1. An ear piece for use by an individual having an external auditory canal, comprising:
an earpiece housing configured for placement on, at, or within the external auditory canal of the individual;
a processor disposed within the ear piece housing;
a first microphone disposed at the earpiece housing, wherein the first microphone is outwardly facing at an outer portion of the earpiece housing to detect ambient environmental sound;
a second microphone disposed at the earpiece housing;
at least one speaker disposed within the earpiece housing at a position to direct sound towards the tympanic membrane of the individual;
wherein the ear piece is configured to detect ambient environmental sound proximate the external auditory canal of the individual using the first microphone, and producing a modified sound including the ambient environmental sound at the at least one speaker within the earpiece housing;
wherein the modified sound including the ambient environmental sound is based in part on a size and shape of the external auditory canal of the individual such that the modified sound reproduces the ambient environmental sound as if directly heard by the individual.
