Abstract This work presents a smart acoustic diagnostic interface that captures and transmits cardiac and respiratory sounds with better clarity and mobility. The system uses a small condenser microphone to detect biological sounds. These sounds are amplified by a low-power operational amplifier and filtered through an optimized band-pass filter to eliminate background noise. A microcontroller with Bluetooth Low Energy (BLE) capability processes the digitized signal and wirelessly sends it to a receiver device like a smartphone or headset for real-time listening and analysis. A rechargeable lithium-ion battery powers the entire setup, ensuring it is lightweight and portable. Experimental evaluation indicates that the device maintains clear audio transmission, low latency, and stable connectivity, making it suitable for remote auscultation. This system allows healthcare professionals to monitor heart and lung activity without needing to be close to the patient, aiding telemedicine and digital health applications. The proposed design offers a cost-effective, compact, and energy-efficient alternative to traditional stethoscopes. It represents a practical advancement toward modernized and connected diagnostic healthcare.
