review text: The validity of regarding fluctuating total enthalpy \(H'(x_k,t)\) as a generalized acoustic field, established previously for time-stationary fluid motion fluctuations, is extended by demonstrating that this concept is applicable also to arbitrary fluctuations. For a simple shear flow example, it is shown that the propagation of \(H'(x_k,t)\) through the layer can be significantly affected by the mean Coriolis acceleration and the mean temperature gradient. Reasons are given to support the author's belief that \(H'(x_k,t)\) is the basic generalized acoustic field.
