The effect of extractives on acoustical properties of persian silk wood (Albizia julibrissin)
It was previously reported that extractives from Pernambuco wood (a species from Leguminosae family, native to South America) are positive for acoustical performance of wood. Thus the present study set to investigate the effect of extraction in hot water and ethanol/acetone mixture on acoustical pro...
