The DATS Sound Mapping software package consists of two main facilities:
The first is the sound pressure mapping software. This measures sound pressure from a grid of microphones or from several measurements using a single microphone. The measurements are then used to create a two-dimensional map of the sound emitted by the test piece. The mapping information can be overlaid on a picture of the test item to allow better visualization of the data.
The second is sound power mapping, which uses a sound intensity probe to measure sound intensity at a series of grid points across a test piece. Again, a color or contour map can be created to allow visualization of the sound fields.
