Implementation of DSK TMS320C6416T Module in Modified Stethoscope for Lung Sound Detection

Lung sound disorder can be one of the signs that indicate the human respiratory problems. The conventional stethoscope can be used to determine the imperfection of the lung; however, it only depends on the ability of hearing. When someone's has problem of hearing, they cannot use this device. In addition, the sound of the conventional stethoscope sometimes cannot be heard clearly. This paper proposed a digital stethoscope that can be visualized. This research focuses on the ability of the system to transfer the signal sound into digital display that can be monitored in mobile phone. In this research, the recorded data of lung sound is stored in the PC using the 'record sound' program. The data was then analyzed using the waveform graph time-domain, FFT Power Spectrum, STFT Spectrogram and Wavelet Scalogram. For the communication between DSP TMS320C6416T and LabView 2012, a LabView 8.6 is used. In this research, the authors also use NodeMCU ESP826 as the Access Point of the communication. On the other hand, for generating the communication between the LabView and NodeMCU, the author used VISA (Virtual Instrument Software Architecture) of LabView 2012. From experiment to 6 patients, it can be found that the proposed device can run well and can visualize the normal lung with the frequency of 300 Hz -600 Hz.

“…It is true that lung sounds can be mixed with other sounds, especially the sound of the heartbeat, as the heart and lungs are located in close proximity to each other within the chest cavity. This is why healthcare professionals often need to carefully distinguish between lung sounds and heart sounds to accurately assess the health of these organs [25].…”

This study aims to develop a tool that can assist nurses in examining patients by displaying sounds and signals on a TFT LCD screen. This tool uses the MAX 9814 sound sensor, which converts sound into an electrical signal. This sensor will generate a voltage when the diaphragm inside it moves back and forth. To design this tool, researchers used a series of high pass filters and low pass filters with a cut-off frequency of 333 Hz - 714 kHz. During testing of this tool using the MAX 9814 sensor mounted on a stethoscope, the signal appears stable on the TFT LCD screen and sound can be played properly. However, if the placement of the stethoscope is not correct during the examination, this can also affect the signal and sound produced. This tool should not produce a clear and loud sound when checking, because if this happens, the inspection cannot be carried out optimally. This research also produces a signal shape that is almost similar to the signal on the phantom. It is important to note that the MAX 9814 can work optimally if it is not exposed to environmental noise. Therefore, if this equipment is used in a noisy environment, the signal and sound produced may be disturbed by environmental noise. This research was conducted with the aim of making it easier for doctors and nurses to carry out portable examinations, as well as to monitor signals and sounds easily.
