| Summary: | The biological sounds emitted by the human body during its operation, such as the pulmonary, intestinal, articular and cardiac, provide an easy way to assess the physiology of an individual; however its detection, acquisition and processing is expensive due tothe high price of the equipment.In this project an economic alternative was implemented through the characterization of low-cost transdu-cers for the registration of bioacoustic signals; in this case, cardiac type. In this sense, stethoscope bells weredesigned and printed in 3D, adapted to the transducer as a means of amplification at low frequencies, in which the heart beat is found.System functionality was verified by performing heart beat measurements in a clinical setting. The results obtained were quantified and analyzed by algorithms, showing a better response in low frequency, with theuseofbellsasameansofamplificationintheacquisitionofcardiacsignals. |
