Temperature and Frequency of a Nyltech Ukulele String

Abstract

A wooden ukulele with nyltech strings was plucked at temperatures ranging from -10°C to 67°C and the frequency was recorded. The thermal expansion and the Young’s Modulus of the ukulele string was measured over the same range of temperatures. A theoretical model of the frequency of oscillation of a stretched string as a function of thermal expansion and Young’s Modulus was developed. The frequency predicted by the model was compared to the recorded frequency values, supporting the validity of the theoretical model.
