The relationship of active to reactive instantaneous intensity of a sound wave is expressed by its specific acoustic admittance. This reveals important features of a sound wave under measurement. For example, the direction to a source, the distance from that source, whether the source is a monopole or dipole radiator, and whether the sound under measurement is free field or reverberant, and by how much, is contained in the specific acoustic admittance. Preliminary measurements utilizing time delay spectrometry (TDS) are presented and discussed.
