Question

Eavesdropping! Learning Goal: To apply Problem-Solving Strategy 12.2 Sound intensity. You are trying to overhear a most interesting conversation, but from your distance of 10.0m , it sounds like only an average whisper of 20.0dB. So you decide to move closer to give the conversation a sound level of 60.0dB instead. How close should you come? The values of intensity at the points of interest are not given explicitly. Instead you are given the values of the intensity level at those points. Construct a convenient expression for the intensity I that corresponds to an intensity level beta with respect to a reference intensity I0. Express your answer in terms of some or all of the variables beta and I0.

Part (B):

= 10 log(I/I0)

==> I = I0 * 10^(/10)

Note that the answer must be in terms of and I0
