1. Selective Filtering Ear Plug By Dr. Abdelhafid Bouhraoua Inventor

2. Noise is everywhere … Construction City Construction

3. Sleep is Needed Can’t Sleep ? Too much noise

4. Total Isolation Use Ear Plugs

5. Total Isolation Advantage – Sleep Well Inconvenient – Cannot hear important sounds Adhan Baby Cry Telephone ring Alarm Clock

6. What to use ? ?

7. Use Selective Filtering Ear Plugs

8. Selective Filtering Principle Filter All the noise except authorized noise

9. Principle Miniature Speaker Electronics + RF Antenna + Battery Common “Total Isolation” Ear Plug RF Antenna to transmit Recognized Sounds to Ear Plug DSP-based sound Analysis device Microphone to listen to environment
