Claim 14:
15. A method for minimizing the production of a set of audible artifacts while providing mid-air tactile sensation to a user with an ultrasonic tactile stimulation device, the method comprising:
activating a set of transducers onboard the ultrasonic tactile stimulation device, wherein activating the set of transducers produces:
a set of pressure waves having an ultrasonic frequency, thereby forming the mid-air tactile sensation;

receiving, at a set of microphones onboard the ultrasonic tactile stimulation device, a signal comprising audio information from the user, wherein a sampling frequency of each of the set of microphones is less than twice the ultrasonic frequency;
processing the audio information to minimize the set of audible artifacts, comprising:
blocking portions of the signal having the ultrasonic frequency from reception at the set of microphones, thereby preventing an aliased artifact of the set of audible artifacts from being created during sampling;
sampling the signal at the sampling frequency;
evaluating the sampled audio information with a trained machine learning model; and

transmitting the processed audio information to a set of speakers associated with a second user, the second user associated with a second ultrasonic tactile stimulation device.
