Laennec于1816年发明了听诊器，并于1819年发表了一篇关于听诊的论文。然后，我们不得不等到20世纪50年代才观察到现代记录和信号处理设备和方法的发展，这使得在时间和频率场中客观地研究肺音成为可能。通气产生的气管支气管音起源于上呼吸道，这些声音的频率含量已经引起了广泛的研究，实变肺作为更有效的声音传导到胸壁（支气管呼吸杂音），气管支气管音与水泡肺音相比含有更高的频率成分。水疱性肺音的起源在近10年来逐渐清晰。它至少部分是局部产生的，深层的，可能是小叶内的。显然，需要进行进一步的研究，以阐明产生水疱性肺音、肺内气体的再分配或肺组织拉伸引起的振动的真正机制。所开发的设备已经用于监测重症监护患者的状态，迟早，实时分析和自动诊断将成为可能。
Laennec invented the stethoscope in 1816 and published a treatise on auscultation in 1819. We then had to wait until the 1950s to observe develop ment of modern devices and methods of recording and signal-processing, which allowed objective studies of lung sounds in time and frequency fields.Tracheobronchial sounds generated by ventilation originate in the upper airways, the frequency content of these sounds has led to extensive research, Consolidated lungs act as more efficient sound conductors to the chest wall (bronchial breathing murmur), Tracheobronchial sounds contain higher frequency components compared to vesicular lung sounds.The origin of vesicular lung sounds has been becoming progressively clear for about 10 yrs. It is at least partly produced locally, deep, and probably intralobular, Clearly, further studies need to be performed in order to elucidate the true mechanisms involved in generating vesicular lung sounds, the redistribution of intrapulmonary gas or vibrations caused by the stretching of lung tissue.The devices developed are already useful for monitoring the state of patients in intensive care, Sooner or later, real time analysis and automated diagnosis will become available.
