Bluetooth Enabled Stethoscope

In noisy environments or for individuals with specific conditions, accurately capturing heart sounds can be challenging. This issue is further compounded by the inconvenience of physicians frequently removing earpieces. Additionally, the close face-to-face proximity required for auscultation (within 30-40 cm) increases the risk of cross-infection between patient and physician. Innovations such as wireless stethoscopes, digital transmission, and tele- auscultation can address these issues by enabling listening and reducing the need for close contact. The heart’s acoustic signals are captured, converted into electrical impulses via a microphone with a built-in preamplifier (MAX4466), amplified using a power amplifier (LM386), and transmitted in real-time to a receiving device where the signal is further amplified (PAM8403) and output to headphones, speakers. Its user-friendly interface and portability make it ideal for personal health monitoring and clinical diagnosis.
