1. An apparatus, adapted to be worn near an ear of a person, comprising:

  • at least one optical emitter configured to direct optical energy to a region of the ear;

    at least one optical detector configured to sense secondary optical energy emanating from the ear region;

    at least one footstep sensor configured to measure signals from footsteps of the person; and

    at least one signal processor configured to receive signals produced by the at least one optical detector and the at least one footstep sensor, wherein the at least one signal processor is configured to selectively remove interference caused by footstep signals from the signals produced by the at least one optical detector to produce at least one processed signal containing cleaner physiological information from the person, and wherein the at least one signal processor is configured to process signals produced by the at least one footstep sensor to produce at least one processed signal containing cleaner information about footsteps of the person.
