Publication number: 20180211647Abstract: 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.Type: ApplicationFiled: January 9, 2018Publication date: July 26, 2018Inventor: MITSUHIRO TANI
