Abstract
AN article on the radiation pattern of the human voice by D. W. Farnsworth (Bell Lab. Rec., 20, No. 12 ; August 1942) gives some of the results of & research carried out in collaboration with H. K. Dunn. Any apparatus that either emits or receives radiations has a directional characteristic or radiation pattern, and the determination of these patterns is a routine procedure in radio and acoustical work. If the device is to receive radiation, the directional characteristic expresses its sensitivity to radiation coming from various directions in space. If the device is to emit radiation, the directional characteristic expresses the power radiated in various directions. In both cases the sensitivity and power in each measured direction may be subdivided into frequencies or frequency bands.
