providing a user of the mobile terminal with a hearing test;
determining a first set of coefficients for a digital filter based on the results of the hearing test;
placing the pair of microphones in a plurality of orientations;
receiving training audio signals through the pair of microphones in each of the plurality of orientations; and
determining a second set of coefficients for the digital filter based on the received training audio signals;
receiving audio signals;
processing the audio signals using the digital filter programmed with the determined first and second set of coefficients; and
transmitting the processed audio signals to an earphone associated with the mobile terminal.
