Abstract
A system and method includes an audio device, such as an earbud or headphones, that includes one or more loudspeakers for outputting audio. The audio device further in includes one or more microphones that are positioned near an ear of a user. An acoustic barrier may be formed between a surface of the device and the ear of the user; properties of this barrier may, however, vary from user to user. The system determines these properties on a per-user basis and compensates for any differences therein.
