directivity pattern [də‚rek′tiv·əd·ə ‚pad·ərn]

(engineering acoustics)

A graphical or other description of the response of a transducer used for sound emission or reception as a function of the direction of the transmitted or incident sound waves in a specified plane and at a specified frequency. Also known as beam pattern; directional response pattern.

Directivity Pattern

(1) For a transmitting antenna, a graphic representation in polar coordinates of the dependence of the electric field strength of the radiated wave on the direction of radiation (assuming that the field strength is measured at a large and constant distance from the antenna).

(2) For a receiving antenna, a graphic representation in polar coordinates of the dependence of the electromotive force induced in the antenna on the direction of the incident wave (given a field strength at the antenna location that is equal for all waves incident from any direction).
