Course Overview

In the industry today there is a large demand for staff with good knowledge in technics of measurement applicable to solve sound and vibration problems. The involved mix of knowledge from acoustics, mechanics and signal analysis in this technics of measurement is a difficulty. This course and its continuation courses aim to provide detailed knowledge concerning the application of signal analysis for measurements of sound and vibration. The course treats; fundamental structural dynamics, sensor technique for sound and vibration measurements, DAT-tape recorders for data acquisition, the FFT-analyser's multitude of applications within the area, computer based systems for data acquisition and frequency analysis. Methods concerning analysis of rotating machines are also discussed in detail. In this course the theoretical knowledge acquired in previous signal processing courses are applied to examples from industrial applications of the technics.
