25. Tradition Meets Technology: Acoustical Analysis of a Kazakh Dombra with Smartphones

Author

Kasper, Lutz and Vogt, Patrik

Abstract

The aim of this paper is to provide physics teachers and physics students with interdisciplinary cultural and scientific related content. The "dombra" is on the one hand a cultural symbol of Kazakhstan with a long tradition. On the other hand, the dombra as a musical instrument is an object of interest in acoustics. The topic can lead to deeper insights into theory of musical instruments and acoustics and to positive motivational effects as well. The idea of this article originated in a guest lecture in physics at Taraz State Pedagogical University (Kazakhstan), where one of the authors introduced physics teacher students to "New Technologies in Physics Education." This course was about good practice examples of integration of mobile devices and their built-in sensors in physics classes. An overview of this innovative educational field is given in Ref. 1. There is a wide range of smartphone-enhanced experiments, from simple hands-on experiments to complex digital data collection and modeling tasks in particular in the field of acoustics.

38. Determining the Speed of Sound in Different Gases with a Dog Whistle

Author

Vogt, Patrik, Kasper, Lutz, and Radler, Matthias

Abstract

Various experiments on vibrating gas columns and on frequency measurements with glasses and pipes have been presented in recent years in the "iPhysicsLabs" column. The determination of the sound velocity in different gases by measuring the sound running time has also already been proposed in an earlier paper. This article now adds another experiment to this series. Just by using a commercially available whistle (e.g., dog whistle, bobby whistle, or shrill whistle) and a smartphone with a spectroscope app, the speed of sound in various gases can be estimated. This experiment's chief merits are the straightforward experimental setup, the consumption of only small amounts of gas, the high measurement accuracy, and especially the simple theoretical background.
