PURPOSE: A method for recording sound through ear is provided, which has a function to install a microphone together which inputs speech into an earphone. CONSTITUTION: Sound obtained by receiving his own voice by installing a micro phone(100) onto his ear is converted into a digital signal by a converter via a low pass filter(102) of 4kHz band through an amplifier(101). Then, it is processed with a sampling rate of about 11kHz using a processor(104) and then is processed by a D/A(Digital/Analog) converter, and then passes through a low pass filter(106) again, and then is processed by an amplifier(107). And the obtained voice is stored in a recording apparatus.
