中文摘要
我们创建了一个允许声音可视化的系统,使呼吸声音可视化成为可能。它允许实时快速傅立叶变换的声音信号和三维(频率-幅度-时间)渲染的结果在个人计算机上,同时处理两个单独的声音信号。呼吸声的频带位于100和500 Hz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时,它可以检测到单侧呼吸音。结果与常规听诊结果相当。
英文摘要
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.
