The invention discloses an electroencephalogram measuring device combining magneto-acoustic coupling and sound source localization and a monitoring method. The device comprises a power supply which is in charge of supplying power to an N pole electromagnet and an S pole electromagnet, and further comprises a teslameter which is used for detecting magnetic field intensity and a low-frequency acoustic detection array module which is used for detecting a sample acoustic signal, wherein a vibration isolation table and a sound insulating box which is arranged on the vibration isolation table are arranged between the N pole electromagnet and the S pole electromagnet; and a sample is arranged in the sound insulating box. The method comprises the following steps: insulating sound of a laboratory and making the sound insulating box; determining noise of an internal environment of the sound insulating box and saving the noise in a computer; judging whether the noise of the internal environment of the sound insulating box is lower than a preset laboratory noise threshold or not; applying a sound-conducting paste on the sample and keeping the sample in the sound insulating box, and fixing a low-frequency acoustic sensor array to the tested sample; electrifying the electromagnets; acquiring corresponding information on the basis of magneto-acoustic signals and saving the information in the computer; calculating positional information of electroencephalogram signals, so as to obtain a sound distribution image; and acquiring a final sound image. According to the device and the monitoring method provided by the invention, real-time precise localization of the electroencephalogram signals can be achieved by virtue of a plurality of sensors.
