A study of fundamental problems of the wavefields that are the reaction of fluid continuum on two kinds of primary actions in fluid, then on two kinds of elementary point sources, is presented in this paper, based on the assumption of the physical duality of linear fluid mechanics and the formal symmetry of mathematical description. The two fundamental wavefields generated in fluid by physical point sources are discussed in detail, first in the physical perspective. An original approach is next presented to the wavefield mathematics, involving the addition of a concept of time-space coupling operators directly related to source-fluid one-way physical impacts, to the traditional description based on the free-field Green's function. A new perspective on the phenomena, presented in this paper, endeavours to establish the right equilibrium between mathematical formalism and physical phenomenology in the perception of acoustic wavefields.
