Apparatus and method for characterizing an acoustic field

摘要

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.
