Investigating the effect of canola particles on acoustic properties of particleboard
The effect of the application of different contents of canola particles in the production of particleboard on its acoustic properties were determined using free vibration on free-free bars procedure. 33 samples from each combination of canola and wood particles were prepared and the acoustical prope...

| description | The effect of the application of different contents of canola particles in the production of particleboard on its acoustic properties were determined using free vibration on free-free bars procedure. 33 samples from each combination of canola and wood particles were prepared and the acoustical properties were determined. Results showed that as the content of canola particles in the mixture of the particles increases, the modulus of elasticity and acoustic coefficient of boards increases from 1260 MPa and 2.34 m4/s.kg to 1560 MPa and 2.54 m4/s.kg respectively. At the lower content of canola particles in the particles mixture, because of inhomogeneity, damping factor increased but by increasing the content of canola particles more homogeneous boards was obtained and damping factor decreased. Also, results showed that significant increase in acoustic coefficient efficiency was reached by increasing the content of canola particles. Therefore as the results revealed, incorporating more canola particles in the particleboard mixture, acoustic properties of particleboard improves and the product can be used in acoustic environments, halls and etc. |
