ADAPTIVE NOISE CONTROL SYSTEM AND ON-LINE FEEDBACK ROUTE MODELING AND ON-LINE SECONDARY ROUTE MODELING METHOD

摘要

PROBLEM TO BE SOLVED: To provide on-line feedback route modeling and on-line secondary route modeling active noise control system and method. SOLUTION: A feed-forward active noise control system 50 provided with a reference sensor 16, a secondary source 18, an error sensor 20 and an active noise control system controller 10 for generating anti-noise signals for attenuating noise signals supplied through a medium is provided. The feed-forward active noise control system 50 executes on-line feedback route modeling and on-line secondary route modeling.
