20220417678 · 2022-12-29 ·

A processing device is interfaced with an auditory region of the brain of a subject that is responsible for auditory perception. The processing device receives signals associated with nerve impulses that are transmitted to the auditory region of the brain of the subject in response to sound collected by an ear of the subject. The processing device processes the received signals and generates at least one audio signal that is representative of the auditory perception, by the subject, of the sound collected by the ear. In certain embodiments, the processing device processes at least one audio signal that is representative of at least one sound to convert the at least one audio signal to a sequence of nerve impulses, and selectively provides the sequence of nerve impulses to the auditory region of the brain of the subject such that the subject audially perceives the at least one sound.
