Lung Acoustics Laboratory

Lung Acoustics Laboratory (LAL) is a place where researchers from different disciplines come and work together. Main areas of research conducted in LAL involve both hardware development for lung sound acquisition and diagnosis instrumentation and algorithm development for further processing of acquired lung sounds with the final aim of building an “intelligent stethoscope”. Some of the current topics in LAL are online processing and classification of respiratory sounds using digital signal processors, multi-resolution analysis of respiratory sounds, system development for multi-channel acquisition of respiratory sounds and modeling air flow-lung sound relationship.
