Abstract
An apparatus and method for diagnosing a microphone of a vehicle reduce an interior noise by applying an active road surface noise reduction method, learn sounds collected using a plurality of microphones to generate a simulated signal for a specific microphone, and detect a failure of the specific microphone by comparing the simulated signal with an actually measured sound of the specific microphone so that noise reduction efficiency can be improved by distinguishing a noise from an interior sound, a failed microphone can be accurately detected using the sounds of the plurality of microphones, the spread of an unnecessary noise can be prevented by diagnosing a failure of the specific microphone, and a more comfortable and stable interior environment can be provided to occupants.
