“…10 Pushed by the increased need of comfort in the transport industry, from the nineties new efforts were devoted to this subject, with new interesting developments and advances in SEA ͑e.g., Refs. 11-14͒, with innovative methods, e.g., Wave Intensity Analysis, vibration conductivity, energy mobility 15 and, more recently, acoustic diffusion models, 16,17 ensemble energy average. 18 In such context the complex envelope displacement analysis is the only method that does not take advantage of an energy formulation, but rather it transforms the physical equation of motion into a new one, characterized by a field variable that has a low wave number content so that it can be numerically solved by a coarse mesh.…”

The complex envelope displacement analysis (CEDA) is a procedure to solve high frequency vibration and vibro-acoustic problems, providing the envelope of the physical solution. CEDA is based on a variable transformation mapping the high frequency oscillations into signals of low frequency content and has been successfully applied to one-dimensional systems. However, the extension to plates and vibro-acoustic fields met serious difficulties so that a general revision of the theory was carried out, leading finally to a new method, the complex envelope vectorization (CEV). In this paper the CEV method is described, underlying merits and limits of the procedure, and a set of applications to vibration and vibro-acoustic problems of increasing complexity are presented.
