Abstract
Digital auscultation technologies have advanced significantly in recent years; however, their adoption in low-resource and rural healthcare environments remains limited due to high cost and lack of accessibility. This study presents the design and development of an affordable digital stethoscope aimed at improving diagnostic reliability in underserved clinical settings. The proposed system integrates a low-cost microphone sensor, signal conditioning circuitry, and a microcontroller-based digital processing module to capture, amplify, and filter heart and lung sounds with enhanced clarity. Audio signals are transmitted to a smart device for real-time visualization and storage, enabling telemedicine support and remote clinical assessment. Experimental evaluation demonstrates that the device achieves comparable accuracy to conventional digital stethoscopes while maintaining a significantly lower cost. The results indicate that the proposed solution can strengthen primary healthcare delivery, support early diagnosis, and improve patient outcomes in resource-constrained regions.
