1. A method for simulating physiological sounds of a patient responsive to measurements from one or more sensors attached to the patient, the method comprising:

  • detecting a first portion in an acoustic signal corresponding to a physiological process of inspiration;

    detecting a second portion in the acoustic signal corresponding to a physiological process of expiration;

    generating a first sound corresponding to the inspiration process based on the detected first portion, wherein the first sound includes a first characteristic;

    generating a second sound corresponding to the expiration process based on the detected second portion, wherein the second sound includes a second characteristic that is different than the first characteristic of the first sound;

    mixing the first sound and the second sound with a noise sound to generate a simulated physiological sound; and

    output the simulated physiological sound corresponding to physiological sounds of respiration.
