The intensity of sound at point A a distance of 10 m from the source is 104 watts/m, while the intensity at point B at 1000 m from the source is 10% watts/m. Calculate the intensities at points A and B in decibel. What is the difference between the intensity levels at these two points? The intensity of sound at point A a distance of 10 m from the source is 104 watts/m, while the intensity at point B at 1000 m from the source is 10% watts/m. Calculate the intensities at points A and B in decibel. What is the difference between the intensity levels at these two points?
