Abstract
A method and apparatus is disclosed for quantifying an acoustic transducer's directional response that has as its main feature a significant reduction in data complexity. Specific procedures are shown for sound radiating from a source in a flat baffle, a long column or a sphere. A method for extending this reduced representation to systems of transducers of any degree of complexity is also disclosed.

A method for reducing the data required to represent the polar response of a sound radiating device comprising:
- a means for measuring the polar response of the device under test and;
- a means for calculating a modal representation of said polar response and;
- a means for representing the frequency dependence of said modal representation of said polar response and;
- a means for storing said reduced data set.
