Feasibility study on using acoustic camera for acoustic imaging to detect air leaks in a structure

Air leaks in installed building elements may act as thermal or sound leaks into a closed space, e.g. room enclosed by the building elements. Such air leaks are traditionally identified by using thermal imaging or infrared imaging techniques. As the air leaks can also cause sound leakage, acoustic imaging may also aid in leak detection. Therefore the purpose of the study was to assess the feasibility of using an acoustic camera to identify air leakage areas. The tests were performed in the ‘Energy House’ at the University of Salford, Manchester which is a test house built inside a lab and provides controlled test environments. A window with a small opening and door installed in the living room were excited by airborne sound and analysed by the acoustic camera. The results show that the acoustic camera identifies air leaks in the window and door structure at high frequencies. At low frequencies, the reverberant environment affects the sound visualisation due to reflections from the walls. Results from the acoustic imaging are compared with the thermal imaging results. Further investigations will be carried out in the Energy House with more visualisation techniques.
