What is the power of a sound wave (B = 32 dB) passing through an area of 12.5 cm^2? Suppose the same sound wave passes through an area of 25 cm^2. What is it's intensity level?
Please explain to me how to use the Definition of Intensity level Beta
B= 10 log (I/Io) in this problem.
In six lines of computations, the problem is solved.
