AB  - Conflagration is a disaster caused by uncontrolled fire. The conflagration increases sharply as the
suppression slows down. Therefore, conflagration should suppression as fast as possible under all
circumstances. Sound fire extinguisher is being studied to maximize the efficiency of conflagration suppression.
The sound fire extinguisher has the principle that the sound component resonates with the flame to depress
the combustion reaction. In this study, we investigated the effect of the sound component of the sound fire
extinguisher on the combustion reaction depression by measuring the oxygen concentration change in the
candlelight experiment of the closed space. Combustion is a rapid oxidation phenomenon that occurs when a
substance comes into contact with oxygen and the amount of combustion is closely related to the amount of
oxygen. The influence of the sound component on the amount of combustion was confirmed by measuring the
amount of oxygen. As a result of the experiment in study, when the sound was supplied, the amount of
combustion decreased and the oxygen concentration in which the candlelight was turned off increased. This
confirms that the sound component of the sound fire extinguisher has an effect of depressing the combustion
reaction of the flame.
