According to the features of the present invention, the present invention relates to a real-time interlayer noise removal system comprises: one or more sound input units to which identification numbers are respectively allocated according to installed locations, and which receive sound generated from the ceiling; a main server which includes a main DB for storing one or more reference waveform data respectively stored for each frequency of sound generated from the ceiling, one or more offset waveform data offsetting the sound corresponding to the reference waveform data, and location information according to the identification numbers of the sound input units, a sound analysis unit for analyzing sound received from the sound input units to generate waveform data, a sound detection unit for comparing the waveform data with pre-stored one or more reference waveform data to detect reference waveform data having a higher concordance rate, and a communication unit for receiving sound inputted from the sound input units and transmitting, to one or more sound generating units, offset waveform data corresponding to the reference waveform data detected by the sound detection unit; and the one or more sound generating units which include a sound converting unit for converting, into sound, offset waveform data transmitted from the communication unit and outputting the sound, and which are installed near each of the sound input units, and installed to generate sound towards the ceiling. Accordingly, the real-time interlayer noise removal system can receive sound through sound input units installed on the ceiling when an interlayer noise occurs, can compare the sound with pre-stored reference waveform data, and can output, through the sound generating units, offset waveform corresponding to the matched reference waveform data, thereby removing the interlayer noise.
