Document Type and Number:
Japanese Patent JP2022059225
Kind Code:
A
Abstract:
To provide a method for estimating the generation source of abnormal noise with which the generation source of radiated sound from cavity portions in a cabin can be estimated with high accuracy.SOLUTION: A sound pressure visualization device 80 visualizing and displaying sound pressure measures abnormal noise in a cabin. When holes and gaps present in the cabin are taken as cavity portions, a control unit 90 acquires sound data related to abnormal sound from the cavity portions, of the abnormal sound measured by the sound pressure visualization device 80, and executes processing of estimating the generation source of the abnormal noise based on the acquired sound data.SELECTED DRAWING: Figure 1
