| Abstract | TEOAEs of 30 normal hearing and 25 hearing impaired human subjects were recorded and analyzed with a PC based system designed and installed in the authors' lab. The 3D visualized results of the time frequency analysis of TEOAE showed that the frequency components of normal hearing subjects were uniquely related to the stimulating sound and individually showed different time patterns. Moderate hearing loss at a certain frequency led to an intensity decrease at similar frequency components of TEOAE. Severe hearing losses eliminate TEOAE. Early TEOAE might be produced before 3 ms, even as early as 1 ms. This implied that the olivo-cochlear bundle was not involved in the initiation control of TEOAE. From research on the short time spectrum, time-frequency relations, and latencies of TEOAE, new approaches for revealing the mechanism of TEOAE can be reached. |

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.
