Sensor pair for detecting changes within a human ear and producing a signal corresponding to thought, movement, biological function and/or speech

A detection system, comprising:

• a housing positionable with respect to an ear of a person;
• a first microphone disposed with respect to the housing for insertion into the ear of a person, the microphone operable to detect a change in air pressure within the ear while the person makes an initiating action and to produce an electrical signal corresponding to the internally detected change in air pressure;
• a second microphone disposed with respect ot the housing and located adjacent to the ear and operable to detect a chnage in air pressure external to the ear of the person and to produce an elctrical signal corresponding to the externally detected change in air pressure;
• and
• processing circuitry that executes logic to compare a signal strength difference between the electrical signal corresponding to the internally detected change in air pressure and the electrical signal corresponding to the externally detected change in air pressure to distinguish an initiating action component of each signal from an external source component of each signal and the processing circuitry coupled to the microphone for processing the processing the processes the elctrial signals to produce an output signal corresponding to the initiating action.
