Abstract: Disclosed are a method and a system for monitoring a fire based on a detection of sound field variation. The system for monitoring a fire based on a detection of sound field variation includes: a sound generator outputting a sound wave within a defined space according to input voltage; a sound receiver receiving the sound wave within the defined space and obtaining a sound pressure from the received sound wave; and a fire monitor using a sound transfer function representing a ratio of the sound pressure obtained by the sound receiver to input voltage of the sound generator in a preparation mode to calculate reference sound pressure information, using the sound transfer function in a monitoring mode to calculate current sound pressure information, and comparing the reference sound pressure information with the current sound pressure information to determine whether a fire occurs.

KSP Keywords: Fire monitor, Input voltage, Monitoring mode, Monitoring system, Sound field, Sound pressure, Sound transfer function, Sound wave, fire monitoring, transfer function(DTF)
