摘要
A leak from a pipeline can be detected accurately, even in an environment where noise due to moving sources of noise occurs. This leak detection device of one aspect of the present invention is provided with: a subtraction unit for subtracting noise from non-moving sources of noise from a first signal, on the basis of the first signal which is acquired from a sensor installed at a location at which it is possible to detect leak noise from a pipe, and a second signal which is acquired from a sensor installed at a location at which it is possible to detect ambient noise, and further subtracting noise from moving sources of noise; and a leak assessment unit for assessing whether a leak exists, on the basis of the result of subtracting the noise from non-moving sources of noise and the moving sources of noise from the first signal.
