Directivity Index. The directivity factor D may be defined as the ratio of the intensity of a source in some specified direction (usually along the acoustic axis of the source) to the intensity at the same point in space due to an omnidirectional point source with the same acoustic power ... The directivity factor indicates how much more effectively a directional source concentrates its available acoustic power into a preferred direction. The directivity index DI is simply 10 times the log of the directivity factor.
