Abstract:V diplomskem delu študiramo fizikalne osnove delovanja klarineta in flavte. Izvedemo eksperiment, pri katerem izmerimo zvočne spektre treh različnih glasbenih tonov teh dveh glasbil. Pri obravnavi klarineta izmerimo zvočne spektre za glasbene tone D1, Gis in D pri obravnavi flavte pa zvočne spektre za glasbene tone C2, G1 in C1. Pri analizi izmerjenih podatkov poskušamo nastanek tonov pri klarinetu in flavti pojasniti z nastankom stoječega zvočnega valovanja v trupu glasbila. Flavto obravnavamo kot odprto ravno cev, klarinet pa kot poldprto ravno cev [1]. V obeh primerih analiziramo ojačitev sodih in lihih višjih harmoničnih frekvenc izbranih tonov v trupu glasbil. Analiza zvočnih spektrov izbranih tonov flavte kaže, da smemo flavto v zelo dobrem približku obravnavati kot ravno odprto cev, saj se izmerjene osnovne kakor tudi višje sode in lihe harmonične frekvence tonov dobro ujemajo s teoretično napovedanimi frekvencami preprostega modela stoječega valovanja v odprti cevi. Rezultati eksperimenta pokažejo, da so v glasbenih tonih klarineta, zraven lihih, prisotne tudi sode višje frekvence osnovnih glasbenih tonov, česar s preprostim fizikalnim modelom stoječega zvočnega valovanja v poldprti ravni cevi ni mogoče pojasniti. Z eksperimentom podrobneje preučimo, v katerih delih trupa klarineta se ojačujejo lihi in sodi višji harmoniki. Eksperiment pokaže, da se sodi višji harmoniki ojačajo v ustniku, sodčku in odmevniku oz. lijaku klarineta. Ti deli klarineta niso ravne cevi, temveč so koničaste ali sodčaste oblike.
Keywords:Klarinet, prečna flavta, zvok, zvočni spekter, stoječe zvočno valovanje v ravni cevi.

Title:Sound spectrum analysis of clarinet and flute notes
Abstract:This diploma thesis deals with the basic physics of a clarinet and a flute. We perform the experiment in which we measure sound spectra of three different musical tones of the clarinet and the flute. When dealing with the clarinet, we measure the sound spectra of tones D1, G# and D, and for the flute we measure the sound spectra for tones C2, G1 and C1. With the analysis of experimental data we try to explain the generation of tones in the clarinet and the flute by considering simple theoretical models of standing sound waves inside the straight open or half-open tube. The flute is considered as a straight open tube and the clarinet as a straight half-open tube. In both cases, we analyse the amplification of even and odd higher harmonic frequencies of chosen tones inside the body of the instruments. The analysis of sound spectra of chosen tones generated by the flute reveals that the flute can be in a good approximation considered as a straight open tube. In this case, fundamental as well as even and odd higher harmonic frequencies predicted by the model describing standing sound waves in straight open tube are very close to the measured ones. The results of the experiment reveal that not only odd, but also even higher frequencies of fundamental musical tones are present among the clarinet’s musical tones. This cannot be explained with a simple physical model of standing sound waves inside a straight half-open tube. For this reason we perform an additional experiment, which enables us to study in which parts of the clarinet body the odd and even higher harmonics are amplified. The experiment reveals that even higher harmonics are amplified within the mouthpiece, barrel, and the bell of the clarinet.
Keywords:Clarinet, side-blown flute, sound, sound spectrum, standing sound waves in a straight tube.
