AB  - Fire is a very important thing in human civilization. However, fire causes enormous damage to humans
by conflagration. Due to the development of society, the fire protection environment has changed and more
efficient fire protection technology is needed and sound fire extinguisher can be an alternative. Sound fire
extinguisher has the principle that the fire is turned off by using various phenomena caused by the resonance
of the sound component. Sound fire extinguisher can easily suppress the flame by supplying a sound
component appropriate to the combustion characteristics of the flame. In this study, a low frequency speaker
was used to supply different sound components to the candlelight and the resonance dispersion size of the
candlelight was measured. Through these experiments, we tried to identify a sound component that can be
easily turned off by candlelight. Experimental results show that although, the resonance is somewhat different
depending on the position of the candlelight, the candlelight is dispersed by resonance at frequencies of about
30, 70 and 100 Hz at most positions. It can be predicted that the candlelight can be easily turned off by
resonance at the frequency of harmonics based on about 30 Hz band.
