Auscultatory Training System

This auscultatory training apparatus includes a database of prerecorded physiological sounds (e.g., lung, bowel, or heart sounds) stored on a computer for playback.  A user friendly, graphical interface software program is stored on the computer for use with a conventional computer mouse.  The program allows a user to select prerecorded sounds for playback.  In addition, the program is operable to generate an inverse model of the playback system in the form of a digital filter.  The inverse model processes the selected sound to cancel the distortions of the playback system so that the sound is accurately reproduced.  The program also permits the extraction of a specific sound component from a prerecorded sound so that only the extracted sound component is audible during playback.  As well as a teaching tool to instruct the user on various body sounds, this invention could have applications as a diagnostic screening tool and as a telemedicine tool.
