1. A system for minimizing the production of a set of audible artifacts while providing mid-air ultrasonic tactile sensation to a user, the system comprising:
a tactile stimulation device, wherein the tactile stimulation device provides the mid-air ultrasonic tactile sensation to the user, comprising:
a housing defining an internal cavity and a superior surface, wherein the superior surface defines a first set of apertures having diameters with an average 1st diameter value;
a set of transducers arranged within the housing and configured to produce ultrasonic pressure waves, the mid-air ultrasonic tactile sensation comprising the ultrasonic pressure waves, wherein the first set of apertures is configured to enable transmission of the ultrasonic pressure waves through the superior surface;
a set of microphones arranged within the housing, wherein each of the set of microphones defines an input port configured to record a signal comprising audio from the user; and
a set of ultrasonic input barriers arranged proximal to the set of input ports, wherein each of the set of ultrasonic input barriers defines a broad surface, the broad surface defining a second set of apertures having diameters with an average 2nd diameter value, wherein the second set of apertures is configured to block detection of a frequency associated with the ultrasonic pressure waves in the signal received at the set of microphones.
