1. A method of determining characteristics of tissue of the respiratory system in situ, said method including:

  • introducing an audible sound to the tissue at first position;

    detecting the sound at another position spaced from the first position after it has travelled through the tissue;

    calculating the velocity and attenuation of sound that has travelled through the tissue from the first position to another position; and

    correlating the velocity and attenuation of the detected sound to characteristics of the tissue of the respiratory system.
