摘要:
Problems in the combined statistical description of scalar (pressure, potential and kinetic energies) and vector (particle velocity of the medium, energy flux density) acoustical variables in Gaussian random fields are investigated. Spatial and space-time relations are given for the generation of an acoustic field by harmonic and narrowband signals, respectively.
