(Turkish Acoustical Society, AUT University; 2007)It is common to assume the wave field to be diffuse in often used simplified calculation procedures in building acoustics, such as Statistical Energy Analysis (SEA) or energy flow methods. It is a well known that such ... -
(International Congress on Vibration and Sound (ICVS), AUT University; 2012)Modelling the vibration of composite structures requires including the effects of uncertain material properties of individual components at mid-frequency. The purpose of this model is to predict the vibration of double-leaf ...

(AUT University; 2011)One difficulty with computing the surge of a floating elastic plate is that Green's function for the boundary value problem has singularities on the boundary and at the corners. This talk will show how to resolve the ... -
(Institutes of Acoustics, Chinese Academy of Sciences and Acoustical Society of China, AUT University; 2008)This paper describes mathematical modelling procedure of the rib-reinforced floor/ceiling structures, which are made up of components with irregular shapes and physical parameters. Exact determination of the vibration of ... -
(The Institute of the Noise Control Engineering of the USA, AUT University; 2006)Chung and Fox previously presented a mathematical/computational model giving good prediction of low-frequency vibration of light-weight timber based floor/ceiling structures (LTFS) made up of: upper plate, joist beams and ... -
(AUT University, New Zealand Mathematical Society (nzmathsoc.org.nz); 2010)Numerical computation of flexural motion of a floating elastic plate is often complicated. The linear approximation of the motion makes the computation tractable for simple harmonic waves in a plate. I will introduce a few ... -

(AUT University, The New Zealand Acoustical Society; 2010)Contrary to common belief, a relatively simple and practical lightweight timber based floor/ceiling can have impact sound insulation superior to that of concrete slab based systems. This paper presents examples of such ... -
(AUT University, ICIAM; 2011)One difficulty with computing the surge of a floating elastic plate is that Green's function for the boundary value problem has singularities at the corners of the boundary. This paper shows how to resolve the integrals ... -
(AUT University, The Australian Acoustical Society. The New Zealand Acoustical Society.; 2006)This talk presents a mathematical model of light weight timber floor/ceiling structures. The structures studied here consist of three basic components, upper plate, joist beams and ceiling. The shape of the whole structure ...
