Amplified catalogue of vibration reduction index formulas for junctions based on numerical simulations
(Deutsche Gesellschaft für Akustik e.V. (DEGA), 2016)
Conference report
Restricted access - publisher's policyThe vibration reduction index (Kij) is a key parameter in the prediction of flanking transmissions according to the EN-12354 standard. Formulas for the evaluation of Kij in L, T and X junctions that depend on the mass ratio ... -
Building performance at low frequency range including flanking transmissions
(Deutsche Gesellschaft für Akustik e.V. (DEGA), 2016)
Conference report
Restricted access - publisher's policyRecent researches have proposed alternative formulas for the estimation of the vibration reduction index (Kij) at junctions. Among other aspects, the new approaches propose different expressions for the low, mid and high ... -
Catalogue of vibration reduction index formulas for heavy junctions based on numerical simulations
(2017-07)
Article
Open AccessThe vibration reduction index (Kij) is a key parameter in the prediction of flanking transmissions according to the EN-12354 standard. Formulas for the evaluation of Kij in L, T and X junctions that depend on the mass ratio ... -
Numerical modelling of the radiation efficiency of asymmetrical structures
(2009-05)
Article
Open AccessThe radiation efficiency of a structural element is required by some models in order to predict its sound insulation. A common assumption is that the radiation on both sides of the element is the same. This is not true for ... -
Regression curves for vibration transmission across junctions of heavyweight walls and floors based on finite element methods and wave theory
(2016-12)
Article
Open AccessSound insulation prediction models in European and International standards use the vibration reduction index to calculate flanking transmission across junctions of walls and floors. These standards contain empirical ... -
The role of studs in the sound transmission of double walls
(2009-06)
Article
Open AccessSteel studs are used in double walls to provide structural stability. This creates a vibration transmission path between leaves that can often be more critical than the airborne path through the cavity. Some of the existing ... -
Using spectral finite elements for parametric analysis of the vibration reduction index of heavy junctions oriented to flanking transmissions and EN-12354 prediction method
(2015-12)
Article
Open AccessThe vibration reduction index of heavy junctions is predicted by means of a model based on spectral finite elements. This is equivalent to a finite element method but faster and with smaller computational costs. This ...
