1. A method of detecting rainout in a respiratory therapy system, the respiratory therapy system including a respiratory therapy device, a user interface coupled to the respiratory therapy device via a conduit, at least one microphone, and a control system, the method comprising:
generating, via the at least one microphone, first acoustic data representative of noise associated with the respiratory therapy system;
analyzing, via the control system, the first acoustic data to detect a presence of liquid in the respiratory therapy system;
transmitting, to the user of the respiratory therapy system, (i) a notification of the presence of the liquid in the respiratory therapy system and (ii) a recommendation for action to reduce or remove the liquid in the respiratory therapy system;
generating, via the at least one microphone, second acoustic data representative of noise associated with the respiratory therapy system;
analyzing, via the control system, the second acoustic data to determine an amount of the liquid remaining in the respiratory therapy system following the action; and
in response to determining that the amount of the liquid remaining in the respiratory therapy system is less than a threshold amount, transmitting to the user, a notification that the amount of liquid remaining in the respiratory therapy system is less than the threshold amount.
