The invention relates to a noise measuring device, method and system. The device comprises a first reference positioning plate, a second reference positioning plate, an ultrasonic ranging positioner, main control equipment, a noise sensor support and a noise sensor. The method comprises the following steps: a master control device determines the ground clearance of a device to be tested and the reference distance from the device to a reference positioning plate; setting the terrain clearance of the to-be-tested equipment and the position of the reference positioning plate; the main control equipment determines a target position of a noise sensor arrangement measuring point; measuring points are arranged for any noise sensor, a first X-axis coordinate, a first Y-axis coordinate and a first Z-axis coordinate are obtained, and the position of a sensor support and the position of a base on the sensor support are adjusted; the first X-axis coordinate, the first Y-axis coordinate and the first Z-axis coordinate are
