1. A method for controlling a mask apparatus, the method comprising:
measuring a current pressure value with respect to a mask by using a pressure sensor;
comparing each of a preset atmospheric pressure maximum estimation and a preset atmospheric pressure minimum estimation to the current pressure value;
updating the atmospheric pressure maximum estimation and the atmospheric pressure minimum estimation according to the comparison result; and
controlling a voice output of a speaker based on a difference between the updated atmospheric pressure maximum estimation and the updated atmospheric pressure minimum estimation,
wherein the atmospheric pressure maximum estimation is changed or updated in real time according to a maximum pressure value among pressure values measured by the pressure sensor for a predetermined time, and
wherein the atmospheric pressure minimum estimation is changed or updated in real time according to a minimum pressure value among the pressure values measured by the pressure sensor for the predetermined time.
