1. A method for outputting an adjusted audio signal by a wearable audio device, the method comprising:
outputting an audio signal;
continuously detecting ambient noise in the vicinity of the audio device;
determining the absolute value of the difference between a sound pressure level (SPL) of the audio signal and the SPL of the ambient noise is greater than a first SPL threshold amount;
automatically adjusting the SPL of the audio signal by boosting SPLs for both lower frequencies and higher frequencies of the audio signal based on the detected ambient noise, wherein the SPL is boosted more for the lower frequencies of the audio signal as compared to the higher frequencies of the audio signal, the SPL boosts for both the lower frequencies and the higher frequencies of the audio signal are dependent upon the detected ambient noise, and wherein the dependency varies among the lower frequencies and the higher frequencies; and
outputting the adjusted audio signal.
