STANDING WAVE ON GUITAR STRING

U radu je opisano kako žičani glazbeni instrumenti proizvode zvuk. Najprije su uvedeni osnovni pojmovi valnog gibanja i akustike. Zatim je izveden model malih oscilacija napete žice te je dobivena valna jednadžba. Pojašnjena je osnovna ideja složenih valnih gibanja i Fourierove analize. U drugom dijelu govori se o glazbenim intervalima i ljestvicama. Konačno, u eksperimentalnom dijelu su korišteni Soundcard Scope te Overtone Analyzer.In this work it is described how string instruments produce sound. Firstly, general therms of wave motion and accoustic are introduced. Afterwards, model of small oscillations is presented and wave equation is derived. Basic idea of complex wave motion and Fourier analysis is explained. In second part are discussed ideas of music intervals and scales. Finally, Soundcard Scope and Overtone Analyzer are used in experimental section
