Abstract
An apparatus for and method of characterizing an acoustic field, and particularly of visually characterizing the field. An acoustic receiving transducer means is moved to a plurality of predetermined coordinate and angular positions in the acoustic field, and for each such position an electrical signal indicative of a parameter of the acoustic field is stored in a memory. The information in the memory is selectively retrieved to activate an electronic display means, and to expose film if desired, to provide a visual 'map' of the acoustic field parameter detected.
