Description

For a current research project (CULA - Computerized Lung Sound Analysis) we developed a multichannel recording device, which enables simultaneous recording of lung sound at several positions on the posterior chest. It is an effective non-invasive tool to monitor the respiratory system.

Most lung diseases cause distinct adventitious lung sound, like wheezes and crackles. However, some lung diseases (e.g. pneumothorax) only result in an attenuation of the lung sounds around affected regions. By illustrating the spatial changes in energy intensity we could provide a simple diagnostic tool for physicians.
