1. An acoustic sensor configured to non-invasively detect acoustic vibrations associated with a medical patient, said acoustic vibrations indicative of one or more physiological parameters of the medical patient, said acoustic sensor comprising:

  • a sensor support;

    at least one sound sensing membrane supported by the sensor support and configured to detect acoustic vibrations associated with a medical patient and produce a membrane signal corresponding to the acoustic vibrations based at least in part on an attached state of the acoustic sensor; and

    a probe-off assembly supported by the sensor support, the probe-off assembly configured to produce a probe-off signal responsive to the attached state of the acoustic sensor and/or to a detached state of the acoustic sensor, wherein at least a portion of the sensor support is between a patient contact surface of the acoustic sensor and the probe-off assembly.
