Technical Examples

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.
