After the successful completion of this module, the students understand - the basics of vibroacoustics - the basics of modelling of civil engineering constructions - the effect of noise and vibrations to humans and are able to describe them - the basic aspects of signal processing as well as the composition and function of the measurement chain elements They can classify dynamic loads from different sources. The students can apply the practical methods of structural dynamics and vibroacoustic measurement techniques to practical problems and assess the results.
In this module basics of the application of structural dynamical and vibroacoustic calculations will be handled. Application examples are given by practical problems and models. Also, the practical operation of measurement tasks (experiment set up, accumulation of data analysis of time line) are handled theoretically and carried out practically. The thematic outline is as follows: - Evaluation of vibrations (Perception through humans, comfort criteria, human induced oscillation) - Excitation of structures by dynamic loads, e.g. machines or humans - Methods of oscillation reduction - Soil dynamics (Basics of wave propagation, Soil-Structure interaction, methods of oscillation reduction) - Sensors and tools (accelerometers, microphones and laser vibrometers) - Calibration, Checking, Measurement Uncertainty - Signal Processing and Measurement Techniques (measurement chain setup, practical aspects of time-frequency analysis, time and frequency range filter) - Experimental modal analysis - Measurements and their analysis
