Patent attributes
A mobile terminal and sound pressure control method using sound saturation sensing are disclosed. The mobile terminal has a target digital value of an adequate output sound pressure level at a maximum volume level. The sound pressure control method includes: determining a digital value corresponding to a maximum output sound pressure level of an externally sourced audio material, wherein the externally sourced audio material is being replayed for the first time at a preset gain at the maximum volume level; comparing the determined digital value with the target digital value; adjusting, if the determined digital value is not equal to the target digital value, the gain so that a digital value corresponding to the adjusted gain is equal to the target digital value; and storing the adjusted gain as a gain value associated with the maximum volume level for the externally sourced audio material.
