Digital stethoscope
Project Area of Specialization Biomedical EngineeringProject SummaryA digital stethoscope overcomes the low sound levels by digitally amplifying the body sounds. Digital stethoscopes convert the acoustic sound waves obtained through the chest piece into electrical signals which can then be amplified for optimal listening. These electronic signals can be further processed and digitalized to transmit to a personal computer or a laptop. The diagnostic power provided by digital stethoscope auscultation to a physician can assist in altering management in patient care.
Project ObjectivesStudy of PCG signals
Implementation of filters for pre processing of PCG signals
Design of Amplifiers for PCG signal
OUR FYP project is digital sethscope .digital stethoscope is able to convert an acoustic sound to electronic signals, which can be further amplified for optimal listening. These electronic signals can be further processed and digitalized to transmit to a personal computer or a laptop
Digital sethscope price is very high and there is no parameter define in their software to find the Accuracy so, we can decide to design the digital sethscope in very resonable price and define the parameter
In our project firstly we design pre-amplifier it can be used in to amplify the inital signal becuse the intial signal is very weak .Second step is to design the low pass filter to remove the high frequecies such as sound waves or other type of distortion.3rd step is to design the power amplifier it can amplify the signal upto 50X .and the last step is to show the graph in precise parameter to make the decision easier for the doctor
Benefits of the ProjectDigital stethoscopes have brought about a lot of benefits to the health industry.
1. record
2. Amplifying sounds
3. Noise reduction of surrounding noises
4. Accurate readings
5. Visual display
6. Telehealth
