To provide a method that highly accurately identifies a sound source of noise in the vicinity of tires when driving vehicles on road surfaces.SOLUTION: In a sound source surveying method in which noise generated in tires outside running vehicles are measured and a sound source of the noise is identified based on measurement data on the noise, the noise is measured by a noise measuring device attached to a non-revolving part vertically moving with the tire, it is detected by a detector attached to any part of a vehicle that the tire gets over a protrusion of the road surface, data when the tire gets over the protrusion of the road surface is excluded from the measurement data on the noise, and then the post-excluded data is used in identifying the sound source.SELECTED DRAWING: Figure 3
