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.本数据集收录了从胸壁不同点位录制的肺部音频及其标注文件，另提供一份独立的合并式总标注文件。标注内容涵盖三项信息：一是音型标注，包含吸气相（Insipratory: I）、呼气相（Experiatory: E）、哮鸣音（Wheezes: W）、湿啰音（Crackles: C）与正常音（N:Normal）；二是专家确诊的病症类别，涵盖哮喘（Asthma）、慢性阻塞性肺疾病（COPD）、支气管疾病（BRON）、心力衰竭、肺纤维化等；三是音频录制的胸壁点位，包括后胸部（Posterior: P）、下部（Lower: L）、左侧（Left: L）、右侧（Right: R）、上部（UPPER: U）、前胸部（ANTERIOR: A）与中部（MIDDLE: M）。 音频文件名遵循如下编码规则：1. 滤波类型：B对应20-200Hz钟型（BELL）听诊器，Diaphragm对应100-500Hz膜型听诊器，Extended range对应50-500Hz宽量程听诊器；2. 患者编号：P1至P112。 压缩包"Audio Files.zip"内含.wav格式音频文件，而"Stethoscope Files.zip"则收录了从听诊器导入的原始录制数据。
