3-D wave propagation in fluid-filled irregular boreholes in elastic formations
Tadeu, António J. B.; Santos, Paulo F. A.Different seismic testing techniques rely on the propagation of acoustic waves in fluid-filled boreholes from sources placed within the borehole and in the solid media. The interpretation of the signals recorded relies on understanding how waves propagate in the borehole and its immediate vicinity. It is known that very complex wave patterns can arise, depending on the distance between the source and the receiv...
Sound transmission through single, double and triple glazing. Experimental eval...
Tadeu, António J. B.; Mateus, Diogo M. R.Experimental results on sound insulation of glazed openings are reported in this work. The laboratory experiments were performed placing the text specimens between two relatively small rooms. The number of glass panels, their thickness, the air gap thickness between the panels and the type of fixing frame are the variables considered. The insulation conferred by the glazed opening is characterised, identifying ...
