According to a disclosed embodiment, an auscultatory training apparatus
includes a database of pre-recorded physiological sounds stored on a
computer for playing on a playback system. A user-friendly, graphical
user interface software program is stored on the computer for use with a
conventional computer mouse. The program allows a user to select one of
the pre-recorded 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. If employed by the user, the inverse model processes
the selected sound to cancel the distortions of the playback system so
that the sound is accurately reproduced in the playback system. The
program also permits the extraction of a specific sound component from a
pre-recorded sound so that only the extracted sound component is audible
during playback.
