Abstract
Methods and systems are provided for controlling bone conduction, in which a bone conduction element may be used to output acoustic signals when it is in contact with a user. A bone conduction sensor may also be made in contact with the user, and used to obtain feedback relating to the outputting of the acoustic signals via the bone conduction element. The outputting of the acoustic signals may then be adaptively controlled based on processing of the feedback. The adaptive controlling may comprise adjusting components and/or functions related to or used in the outputting of the acoustic signals. For example, the adaptive controlling may comprise adjusting gain, frequency response, and/or equalization associated with a drive amplifier driving the bone conduction element.
