Abstract

Audacity je besplatni računalni program za snimanje i obradu audio signala putem zvučne kartice. Jedna od mogućnosti njegove primjene je u nastavi fizike na različitim razinama. U ovom diplomskom radu detaljno su opisane glavne mogućnosti ovog programa s idejom kako bi se zvuk, pomoću raznih pokusa obrađenim na programu Audacity, mogao bolje i detaljnije objasniti učenicima srednjih i osnovnih škola.Pokusi koji su obrađeni u okviru diplomskog su: 1.) Određivanje razine zvuka raznih situacija u razredu; 2.) Mjerenje brzine zvuka; 3.) Udari; 4.) Rezonancija; 5.) Dopplerov efekt. Osnovna prednost leži u tome što za izvođenje pokusa nije nužna skupa eksperimentalna oprema, nego je najbitnije računalo opremljeno zvučnom karticom te instaliranim programom Audacity i mikrofon, što postoji u svakoj školi. S obradom gradiva zvuka pomoću pokusa obrađenim u Audacityiju mogla bi se podići razina zainteresiranosti učenika za fiziku uopće, što je i cilj ovog diplomskog rada.

Abstract (english)

Audacity is a free computer softwer, recorder and audio editor. One of the possibilities of its use is in the physics education on many different levels. In this thesis there will thoroughly be described main features of this program and how could sound, using various experiments processed on the program Audacity, be explained better to the students of secondary and primary schools.The experiments that will be processed are: 1.) Determination of the sound level of various situations in the classroom; 2.) Measuring speed of the sound; 3.) Beats; 4.) Resonance; 5.) Doppler effect. The main advantage in the performances of these experiments is that it doesn’t need expensive experimental equipment, but the most important is to have a computer equipped with a sound card and installed program Audacity and the microphone, which every school own. With processing the materials of the sound using experiments processed in Audacity could raise the level of interest of students in physics in general, which is the goal of this thesis.
