The following is the question from my school.
A source emits sound uniformly in all directions. A radial line is drawn from this source. On this line, determine the positions of two points, 1.00m apart, such that the intensity level at one point is 2.00dB greater than the intensity level at the other.
I have no idea what to do because I haven't met a question about determining the positions by dB.
How can I deal with this question?
Thank you for your attention.
