A study on a sound fire extinguisher using special sound lens

Abstract

Sound fire extinguisher is developed based on principle of quenching fire by blocking inflow of oxygen with contacting vibration energy from low frequency sound under 100 Hz to fire and then, lowering its temperature. The first sound fire extinguisher made by a Federal Defence researcher was very huge and based on theory of initial principles, making it hard to be commercialized. Although next sound fire extinguisher developed by students of George Mason University was smaller than before, it was also at the basic stage with early theory. What is more, disturbance from the too long cable and inconvenience of having to carry all the tools were not effective to be commercialized. By improving these drawbacks, Sori Sound Engineering Research Institute (SSERI) of Soongsil University has developed new concept sound fire distinguisher. It concentrates sound through special sound lens and increases energy 10 times more to put out the fire. This study researches about reducing weight of sound fire extinguisher based on new concept special sound lens created by Sori Sound Engineering Research Institute of Soongsil University.
