Sound Intensity Mapping
Sound Intensity is the measure
of acoustic energy passing through a unit area. By integrating over a surface
enclosing an object under test, you can calculate the object's sound power.
This can be done regardless of background noise, allowing convenient, in situ
measurements of sound power. Other advantages of sound intensity measurements
include the ability to determine the directionality of sound, and to quickly
localise noise "hot spots". Mapping software takes this a stage further
by providing you with a contour map of noise levels to provide intuitive documentation
of noise problems.
