3. Problem statement : Need statement EE497 Bluetooth Stethoscope| Hessa Alshammri| Fatemah Alsaeedi| Haya Alnajdi 2 5/1/2019 1.The University of Geneva research team carried out tests for bacteria on the stethoscope and they found that the tube of the stethoscope carried more bacteria than the back of the doctors' hands. 2. Normal stethoscopes have heavy weight due to the tube connected (90- 180 grams). 3.The traditional stethoscopes have poor quality sounds and its effected by external factors which cause fail in diagnosis. 4.Based on survey, 96% of medical students suffers from the time- consuming searching of the (S1,S2) waves.

4. Objectives: EE497 Bluetooth Stethoscope| Hessa Alshammri| Fatemah Alsaeedi| Haya Alnajdi 3 5/1/2019 1.The system that we are designing will be able to hear the internal sounds of human body wirelessly using FM module. 2.The design aim is to diagnosis the diseases based on the rate of heart pulses. 3.The device will have a high-quality sounds by applying amplifiers. 4.The system should reduce the time searching of (S1,S2) waves.
