| Abstract | Discarded degummed corn cob husk fiber was used as reinforced material and discarded thermoplastic polyurethane (TPU) particles were used as matrix material. The composites were fabricated by blended mastication-hot processing and the micro-slit plate having excellent absorption acoustic performance was fabricated by processing micro-slit on the composites. Sound absorption properties were studied by changing slit rate, slit width and air cavity depth. The results were choosing a smaller slit rate, a smaller slit width and a larger air cavity depth as possible to improve sound absorption coefficient in low frequency level. The double layer micro-slit plate based on corn cob husk fiber and TPU was designed to broaden sound absorption band and to have a wider application. Theoretical absorption coefficient was obtained through building analytical model and massive theoretical calculation. It was found that it had good agreement with the experimental results. Hence, the analytical model could be adopted to predict the sound absorption coefficient of the double layer micro-slit plate. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
