Abstract
A mobile terminal includes a processor that is programmed to provide a user of the mobile terminal with a hearing test and to determine a set of coefficients. A microphone is configured to receive audio signals therethrough. A digital filter is programmed with the determined set of coefficients and is configured to process the audio signals and transmit the processed audio signals to an earphone.
Claims18
A method of operating a mobile terminal that has a pair of microphones associated therewith, comprising:
- 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.
A mobile terminal, comprising:
- a pair of microphones;
- a processor that is programmed to provide a user of the mobile terminal with a hearing test and to determine a first set of coefficients and to determine a second set of coefficients based on training audio signals received through the pair of microphones when the microphones are placed in a plurality of orientations;
- an earphone;
- and
- a digital filter that is programmed with the determined first and second set of coefficients and is configured to process the received audio signals and transmit the processed audio signals to the earphone.
A computer program product for operating a mobile terminal that has a pair of microphones associated therewith, comprising:
- a computer readable storage medium having computer readable program code embodied therein, the computer readable program code comprising:
- computer readable program code configured to provide a user of the mobile terminal with a hearing test;
- computer readable program code configured to determine a first set of coefficients for a digital filter based on the results of the hearing test;
- computer readable program code configured to place the pair of microphones in a plurality of orientations;
- computer readable program code configured to receive training audio signals through the pair of microphones in each of the plurality of orientations;
- and
- computer readable program code configured to determine a second set of coefficients for the digital filter based on the received training audio signals;
- computer readable program code configured to receive audio signals;
- computer readable program code configured to process the audio signals using the digital filter programmed with the determined first and second set of coefficients;
- and
- computer readable program code configured to transmit the processed audio signals to an earphone associated with the mobile terminal.
