Abstract
Methods and apparatus are provided for automatically adjusting, by an audio device, the SPL of its audio output. As described herein, the SPL is adjusted based on approximated noise in an ear canal of occluded ears as determined by an accelerometer measuring the user's motion. According to aspects, the audio device adjusts a tone of the signal by adjusting the SPL of a set of frequencies and also adjusts the overall gain of the full frequency spectrum of the audio signal. The tone may be adjusted more quickly as compared to the overall broadband gain.
