'Acoustics' Toolbox for teaching (vor Ort)

Abstract:
In classical academic teaching, theory is taught in classroom lectures and deeper practical comprehension is to happen later during laboratory experiments. This separation is due to practical reasons, because setting up an experiment takes time and transport of measurement equipment to the classroom is difficult or inconvenient. In order to support the understanding of theoretical contents, it would be helpful to have experimental demonstrations in the classroom during a lecture and right before or after the theoretical input. In acoustics there is already a huge variety of powerful software, that might be used for experiments and their evaluation. However, from a teacher’s point of view, the complexity of most programs makes their application inefficient during the short duration of a lecture. For this reason, the “Acoustics” toolbox was developed and shared in MATLAB. It can be used for recording and analysis of analog voltage, sound and acceleration signals both in time and frequency domain. It is applicable for quick demonstrations during lectures or labs. In order to keep its operation simple, all functions and parameter inputs are visible without having to use hidden menus. It works both with onboard soundcards or external data acquisition devices with up to four channels.
