摘要

虽然心音图能最准确地显示心音和杂音，并能提供临床上有用的信息，但它作为诊断工具的使用现在相当少见。一个可能的原因是听诊结果没有被记录为声音，因此它们不能再听。配有手持式电子听诊器的多媒体个人电脑可用于记录和分析心音。通过仔细的硬件选择，可以实现60 dB以上的信号动态。

Multimedia personal computer based phonocardiography

Although the phonocardiogram presents heart sounds and murmurs most precisely and it can offer clinically useful information, its usage as diagnostic tool is nowadays quite uncommon. One possible reason can be that auscultation findings are not recorded as sounds, and so they cannot be listened to again. Multimedia personal computer equipped with a handheld electronic stethoscope can be used to register and analyse the heart sounds. Over 60 dB signal dynamics can be achieved with careful hardware selections.
