听诊器已被临床医生广泛用于诊断和管理病人的疾病，它实际上已成为医学专业的象征。事实上，正如雷泽在《科学美国人》中指出的那样，莱内克发明的听诊器彻底改变了医学，使其从一门艺术变成了一门科学[1]。另一场革命正在进行，胸部听诊正在计算机化。推动这种计算机化的力量之一是，它提供了为非侵入性诊断提供改进的仪器的希望，即，不侵入人体或涉及辐射有害影响的工具。对听诊器在肺部听诊中的应用以及肺音计算机分析的发展进行了全面的综述[2]-[4]。还有一些最近的出版物报告了采用先进的信号处理技术来检测由肺音研究领域的一些小组开发的外来声音[6]，[7]。本次讨论将集中在临床上的重要应用，这种类型的调查，特别是多通道肺音分析的发展及其临床意义。
The stethoscope has been so widely used by clinicians in the diagnosis and management of patients' illnesses that it has virtually become a symbol of the medical profession. Indeed, as pointed out by Reiser in Scientific American, the invention of the stethoscope by Laennec revolutionized medicine, changing it from an art to a science [1]. Another revolution is now going on. Auscultation of the chest is now being computerized. One of the forces driving this computerization is that it offers the promise of providing improved instruments for noninvasive diagnosis, i.e., tools that do not invade the body or involve the harmful effects of radiation. Comprehensive reviews of the stethoscope's use in auscultation of the lung and of the development of computerized analysis of lung sounds have been presented [2]–[4]. There are also some more recent publications that report on employing advanced signal processing techniques for the detection of adventitious sounds that have been developed by a few groups in the field of lung sounds research [6], [7]. This discussion will focus on clinically important applications of this type of investigation and, in particular, on the development of multichannel lung sound analysis and its clinical importance.
