Apparatus and method for processing data between neighbors to prevent dispute over noise travelling between neighbors

An apparatus and method for processing data between neighbors are provided. The apparatus may include the first and second communication devices. The first communication device in a first space includes a first processor that receives and processes information on a state of a first neighbor from an input interface and transmits a resultant state of the first neighbor to a display unit. The second communication device, in a second space spatially separated from the first space, includes a communication unit that communicates data with the first communication device, and a display unit that simultaneously displays the resultant state of the first neighbor transmitted from the first communication device. The resultant state of the first neighbor represents a degree of tolerance by the first neighbor over noise travelling between floors. The present invention provides an apparatus and method for processing data between spatially apart neighbors in order to prevent neighborly dispute over noise travelling between floors commonly occurring in multi-unit dwellings such as apartments in a mutually considerate, communicative and friendly manner.
