The occurrence and nature of cough sounds, especially those occurring in asthma in young children, is of considerable interest to workers in paediatrics and general practice. To facilitate our research into the characteristics of such sounds, we have developed a microcomputer-based analysis system, which we call COFF. In this paper we discuss the design and implementation of the system, emphasising its user-friendly, interactive features, and the manner in which it efficiently manages the large amounts of data that research into sounds incurs. We illustrate the operation of the system with examples of spectrograms computed from cough sounds recorded simultaneously at the mouth and through the chest wall.
咳嗽声音的出现及性质，尤其是在幼儿哮喘中出现的咳嗽声音，引起了儿科医生和全科医生的极大兴趣。为便于我们研究此类声音的特征，我们开发了一个基于微型计算机的分析系统，我们称之为COFF。在本文中，我们讨论了该系统的设计与实现，重点强调了其用户友好的交互式功能，以及它有效管理声音研究中产生的大量数据的方式。我们通过从口腔和胸壁同时记录的咳嗽声音计算出的声谱图示例来说明该系统的操作。
