“…Employed for over two centuries, it remains indispensable in clinical practice. However, conventional acoustic stethoscopes have limitations, including low sensitivity to faint heart sounds [4] and susceptibility to ambient noise [5]. Moreover, they rely heavily on the clinician's experience for the interpretation of sounds, and subtle changes can easily be missed.…”

<p>This study introduces a cutting-edge digital stethoscope optimized for remote health monitoring. Integrating Micro-Electromechanical Systems (MEMS) microphones with Bluetooth Low Energy (BLE) 5, the device ensures high-fidelity, real-time audio transmission. It seamlessly connects to an Internet of Things (IoT) platform through an embedded system, highlighting its potential in remote healthcare scenarios, especially during global health emergencies. Advanced features encompass Active Noise Cancellation, extended battery life, and intricate internal sound filtration. Paired with a dedicated Android application, the stethoscope streamlines the capture, storage, and visualization of auscultation data. Crucially, its integration with Electronic Health Records (EHRs) and its capability to generate vast datasets can significantly advance diagnostic precision, leveraging Digital Signal Processing and Artificial Intelligence methodologies. </p>
