To provide a technology capable of inhibiting a voice of a hands-free call from being heard by a person other than a caller within a movable body while suppressing the addition of components.SOLUTION: A controller 2 for an active noise canceler which outputs a canceling sound for canceling an air-conditioning sound generated by an air conditioner in a movable body includes: a detection section 211 which detects the start of a hands-free call in the movable body; and a setting change section 212 which, upon the detection of the start of the hands-free call, stops or suppresses the output of the canceling sound for canceling the air-conditioning sound in the vicinity of a seat different from a seat of a caller of the hands-free call.SELECTED DRAWING: Figure 1
【課題】部品の追加を抑えつつ、移動体内においてハンズフリー通話の音声が通話者以外の者に聞こえることを抑制できる技術を提供する。【解決手段】移動体の空調装置にて生じる空調音を打ち消す打消音を出力するアクティブノイズキャンセラ用の制御装置2は、前記移動体におけるハンズフリー通話の開始を検知する検知部211と、前記ハンズフリー通話の開始の検知により前記ハンズフリー通話の通話者の席とは異なる席の近傍における前記空調音を打ち消す前記打消音の出力を停止又は抑制させる設定変更部212と、を備える。【選択図】図1
