Abstract
A system may include at least one audio transducer and a controller. The controller may generate at least one actuation signal. The at least one actuation signal may drive the at least one audio transducer such that the at least one audio transducer generates evanescent wave audio signals in proximity to a wearer's ear. The evanescent wave audio signals may decay in strength with distance from the at least one audio transducer. Various other apparatuses, systems, and methods are also disclosed.
