An ambulance is approaching you at 28 m/s, sounding its siren at a frequency of 700 Hz? If the speed of sound is 340 m/s, what frequency do you observe? Your velocity is 0 m/s.
Walking between classes, you have probably heard the loud warning sirens that signal approaching storms. These sounds issue from tall poles placed around Clemson University. The sirens produce a sound that has an intensity level of 90 dB at a distance of two meters. If we treat the siren as a point source of sound, what would the intensity level heard by a stationary observer at 20 meters from the siren be? If the frequency of the tone is 2200 Hz, what frequency will an observer driving at 20 m/s towards the pole hear?
A helicopter drops a paratrooper carrying a siren that emits a 576 Hz audible signal. A microphone (receiver) on the helicopter mon- itors the signal from the transmitter as the paratrooper falls. If the perceived frequency becomes con- stant at 401 Hz, what is the terminal speed of the paratrooper? Assume the paratrooper always remains below the helicopter and the velocity of sound in air is 343 m/s. Answer in units of m/s.
What frequency of sound is observed if the 444 Hz source is traveling away from a stationary observer at a speed of 30.2 m/s? (assume the speed of sound in air is 343 m/s)
A train travelling at 14.47 m/s is receding from a stationary observer, and sounding a warning horn at 249.4 Hz. If the speed of sound is 331.9 m/s, calculate the frequency which the observer hears, in Hz with two digits of precision.
For the scenario in Question 9 with the speed of eagle 11.00 m/s, what frequency does the blackbird hear (in Hz) after the eagle passes the blackbird?
An ambulance whose siren emits a sound wave of frequency 800.0 Hz passes you while you are standing (at rest) on a sidewalk. As it the ambulance moves away from you, the frequency that you hear is 715.8 Hz. Determine how fast the ambulance is moving.
