It is, of course, well known that directional sound collecting systems may be divided into two classes, namely, wave and gradient types. In the case of gradient systems, which depend upon differences in pressure, two major problems are encountered, namely, (1) similarity of frequency response of the units to obtain proper balance, and (2) adequate sensitivity.
