1. A bone conduction sensor for placement in an external auditory canal comprising:

  • a bone sensing element having a contoured surface adapted to fit against a wall of the external auditory canal increasing the surface area contact between the sensing element and the wall of the external auditory canal;

    at least one contact sensor adjacent the bone sensing element for determining contact between the bone sensing element and the external auditory canal; and

    a circuit portion electrically connected to the sensing element and the at least one contact sensor for determining whether the bone sensing element is in proper position and compensating for the position of the bone sensing element when not in proper position.
