Abstract.The paper aims to present research on the determination of coefficient acoustic absorption as a function frequency, for composite monolayer plates (made of: MDF - wooden dried agglomerated fibres with medium density, RWB rebated wood from beech, PS extruded polystyrene) and multilayer (with outer coatings MDF, polymeric core polystyrene). The sound-absorbing behavior such is highlighted in cabins made structures.
