A dataset of lung sounds recorded from the chest wall using an electronic stethoscope
Annotated audio files (separate combined annotation file) of lung sounds as recorded from various vantage points of the chest wall. The annotation includes the sound type (Insipratory: I, Experiatory: E, Wheezes: W, Crackles: C , N:Normal), the diagnosis as decided by a specialist (Asthma, COPD, BRON, heart failure, lung fibrosis, etc.), and the location on the chest wall from which the recording was taken (Posterior: P Lower: L Left: L Right R, UPPER: U, ANTERIOR: A, MIDDLE: M). The audio file names are coded: 1. Filter type; B: BELL 20-200Hz, Diaphragm 100-500 Hz, Extended range 50-500 Hz. 2. Patient number: P1-P112. The zipped folder "Audio Files.zip" contains the .wav files, whereas "Stethoscope Files.zip" contains the original records imported from the stethoscope.
