| Abstract | The stethoscope has been used for almost two centuries mainly for listening to the lung and heart sounds. This study was conducted to characterize the frequency contents of the breathing sounds recorded with an electronic stethoscope under different conditions. These conditions included different levels of pressure applied to the probe and the use of a double-sided adhesive tape for interfacing. The goal of this study was to quantify the differences in frequency response and assess the attenuation of high and low frequencies caused by the probe-skin interface during testing. Various pressures were applied and quantified using a pressure-sensing handle developed in conjunction with this study. The signal was analyzed by using the Fast Fourier Transform (FFT) implemented in MATLAB. The data showed significant differences in frequency response with varying recording methods. The result of this study is useful for controlling the recording method when the acoustic signal from the stethoscope is used in a quantitative way. |

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.
