Fire is a particularly feared hazard. Therefore, a fire extinguisher is very important equipment. Unfortunately, existing fire extinguisher has some drawbacks such as using a chemical compound which is dangerous and it leaves a residue. Therefore, the need for a new fire extinguisher method is needed to overcome this problem. After various researches, it was found that sound waves can be used as an alternative method to extinguish flames. Acoustic pressure and air velocity produced from a speaker is the fundamental concept used to explain how sound waves put off flames. In this paper, we proposed a new method using the sound wave to extinguisher fire. Our method was using a speaker and a converging tube to focus the sound wave to overcome the fire energy and thus put the fire down. The aim is to develop a portable fire extinguisher to study and analyzes the effect of different frequency of a sound wave on flames. Experiments are conducted to find a suitable frequency range to extinguish the flame and to analyze the acoustic-flame interaction. Three different sources of flames were used with three different states of fuel (solid, liquid and gas). Using this method, a different set of experiments were conducted to find the range of frequencies within which fire can be extinguished and found that fire can be extinguished between 48 Hz to 60 Hz. Also, we found the optimum frequency as 53Hz. From the result of the experiment, the sound waves manage to extinguish all flames of different fuel types. We also found the applications of this extinguisher at Travancore Titanium Products (TTP) Ltd., Kerala, India. However, in both experiments the flame boundary used was relatively small as compared real fire accidents due to safety consideration. Nevertheless, this sound wave based fire suppression technology could be used to combat early stages of fire accidents.
