A simple bedside technique of heart sound simulation using hand and stethoscope is described. The technique utilizes tissue vibration and sound conduction with the usual air column of a stethoscope to reproduce auscultatory events accurately without the distortion that often accompanies electrical production of heart sounds.
本文描述了一种使用手和听诊器进行心音模拟的简单床边技术。该技术利用组织振动和声音传导以及听诊器通常的气柱，准确再现听诊事件，而不会产生通常伴随心音电产生的失真。
