PURPOSE: A method for measuring a noise of a mobile communication terminal and a method for warning a noise using the same are provided to conveniently measure a noise level and protect the hearing ability of a mobile communication terminal user. CONSTITUTION: A mobile communication terminal measures a degree of an external noise flowed in through a microphone by using a sound pressure sensor(S1). A control unit of the mobile communication terminal compares the measured noise level with a set noise level stored in a memory(S2). If the measured noise level exceeds the set noise level, the control unit operates a timer(S3). The control unit measures noise levels periodically(S4). The control unit compares the measured noise levels with the set noise level(S5). If the measured noise levels do not exceed the set noise level, the control unit returns to a routine measuring the degree of the external noise according to an initially set period(S6). It is judged whether a timer count time exceeds a set reference time(S7). If so, the control unit outputs a warning sound through a speaker(S8).
