Sound image direction sense processing method and device

An embodiment of the present invention provides a sound image direction sense processing method and device. By means of a left ear channel signal, a right ear channel signal and a middle channel signal for obtaining a sound source, the middle channel is disposed on a sagging surface between the left ear channel and the right ear channel; according to the left ear channel signal, the right ear channel information and the middle channel signal, it is determined whether the location of the sound source is a front location, which is a location faced by the middle channel; when the sound source is the front location, at least one processing of the following is performed on the left ear channel signal and the right ear channel signal, respectively: enhancement processing of the front location, and weakening processing of the rear location, thereby enlarging the difference between the front direction sense and the rear direction sense of the sound image to further increase the accurate rate of determination of the location of the sound source.
