A point source of sound generates a 200 Hz tone. The wave has an intensity of 2.2×10−8 W/m2 at a distance of 3 m from the source. Find the total sound power at the source. At what distance from the source is the decibel level below 15 dB? What is the intensity of the sound at this distance?
4 A point sound source emits a sinusoidal wave at a frequency of 2,000 Hz. The pOwer of the sound at the source is 10 watt. What are: the sound intensity, the sound intensity level and the loudness of that sound at (a) a distance of Im from the source? (b) at a distance of 2m from the source?
A sound wave radiates from a source in all directions. If the power of the sound source is 200 watts, then the intensity level of the sound wave 1000 m from the source is (in dB)
the source of a sound wave has a power of 5.55 microwatts , if it is a point source what is the intensity and the sound level at a 5.86 m distance
A sound wave from a siren has an intensity of 106.4 W/m2 at a certain point, and a second sound wave from a nearby ambulance has an intensity level 9 dB greater than the siren's sound wave at the same point. What is the intensity level of the sound wave due to the ambulance? dB
A sound wave from a siren has an intensity of 106.1 W/m2 at a certain point, and a second sound wave from a nearby ambulance has an intensity level 11 dB greater than the siren's sound wave at the same point. What is the intensity level of the sound wave due to the ambulance? Answer in dB
Question 8 Consider a source emitting sound at frequency f. The speed of sound wave in the medium is v. (a) Show that the Doppler frequency is for a stationary observer as the source approaches at speed v 12 marks (b) Show that the Doppler frequency is f for a stationary observer as the source recedes at speed v, [2 marks (c) Show that the Doppler frequency is vv as the observer and the source are travelling towards each other...
QUESTION The power output of a sound system is increased by a factor of 25. By what factor should you adjust your distance from the speakers so the sound intensity is the same? PRACTICE IT Use the worked example above to help you solve this problem. A small source emits sound waves with a power output of 82.9 w. (a) Find the intensity 3.05 m from the source. W/m2 (b) At what distance would the intensity be one-fourth as much...
