    摘要： A gas monitoring apparatus according to the inventive concept includes a sound generator, a sound receiver, and a sound field signal processor. The sound generator continuously outputs a sound signal into a gas monitoring space. The sound receiver receives a sound signal reflected from the gas monitoring space. The sound field signal processor obtains sound field information on the received sound signal, calculates a sound field spectrum for the sound field information, uses a correlation between the calculated sound field spectrum and a reference sound field spectrum, and determines whether there are gas leak and mixing in the gas monitoring space, wherein the reference sound field spectrum is a sound field spectrum according to frequency measured in a case where a gas is not leaked in the gas monitoring space, and the sound signal is formed by a linear sum of sine waves that have a plurality of frequency components.
