十九世纪初期,La(?)nnec 首先提出肺泡呼吸音与‘罗音’(r(?)le)的概念,给肺音奠定了基础。以后,Latham 又提出干性音(Dry-sounds 及湿性音(Moist sounds)等词,认为干性音是指持续性乐音,湿性音是指间断性短的爆裂性噪音。此后,罗音(r(?)le)、干性罗音(Dry r(?)le)、湿性罗音(Moist r(?)le)、干罗音(Rhonchi)哮鸣音(wheezing)等词用法非常混乱,亦无明确定义。1957年,Roberton 及Coope 提出附加肺音分成两组:持续性音称哮鸣音、间断性音称爆裂音(Cra-ckling)。1973年,John Macleod 把附加音分为干罗音(Rhonchi)、捻发音(Crepit-ations)及胸膜音(Pleural sounds)。1978
In the early nineteenth century, Lañón néc first proposed the concept of alveolar breath sounds and ronin (r), laying the foundation for lung sounds. Later, Latham proposed the words “Dry-sounds” and “Moist sounds”, which refer to dry sounds as “persistent tones” and “wet tones” as intermittent short bursts. (?) le), Dry r?

In 1957, Roberton and Coope proposed additional lung sounds divided into two groups: persistent vocal wheeze, intermittent sound crackles (Cra-ckling). In 1973, John Macleod additional notes into dry Luo Rhonchi, Crepit-ations, and Pleural sounds.
