Abstract
A method of operating a media player includes playing back audio media. During the step of playing back audio media, a maximum volume parameter is refined for the playing back of the media by the media player. The refining is based at least in part on the playing back of audio media during a time period prior to executing the maximum volume refining step. After a period of time, the maximum volume refining step is repeated. The refining is configured to prevent/minimize harm to hearing of the media player user based, for example, on the actual volume of media playback and time/duration profiles provided by occupational safety and/or other organizations.
