Abstract
In this thesis, it is examined how acoustic emissions produced by temperature changes in materials can be used to detect hidden structural fires. Experiments has been carried out with the aim of studying the possibilities of identifying the direction of the sound source in various wooden elements using contact microphones. The results shows that the method is valid in simpler wooden structures, but further processing of data is necessary for more complex wooden designs.

Further studies have been carried out in this thesis with regard to the rescue services need for new methods regarding construction fires. As current methods are not perfect, they view sound as a good supplementary detection system.
