A hearing detection device for self hearing-detection and fitting of hearing aids includes a hearing detection unit, a control unit and a hearing aid unit. An electronic device obtains a device serial number from the hearing detection device and adjusts a voice playing signals according to the device serial number when the hearing detection device is coupled to the electronic device. The control unit converts the voice playing signals into a detection signal and performs hearing detection for the user by the hearing detection unit when the control unit receives the voice playing signals. The user outputs a result of hearing detection to the control unit by operating an operation interface of the electronic device, and the control unit converts the result of hearing detection into a hearing data and outputs the hearing data to the hearing aid unit.一種可自我檢測及驗配聽力的聽力檢測裝置,包括:聽力檢測單元、控制單元及助聽單元。當聽力檢測裝置耦接電子裝置後,電子裝置由聽力檢測裝置獲取裝置序號,並依據裝置序號調整聲音播放訊號;當控制單元接收到聲音播放訊號時,控制單元轉換聲音播放訊號為檢測訊號,並供聽力檢測單元對使用者進行聽力檢測;使用者透過操作電子裝置的操作介面將聽力檢測結果輸出至控制單元,且控制單元將聽力檢測結果轉換為聽力資料,並輸出聽力資料至助聽單元。100‧‧‧聽力檢測系統10‧‧‧聽力檢測裝置12‧‧‧聽力檢測單元14‧‧‧控制單元16‧‧‧助聽單元20‧‧‧電子裝置30‧‧‧伺服器Sv‧‧‧聲音播放訊號Sd‧‧‧檢測訊號Sh‧‧‧聽力訊號Ih‧‧‧聽力資料
