The present article aims to characterize and improve the sound absorption of wood-wool cement boards (WWCB) with varying strand widths, densities, thicknesses and applied with varying air cavity thicknesses by using impedance models. Different rigid-frame impedance models were analysed to predict the acoustic impedance of this material, and their suitability for the WWCB was evaluated. The Johnson-Champoux-Allard...
Stage acoustic parameters are commonly determined in concert halls using omnidirectional transducers, but might be more valid when using directional transducers. In this paper, the sensitivity of stage acoustic parameters to source and receiver directivity has been investigated by measurements on three stages and in two orchestra pits. A single loudspeaker was used with a directivity similar to a...
