The electronic device 201 may combine the inverted third sound signal 1030 and the second sound signal 1020 . As the inverted third sound signal 1030 and the second sound signal 1020 are combined, a fourth sound signal 1045 for gas measurement may be output. The electronic device 201 may predict the concentration of the gas based on the fourth sound signal 1045 .

The electronic device 201 may invert the fifth sound signal 1050 or the sixth sound signal 1060 . For example, if it is assumed that the fifth sound signal 1050 is inverted, the electronic device 201 may obtain the seventh sound signal 1070 by inverting the fifth sound signal 1050 . The electronic device 201 may combine the inverted seventh sound signal 1070 and the sixth sound signal 1060 . As the inverted seventh sound signal 1070 and the sixth sound signal 1060 are combined, an eighth sound signal 1085 for gas measurement may be output. The electronic device 201 may predict the concentration of the gas based on the eighth sound signal 1085 . For example, if no sound signal is detected as in the eighth sound signal 1085 , the electronic device 201 may determine that gas does not exist.

The electronic device 201 may obtain a third sound signal by inverting one of the first sound signal and the second sound signal, for example, the first sound signal. The electronic device 201 may combine the inverted third sound signal and the second sound signal. As the inverted third sound signal and the second sound signal are combined, a fourth sound signal for the user's exhalation may be output.
