Effect Of Sonication In Designing Of Green Acoustic Material

The proper blending of reinforced material with matrix for fabrication of sound absorbing material in different acoustic based industries has encountered the interfacial problems due to defective alignment of fibrous material. The penetrating nature of ultrasonic wave into atomic and sub atomic region without destroying the characteristic property, it played crucial role in fabrication of effective graded acoustic material. The peculiar structural configuration inside the fibrous material like orange peel have attract the researcher to create special interest in designing of some building acoustic material as well as many technological products. The noise reduction property of orange peel has been improved considerably after ultrasonically mercerization of NaOH.High penetrating and dispersive property of ultrasonic wave to assemble and regrouping among the fibrous material are quite remarkable for enhancing noise attenuation inside the composite. Scanning Electron Microscopy (SEM), Fourier- Transform- Infrared and Thermo-Gravimetric-Analysis of both untreated and treated orange peel indicate the deformation in cellulose as well as anti cellulose with the aid of ultrasonicationpermits the composites to be a suitable acoustic material. The result confirms that ultrasonic treated composite has potential to absorb 88.6% of sound which makes it a Class- B noiseabsorber.
