Summary: | Heart disease becomes one of the most dangerous killers in the world. One of the
abnormalities of the heart is the heart murmur. This study aims to build a
phonocardiograph (PCG) -based smartphone that aims as a tool for early detection
of heart murmurs. In this research an android application is created that is able to
acquire voice signal data in the form of sound chart and then processed with
Discrete Fourier Transform (DFT) function to convert the heart sound signal into
frequency domain to make it easier to do the heart murmur detection. This android
application is built using Android Studio program on PC. To test the android
application that created, we compare DFT results between Android applications
that created with DFT in Matlab Software on PC. In testing on five subjects with
two people who have heart abnormalities and three normal people. From this test
can be summarized in outline, the DFT graph of the android application that
created is already able to represent heart sound signals and its murmur. On two
subjects who have heart abnormalities the murmur signals can be seen in the
application, whereas in three normal subjects, two of them are indicated normal
when viewed from the graphic results in the application, but at one other subject
we still seen a heart murmur signal. This may be due to differences in quality when
the data is influenced by the surrounding environment conditions and other noises. |
