INSPECTION SYSTEM AND INSPECTION METHOD

An inspection system includes two or more microphone units and an inspection controller. The two or more microphone units are disposed side by side in a vehicle. The inspection controller is configured to cause an inspection-target speaker to output an inspection sound, and determine, on the basis of a sound picked up by a main microphone unit and a sound picked up by one or more satellite microphone units, whether the inspection-target speaker passes or fails. The inspection-target speaker is any of one or more speakers mounted on the vehicle. The main microphone unit is one, of the microphone units, that is disposed at a position corresponding to a position of the inspection-target speaker. The one or more satellite microphone units are each one of the microphone units excluding the main microphone unit.
