“…At a high-frequency range, the mode of power transmission through structures by a longitudinal wave may however produce a significant value (Cuschieri and McCollum, 1996;Lyon, 1986;Bercin, 1996). Using an energy flow method, Gibbs and Craven (1981) have shown that once a flexural wave impinges on a junction, some parts are converted into an in-plane wave and it can travel through several junctions before converting back to a bending wave. Thus, it may not be appropriate to neglect the contributions of inplane waves in an SEA model.…”

“…Over the past few decades, calculation models predicting structure-borne sound transmission in buildings have almost exclusively been developed by European scientists [1][2][3][4][5][6][7][8]. As a result, these prediction models were originally intended for masonry and concrete buildings, which represent the most common construction type for residential buildings in Europe.…”

Craven et al 6 and Gibbs et al 7 developed a similar calculation model but their approach used a different formulation of the boundary conditions and included the internal loss of the plate material.…”

R. T. Journal of the Acoustical Society of ABSTRACTAn analytical model is presented for structure-borne sound transmission at a bolted junction in a rib-stiffened plate structure. The model is based on the wave approach for junctions of semiinfinite plates and calculates coupling loss factors required by Statistical Energy Analysis. The stiffening rib is modelled as a plate strip and the junction is represented by an elastic interlayer with a spatially dependent stiffness. Experimental verification is carried out on a series of Plexiglas plate structures with varying rib depth and bolt spacing. A well-defined connection length at the junction was created by inserting thin spacers between the plate and the rib at each bolt. Comparison between numerical and experimental data for this case showed good agreement. Measured results for the bolted junction without spacers, suggested that structureborne sound transmission could be modelled as a series of connections characterized by an equivalent connection length. This concept is explored further by determining an optimum connection length which gives the best agreement between numerical and experimental data.
