Experimental study of the energy structure of an acoustic field near a system of sources
Abstract
The energy structure of part of the near field of sound sources was investigated in an anechoic chamber. Particular atention is given to the features of the fine structure of the sound field near the system of sources when the wavelength is comparable to the characteristic dimensions of the system and interference effects lead to a highly complex field structure. Singular points of the streamlines of the active and reactive components of the energy flux density are studied in detail.
