• Description:
  The purpose of this project was to develop an auscultatory system capable of training health care workers to identify components of respiratory sounds associated with lung disease. A LabVIEW based playback system accurately recreates respiratory sounds obtained using a previously described recording system [1]. Under ordinary conditions, the original sound is distorted by the amplifier, speaker and surroundings. The reconstruction tool modifies the signal delivered to the speaker in such a way as to reproduce the signal as it was originally generated by the patient. A graphical user interface displays the recorded time signal and time-frequency distribution. Complete respiratory sounds or selected components, such as a single wheeze, can then be played back accurately. Components of the signals are extracted by a time-varying filter, based on user graphical selections. This tool can serve as a user-friendly graphical program which accurately reproduces respiratory sounds for teaching purposes. [Description provided by NIOSH]
