Abstract
Resistance to fracture is an essential feature of roofing tile quality. As with all ceramic products, fracture resistance is dependent on the homogeneity of the material as well as the type and distribution of defects. On striking a roofing tile, the sound emitted is also determined by homogeniety of the roofing tile material. Thus, the practised human ear can test tile defects by judging the sound mode on striking the roofing tile. IST GmbH (Munich, Germany) have successfully developed a reliable acoustics testing device, the SONOR 2, based on the successful simulation of human hearing ability. The construction, operation, and test results of this device are described in this paper. Finally, it is shown how the device can be integrated as an essential component of a quality assurance system.
