Sound Power Measurement
A frequently used method of estimating the sound power level at a source is to measure the sound pressure level at some distance, and solve for :

or
- if the source is on the floor or on a wall, such that it radiates into a half sphere.
The sound power estimated this does not diminish or increase with distance, unless reflections are present.
