Latest Patents

Hisashi Kihara holds a patent for an active vibration noise control device. This device is designed to cancel vibration noise by utilizing a speaker to generate a control sound. Specifically, the device includes an attenuating unit that reduces a control signal produced by an adaptive notch filter. This control signal is then provided to the speaker when the amplitude of the filter coefficient exceeds a certain threshold. This innovation allows for the suppression of continuous fluctuations in the filter coefficient during abnormal occurrences. Consequently, it effectively mitigates cyclic abnormal sounds and reduces vibration noise during such events. His patent is a testament to his expertise and dedication to improving noise control technologies.
