1. A method of assessing at least one bodily characteristic, comprising:
- introducing at least one audible sound to at least one first bodily location, the at least one audible sound comprising at least one known parameter and being sufficient to travel through at least a portion of the body to produce at least one responsive sound;
receiving the at least one responsive sound from at least one second bodily location;
determining at least two determined parameters associated with the at least one responsive sound, the at least two parameters comprising velocity and at least one other parameter selected from attenuation and/or frequency; and
assessing at least one characteristic of at least a portion of the body based on the at least one known parameter and the at least two determined parameters.

Abstract
The present invention relates to a method of determining at least one bodily characteristic or condition, such as that of an animal, such as a human, for example. According to an aspect of the invention, the method relates to determining at least one bodily characteristic of a lung or an airway, merely by way of example, by introducing at least one sound to at least one first bodily location, and recording at least one sound from at least one second bodily location. The present invention also relates to an apparatus capable of such determination.

8. An apparatus for use in assessing at least one bodily characteristic, comprising:
-
at least one transducer sufficient to provide at least one audible sound at at least one first bodily location;
at least one first detector sufficient to detect sound from at least one second bodily location and provide at least one first sound output;
at least one second detector sufficient to detect sound at at least one third bodily location and provide at least one second sound output;
at least one filter sufficient to remove very low frequency environmental noise from the at least one first sound output to provide at least one first filtered sound output and from the at least one second sound output to provide at least one second filtered sound output;
at least one amplifier sufficient to amplify the at least one first filtered sound output to provide at least one first amplified sound output and the at least one second filtered sound output to provide at least one second amplified sound output; and
at least one processor for processing the at least one first amplified sound output to provide at least one parameter associated with the at least one first sound output and the at least one second amplified sound output to provide at least two parameters associated with the at least one second sound output, the at least two parameters comprising a velocity and at least one other parameter selected from attenuation and/or frequency. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
