Abstract
Ovaj diplomski rad temeljen je na mjerenju apsorpcijskog koeficijenta prema standardu ISO 10534-2. Kroz prva četiri poglavlja opisuje se teoretska baza za dobivanje apsorpcijskog koeficijenta. Prvo poglavlje je uvodno poglavlje gdje se diplomski rad stavlja u širi kontekst. Drugo poglavlje opisuje detaljnu teorijsku razradu za bolje razumijevanje mjerenja. Treće poglavlje opisuje standard ISO 10543-2 na temelju kojega je napravljeno mjerenje. Četvrto poglavlje opisuje mjernu opremu od koje se detaljnije razrađuju mikrofoni preko kojih se skupljaju podaci i cijev konstruiranu za ovo mjerenje. Zadnja dva poglavlja odnose se na usporedbu rezultata mjerenja i zaključak. U poglavlju rezultata mjerenja nakon kratkog teorijskog razmatranja uspoređuju se različite konfiguracije uzoraka sandwich i PUR+ljepilo+staklena vlakna za amplitudu i fazu prijenosne funkcije te zvučni tlak na pozicijama mikrofona 1 i 3 te 1 i 2. Prikazan je detaljan postupak računanja apsorpcijskog koeficijenta prema standardu preko transfer funkcije izmjerene na dvije lokacije mikrofona.
Abstract (english)
This thesis for degree of Master of Science is based on the measurement of the absorption coefficient according to ISO 10534-2. The first four chapters describe the theoretical basis for obtaining the absorption coefficient. The first chapter is an introductory chapter where the thesis is placed in a general context. The second chapter describes a detailed theoretical elaboration for a better understanding of measurement. The third chapter describes the standard ISO 10543- 2 from which the measurement of this thesis was made. The fourth chapter describes the measuring equipment from which the microphones through which the data are collected are elaborated in more detail and whose construction of the tube for this measurement is described. The last two chapters deal with the comparison of measurement results and conclusion. The chapter of measurement results after a short theoretical consideration compares different samples of sandwich sample and PUR + glue + glass fibers sample for amplitude and phase of transfer function and sound pressure at microphone position 1 and 3 and 1 and 2. Detailed procedure of absorption coefficient calculation is described according to standards via the change of transfer function of two microphone locations.
