1. A wearable device comprising:
a support structure;
an audio module rotatably coupled to the support structure, the audio module comprising a parametric array of speakers configured to direct audio waves in a direction corresponding to a rotational orientation of the audio module relative to the support structure; and
a processor configured to:
with the parametric array of speakers, provide a first audio output;
from an external device, receive information relating to detection of the first audio output;
based on the information, determine a calibration factor;
based on the calibration factor, output a command; and
with the parametric array of speakers, provide a second audio output.
