The acoustics are discussed of a large building divided by arches and columns into 77 coupled ''subspaces'' or rooms. Two models of coupled rooms have been devised to predict acoustical characteristics such as the decay of sound energy density and reverberation time. The first is a general model whi

β¦ Synopsis
The starting point of the investigations presented here is the presentation of sound deformation in a room on the basis of relations occurring between the elements of two sets P and S. All possible acoustic states of the room are assigned to the elements of set P. In this way the so-called space of room acoustic states are obtained. In turn, all possible kinds of sound deformation are assigned to the elements of set S. In this wav' the socalled deformation space is obtained. On the basis of these theoretical considerations, the existence of mutual relations between elements of these sets is shown. Some suggestions are also presented concerning the determination of the room acoustic states based on the classification of the signal deformations.

The purpose of this paper is attenuating harmonic sound transmission through symmetric structures into free space using error signals derived from structural vibration sensors. It is well known that structural modal functions of symmetric structures are clustered to an even function or an odd functi
AbstractΓMethods for determining the distribution of spacings between near-planar dislocation boundaries are discussed. Subsequently, distributions of spacings for these boundaries have been determined for both single crystal and polycrystal samples. Misorientations across the extended planar disloc
## Space transformations are proposed as a mathematically meaningful and practically comprehensive approach to simulate multidimensional random fields. Within this context the turning bands method of simulation is reconsidered and improved in both the space and frequency domains.
