1. A system to determine a physiologic state of a subject, the system comprising:
(a) a wearable housing;
(b) one or more auscultation modules coupled to said wearable housing and comprising:
(i) one or more pressure sources configured to induce a pressure force onto one or more regions of a subject; and
(ii) one or more ultrasound transducers configured to receive one or more ultrasound signals from said subject and generated in response to said pressure force when said wearable housing is worn by said subject, wherein said one or more ultrasound transducers are spaced away from a skin of said subject by a distance; and
(c) one or more processors configured to process said one or more ultrasound signals received from said subject and form a measurement of one or more auditory signals from said subject, thereby determining said physiologic state of said subject.
