tying a 450 HzHz sound generator to a 1.0-mm-long rope and whirling it around her head in a horizontal circle at 100 rpm. What is the difference between the highest frequency heard by a student in the classroom and the initial frequency of the sound generator?
You are at BNA (Nashville Airport) watching commercial airliners take off. At a distance of 1,020.6 away from the plane, you record a sound intensity level of 73.4 decibels. If you move such that the new sound intensity level is 88.07 decibels, how far are you away from the plane (in meters)?
