Abstract
In detecting abnormal sound of a test object such as a vehicle immediately after completion of vehicle assembly, a reference sound data is recorded as reference data having phase and amplitude in each of multiple frequency bands reference sounds of types not previously recorded as abnormal sounds in the test object similar to the test object, test sound data is acquired which has phase and amplitude in the multiple frequency bands from test sounds generated by the test object. And sound feature data is acquires by comparing the test sound data with reference sound data in frequency bands the same as the multiple frequency bands and by changing amplitude of the test sound data based on amplitude of the reference sound data while maintaining phase of the test sound data, and abnormal sound is detected based on the acquired sound feature data.
