TU Graz develops screening system for lung sound analysis

In a total of 16 channels, the recording device developed at TU Graz records the lung sounds during breathing. TU Graz By Susanne Eigner - A multi-channel recording device developed at TU Graz for pathological lung sounds and associated automatic lung sound analysis could support existing screening methods for early detection of, for example, Covid-19 infections. This now requires clinical data and interdisciplinary collaboration. They whistle, hiss and crackle. Our bodies constantly make sounds that (fortunately) are not always audible to the naked ear. The occurrence of certain noises or changes in normal sounds can be an indication of illness. Using the example of the lung, a research team at Graz University of Technology has been intensively engaged in noise recording and the development of computer-aided analysis methods as a supplement to medical diagnosis.
