Abstract:
An active noise reduction device reduces noise in a space within a vehicle body. The active noise reduction device includes a first input unit, a signal processor, and an abnormality determiner. The first input unit acquires, from a first vibration detector fitted to the vehicle body, a first signal that indicates a magnitude of vibration in a specific part of the vehicle body. The signal processor generates a cancellation signal that is used to output a cancellation sound for reducing the noise, by using the first signal as a reference signal having a correlation with the noise. The abnormality determiner determines whether or not an abnormality is present in the specific part by using the first signal.

Claim (Index 5):
The active noise reduction device according to  claim 1 , further comprising:\n a second input unit acquiring a second signal from a second vibration detector fitted to the vehicle body, the second signal indicating a vibration in a part other than the specific part, wherein the abnormality determiner uses the first signal and the second signal to determine whether or not the abnormality is present in the specific part.
