Acoustic Laboratory (FCE CTU) The pulse (acoustic emission – AE) method based on the analysis of data collected by accelerometers attached to samples excited by a defined acoustic signal is one of the suitable methods for monitoring physical changes in heritage objects caused by external or environmentally induced loads. Acoustic characterization of materials is also often required when historic buildings are being repurposed for modern use as music halls, theatres, etc. The Acoustic Laboratory provides the capacity and equipment both for AE testing as well as for determining acoustic properties of a wide range of construction materials/construction elements by means of reverberation chambers. Its main equipment includes audio and function generators, amplifiers, signal analysers, precise piezoelectric microphones and a system of reverberation chambers designed for measurements of acoustic parameters of small-sized building materials samples/construction elements.
