1. The problem statement, all variables and given/known data What is the sound intensity of a whisper at a distance of 3.0 m, in W/m^2 ? What is the corresponding sound intensity level in dB? 2. Relevant equations I=P/4*pi*r^2 3. The attempt at a solution I tried looking up what the power of a whisper was and I can't find any information. This would not be a difficult problem if the information was given, but I don't know how to go about it without a value for P. Any help on this subject would be greatly appreciated.
