We created a system that allows the visualization of sounds making it possible to visualize breath sounds. It allows real-time fast Fourier transformation of the sound signal and three dimensional (frequency-amplitude-time) rending of the results on a personal computer while processing two individual sound signals simultaneously. The frequency band of breath sound is located between 100 and 500 Hz. The system could be used to display bilateral breath sounds in pediatric patients. It could detect unilateral breath sound as a tracheal tube was advanced from the trachea to the bronchus. The results were equivalent to those obtained with conventional auscultation.

我们创造了一个系统，可以使声音可视化，从而使呼吸声音可视化成为可能。它允许声音信号的实时快速傅立叶变换和在个人计算机上的结果的三维(频率-幅度-时间)再现，同时处理两个单独的声音信号。呼吸声的频段在100至500赫兹之间。该系统可用于显示儿科患者的双侧呼吸音。当气管导管从气管推进到支气管处时，它可以检测到单侧呼吸声。结果与常规听诊结果相当。
