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...

| description | 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 properties of Persian silk wood (Albizia julibrissin, a species from Leguminosae family, native to Iran). Contactless forced flexural vibration on both freeends of beams was performed on thin small specimens before and after extraction. Results showed that the extractive components soluble in hot water were positively useful to acoustical properties because removing these extractives
reduced the acoustic property of the wood. Raw wood from Persian silk tree based on a combination of studied acoustical characteristics has theoretically the potential to be applied in violin backs and ribs. |
