A plurality of reference signal detectors are placed respectively on right and left knuckles for respectively supporting right and left wheels. A vibration generator and an error signal detector are placed on a vehicle component part. A controller performs respective adaptive controls based on each of reference signals and an error signal so as to reduce the error signal, and controls the vibration generator based on a sum of respective output values of the adaptive controls."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Active noise cancellation apparatus","description":"Provided is an active noise cancellation apparatus capable of reliably reducing road noise by reducing vibration of a vehicle component part which generates road noise by using a vibration generator.
