Directivity factor q. The sound energy from an omnidirectional sound source spreads omnidirectional outwards away from the source. The directiv ity factor q is a simple way to describe the radiated sound from loudspeakers. Fully horn loaded pa speakers for example are very high q and not usually appropriate for residential use.

Directivity factor q is the spl ratio squared at the measured point measured axis to the mean squared spl at the same distance over all directions together. Usually the designated axis is taken as the axis of maximum radiation in which case. A higher q speaker is more directional than a lower q speaker. Directivity then is the maximal.
