SVTA-900
String vibration is a resonance phenomenon that is often seen in string instruments. To understand precisely the vibration of the strings and to measure the natural frequencies according to the length, thickness and tension of the strings, it is possible to compare them with the theoretical values and to study the relation between the mode shape, natural frequency and sound of strings. SVTA-900 is an experiment device designed for string vibration phenomena.
Detailed Description
