“…Therefore this approach is not used here. Another approach, also using a subdivision of the cavity, forces the values of the coupling loss factors to attain an a priori known spatial decay [5]. This approach seems unnecessary, at least for the present problem, since, if the spatial decay throughout the cavity is known, there is no need to subdivide the cavity.…”

The sound field in train compartments, treated as a series of connected air cavities, is modelled using statistical energy analysis, SEA. For the case under study, with five cavities in series and the source in the second cavity, a closed--form solution is obtained. An adjusted SEA model is used to predict the rate of spatial decay within a cavity. The SEA model is validated using results from a ray tracing method and from scale model measurements. For the octave bands 500-4000 Hz, good agreement is shown between the results from measurements, the ray tracing and the SEA model, for the two saloons closest to the source cavity (a vestibule). The SEA model was shown to slightly underestimate the rate of spatial decay within a cavity. It is concluded that a reasonable cause is the additional diffusion due to the seating.

“…Craik [9] describes a method of estimating the vibration level difference, D ij , in a two-leaf lightweight panel by using statistical energy analysis (SEA). The value is computed using the equation where ρ s is the plate density per unit area, η is the damping factor, ω is the frequency, Y is the plate structural input mobility, and n is the number of point connecting ties per unit area.…”

Vibration transmission through structural connections is modelled in a deterministic way by means of modal analysis. This model is used first to study the effect of elastic joints across the floor in the transmission of impact noise. They are an effective means of reducing impact noise propagation, and can almost eliminate it for small values of the joint stiffness. The method is also used to study the acoustic relevance of studs in lightweight floor transmission. Different ways of modelling the studs are presented and compared. For the examples developed, the best option is to use springs for modelling the studs rather than more complex models involving springs and beams. Also the different behaviour of point and line connections is verified, as well as the influence of the position of the studs.

“…Shifting to a new paradigm Until the last decade (with some notable exceptions 3 ), research on sound transmission between rooms in buildings has focused mainly on sound transmission through individual assemblies. This perspective is still evident in North American building codes, which for many decades have considered only the ratings for the assembly separating adjacent dwellings: Sound Transmission Class (STC) or Field Sound Transmission Class (FSTC) for airborne sources 4 or Impact Insulation Class (IIC) for footstep noise 5 .…”

Standardized frameworks for calculating the overall transmission including structure-borne flanking, combined with standardized measurements to characterize sub-assemblies, have advanced these issues from research concepts to engineering practice in many countries. From studies of relatively homogeneous and isotropic constructions of concrete and masonry in the 1990's, the technology is now expanding to include the more complicated behavior of lightweight framed constructions. These advances in measurement-based calculations offer the potential for better design based on comprehensive prediction of sound transmission between units in multifamily buildings. To realize that potential, we still must overcome several challenges. First, the acoustical prediction tools must be suitable for designers who integrate the many aspects of building performance. Second, the acoustical metrics must properly reflect how occupants respond to transmitted sound from both typical airborne sources and impact sources such as footsteps. These concerns pose major challenges for the next decade -both for research and for implementation.
