In teaching disciplines such as acoustics, construction physics and mechanical engineering, students have to learn the basic principles of measuring systems and how signals are processed. To help them gain a sound working knowledge, it is useful to explain different measuring and analysis processes by demonstrating practical examples. This should be done by using tools that offer the highest possible degree of flexibility and parameterization. These for example allow students to visualize the influence of different sampling rates and filter functions while taking measurements.

Teaching and Learning with PAK

Different windowing and averaging scenarios and block durations can be flexibly varied with PAK software, which can clearly illustrate the differences in the time and frequency domain of analyses. Along with the standard FFT analyses, it is advisable to teach other methods, such as:

  • Psychoacoustic analyses;
  • Rotational speed-based analyses;
  • Transfer functions (for example from impact measurements); or even
  • Simple averaging methods.

In teaching these other methods, attention should be focused on the methodology, and as little time as possible should be invested in the renewed implementation of traditionally used algorithms or even graphic representation methods. A powerful and flexible tool such as the PAK software helps teaching institutions to do this.
