Developing countries like India, where doctor to patient ratio is around 1:1700, as large number of population lives in villages and remotely located area. Health checkup of such a large population is very challenging for their government due to less number of qualified doctors, highly qualified doctor refuges to work in villages and remotely placed areas. This paper proposes a new idea by which an electronic stethoscope is used to provide health checkup of such large population, by creating a public health center (PHC) in every village or combining more small villages to one PHC and connecting it with authorized center, authorized center monitors more than fifteen PHC. Recording of human organ signal by using stethoscope and transmitted to the authorized center using electronic mail can reduce the requirement of large number of doctors.

“…Jatupaiboon et al in 2010 proposed a prototype for storing the heart beat sound filtering it by means of low pass filters, the purpose of this paper was focused on reducing the noise from the said data (Tang et al in 2010), proposed a wireless electronic stethoscope by using Bluetooth in integration with embedded processors for displaying the data on LCD and storing the data for computer-aided diagnosis. (Harsola et al 2011) suggesting that the stethoscope should be physically connected and data will be sent through Lab View [5]. (Gururajan et al 2011) conducted a study based on different de-signs of wireless electronic stethoscopes and their feasibility based on user's perspective to identify issues when using these stethoscopes in telemedicine and e-health platforms [6].…”

Acoustic stethoscope is a primary diagnostic tool used by doctors for effective analysis of various diseases. But, it suffers defects such as low level heart sounds and presence of murmurs. This project aims at developing ‘Noise removal in stethoscope using Butterworth filter’. In this, the low level heart sounds were amplified with high gain pre-amplifier circuit. A review of basic filters like low pass RC filter, Butterworth filter, Chebyshev filter and Bessel filter are done for elimination of murmurs and best suited filter is suggested. Finally, amplified noise free heart sounds are simulated using Proteus 7.4. The results prove that efficient filter for designing is ‘Butterworth filter’.

“…Phonocardiogram is non stationary signals which are difficult to analyze and process. There are components in phonocardiogram the first and second heart sounds (S1, S2) are called "lub" and "dub" [2]. These are high frequency sounds which are related to closing and opening of AV valves produce S1, closing and opening of semi lunar valve produce S2 sounds.…”
