Abstract
A number of ear-worn hearing system devices are provided that each include a pair of electrodes to transmit time varying electrical signals therebetween when in contact with skin of a user's body. The devices each include a housing, a sound sensor, and processing circuitry included within the housing. The electrodes are coupled to the circuitry and are spaced apart from one another a distance sufficient to provide capacitance between the electrodes below a desired threshold. The electrodes are disposed along the housing for placement on locations of the user's body where skin contact is not likely to be disrupted by nominal body movements.
