PURPOSE: A method for controlling a sound generator using human body-detecting sensor is provided to accurately set up a human body sensing time maximally according to a current state of a human body sensor in order to rapidly detect whether or not a user leaves a bathroom. CONSTITUTION: A server calculates a maximum human body sensing time of a sound generator(S300). When a human body sensing sensor senses a human body, a controller generates a sound signal by controlling the sound generator(S302,S304). The human body time is transmitted to a server(S306). When the human body is sensed within a human body maximum time, the human body sensing time is transferred to the server(S312,S316). Unless the human body is not detected within the maximum human body sensing time, the controller judges that the user leaves the bathroom(S318).
