To provide a wireless terminal, a wireless system, and a wireless communication method that can manage terminal information leakage even in a more diverse radio wave environment.SOLUTION: A wireless terminal according to an embodiment includes an acoustic detection unit that detects a surrounding sound wave and acquires a detection signal, a signal processing unit that analyzes the detection signal and obtains acoustic information including one or more of a frequency spectrum and a signal period of the detection signal, and a first command definition unit that stores a control content for controlling the wireless terminal and a parameter of an acoustic signal corresponding to the control content. The wireless terminal includes a comparison determination unit that determines whether the acoustic information includes a feature point of the parameter of the acoustic signal stored in the first command definition unit, and a control unit that executes a control content corresponding to the parameter of the acoustic signal included in the acoustic information when the acoustic information includes the parameter of the acoustic signal stored in the first command definition unit as a result of the determination by the comparison determination unit.SELECTED DRAWING: Figure 2 【課題】より多様な電波環境においても端末の情報漏洩管理を行うことのできる無線端末、無線システムおよび無線通信方法を提供する。【解決手段】実施形態の無線端末は、周囲の音波を検出して検出信号を取得する音響検出部と、検出信号を解析して該検出信号の周波数スペクトルおよび信号周期のうち一以上を含む音響情報を取得する信号処理部と、無線端末を制御する制御内容および該制御内容に対応する音響信号のパラメータを記憶する第１の指令定義部とを備えている。そして、音響情報が、第１の指令定義部に記憶された音響信号のパラメータの特徴点を含むか否かを判定する比較判定部と、比較判定部の判定の結果、音響情報が前記第１の指令定義部に記憶された音響信号のパラメータを含む場合、音響情報に含まれる音響信号のパラメータに対応する制御内容を実行する制御部とを備えている。【選択図】図２
