Method and system for analysis of body sounds
First Claim
1. A system for evaluation of a human disease associated with abnormal body sound production from body multiple organ systems, the system comprising a microphone device placed in contact with a patient'"'"'s body;
- means for generating and amplifying an analog sound signal received from said microphone device;
as frequency analyzer connected to said generating and amplifying means and including first means for separating the sound signal into various frequency bands in infrasonic and audible spectrums, second means for determining a sound amplitude in each frequency band, and means for digitizing the analog sound signal to obtain digital signals; and
a computer for receiving said digital signals from said frequency analyzer and performing an average wave form analysis of said signals so as to provide time averaged calculation of body sound data.

Abstract
A method and a system for evaluation of a human disease by recording body sounds for extended periods of time by a microphone placed in contact with the body of the patient and using computer processing of body sound data to provide frequency domain and time domain sound amplitudes. A computer reads out a converted measurement of a sound taken by the microphone and places the data on the computer data bus for further processing. The method and system provide a diagnostic information on diseases, such as certain diseases of the gastro-intestinal tract and the heart, which generate abnormal body sounds and provide assessment of patient progress during treatment of such disease entities.
