Development and Comparison of Lung Sound Transducers

Master Thesis
Announcement date
11 Mar 2015
Research Areas


Auscultation is the act of listening to the sounds of internal organs. It is an effective non-invasive clinical tool to monitor the respiratory system. Therefor, the stethoscope is used for more than 200 years. The inherent inter-listener variability and the recent technical advances yield to an increased interest in computer-aided lung sound research.

In a current project (CULA - Computerized Lung Sound Analysis) a multichannel recording system is developed. An important task is the selection/development of the sensor. In lung sound research the sensors are generally designed by the investigators or adapted from related fields. Crucial requirements for the sensors are high sensitivity and robustness against air- and body-borne noise.
