Ergänzungen zur Theorie des schwimmenden Estrichs
The simple theory of the floating floor considers no side boundaries and neglects the possibility of lateral coupling by the elastic interlayer. The theory is improved by introducing the propagation of cylindrical waves in this layer. This concept results in a change of the “stiffness” of the interlayer which can be observed in practice. Only when the finite size and the boundary conditions of the ceiling and the boundary conditions of the floating floor — which are different from those of the ceiling — are considered the deviations of the experimental results from the simple theory can be explained.

- Acta Acustica united with Acustica, published together with the European Acoustics Association (EAA), is an international, peer-reviewed journal on acoustics. It publishes original articles on all subjects in the field of acoustics, such as general linear acoustics, nonlinear acoustics, macrosonics, flow acoustics, atmospheric sound, underwater sound, ultrasonics, physical acoustics, structural acoustics, noise control, active control, environmental noise, building acoustics, room acoustics, acoustic materials, acoustic signal processing, computational and numerical acoustics, hearing, audiology and psychoacoustics, speech, musical acoustics, electroacoustics, auditory quality of systems. It reports on original scientific research in acoustics and on engineering applications. The journal considers scientific papers, technical and applied papers, book reviews, short communications, doctoral thesis abstracts, etc. In irregular intervals also special issues and review articles are published.
