Question: What is the difference between sound intensity and sound intensity
What is the difference between sound intensity and sound intensity level?
Answer to relevant QuestionsWhere is the intensity greater and by what factor: (1) at a point a distance R from a power source P, or (2) at a point a distance 2R from a power source of 2P? Explain. A person holds a rifle horizontally and fires at a target. The bullet has a muzzle speed of 200 m/s, and the person hears the bullet strike the target 1.00 s after firing it. The air temperature is 72 oF. What is the ...Sound propagating through air 30 oC at passes through a vertical cold front into air that is 4.0 oC. If the sound has a frequency of 2500 Hz, by what percentage does its wavelength change in crossing the boundary? At Cape Canaveral, on blastoff a rocket produces an intensity level of 160 dB as measured 10 m from the rocket. What would be the intensity level at 100 m away? (Assume no energy is lost due to reflections, etc.) Noise levels for some common aircraft are given in Table 14.4. What are the lowest and highest intensities for (a) Takeoff and (b) Landing for these planes?
