Abstract
Limiting the sound pressure level presented to the listener's ears by one or more headphones, using processing capabilities of a personal media device. Headphones, coupled to audio signals from a personal media device, include a sensor to measure the sound pressure level presented to the listener's ears, and provide that measure to the personal media device. The personal media device, optionally aided by one or more analog circuits, adjusts the audio signal so that the sound pressure level is maintained within a recommended range.
