The microphone was placed within a rubber tubing as close as possible to the base of the chest piece. A microphone with a 20 Hz вЂ“ 20 kHz frequency range was selected in order to capture all of the low frequencies characteristic of internal body sounds. The sensor includes a standard stethoscope chest piece to amplify acoustic signals and an electret condenser microphone to convert the amplified signals to electrical waveforms. Because of this, a custom sensor was designed and developed to capture heart signals. The quality of the sensor directly impacts the quality of the real-time audio output as well as all analyses performed on the measured waveforms. The stethoscope acoustic sensor was an integral hardware component of the system. Hardware Design & Implementation top Stethoscope Acoustic Sensor A digital stethoscope can be used to assist physicians in analyzing cardiac signals in real time during auscultation to reduce the risks of not detecting certain conditions. Heart murmurs may go unnoticed during routine check-ups since detection relies on the training of physicians, the quality of the equipment used, and the severity of the condition. This project is meant to provide a framework for developing useful embedded CAD tools for cardiac murmur detection. The MATLAB interface also uses the transmitted data to calculate and display the patientвЂ™s average heart rate in beats per minute.

Real-time and recorded data can also be visualized using a MATLAB interface that runs on a separate PC and connects to the stethoscope system via the USART interface on the microcontroller. For the user interface, the system includes a 4-line 20-character wide LCD display and a 16-button keypad. In addition, the stethoscope uses a 1MB external Flash memory chip to record and playback audio waveforms.

The captured signals are outputted via pulse-width modulation to a standard 3.5 mm audio socket for real-time auscultation. The system uses a custom-built sensor to capture heart sounds at 8 kHz and converts them to electrical signals to be processed by an ATmega644 microcontroller. The purpose of this project was to design and implement a digital stethoscope to serve as a platform for potential computer aided diagnosis (CAD) applications for the detection of cardiac murmurs. Therefore, the present study indicated that the surface water sources are the main causes of cholera and reestablished the Matlab as epidemic area of Bangladesh.'A digital stethoscope that can amplify, play, and record heart signals in real-time.' cholerae O1 serotype which is main cause of cholera from water, phytoplankton and zooplankton samples of pond and rivers. Strong correlation of Vibrios cultural counts with pH, total coliform and faecal coliform heterotropic plate counts and viable but nonculturable (VBNC) counts with only total dissolved solids (TDS) noticed from the results. To confirm, we further did PCR of ompW gene and serology for V. The culturable Vibrios were counted thiosulfate-citrate-bile salts-sucrose agar (TCBS) and taurocholate tellurite gelatin agar (TTGA) plates and viable but nonculturable (VBNC) by direct fluorescent microscopy.

We measured in situ the physicochemical parameters of water using portable meters and counted the Vibrio sp. People of the area are affected by cholera particularly in rainy seasons. Currently a proportion of people living in rural area like Matlab, Bangladesh are dependent on surface water for various purposes to surface water. Cholera is water-borne infectious disease caused by Vibrio cholerae O1 and O139.
