Abstract
Namještaj za odlaganje okružuje čovjeka u svakodnevnom životu, stoga razvoj i poznavanje akustičnih svojstava namještaja pridonosi spoznajom o akustici prostora. Akustične ploče koriste se kao dio namještaja u uredskim prostorima, knjižnicama, hotelima, predavaonicama te svugdje gdje je potrebno prigušiti neželjeni zvuk i smanjiti odjek u prostoriji. Masivno drvo i neki kompoziti na bazi drva mogu doći u obzir kao akustični materijali. U ovom radu, pomoću novog uređaja za mjerenje, eksperimentalno će se odrediti koeficijent apsorpcije zvuka za različite vrste drva i pločastih materijala te uvidjeti kakve su njihove akustične osobine. Kao apsorber zvuka koristiti će se mineralna (kamena) vuna različitih debljina. Rezultati ispitivanja pokazali su da kod ispitivanja materijala na visokim frekvencijama postoji neznatna razlika u apsorpciji zvuka, pločasti materijali postižu lošije rezultate u odnosu na masivno drvo, a uzorak jelovine dodavanjem apsorbera imao je bolje rezultate u odnosu na uzorak hrastovine i bukovine.
Abstract (english)
Storage furniture surrounds people in everyday life, therefore the development and knowledge of the acoustic properties of furniture contributes to knowledge about the acoustics of the space. Acoustic panels are used as part of the furniture in office spaces, libraries, hotels, lecture halls and everywhere else where it is necessary to dampen unwanted sound and reduce echo in the room. Solid wood and some wood-based composites can be considered as acoustic materials. In this work, using a new measuring device, the sound absorption coefficient for different types of wood and panel materials will be determined experimentally, and their acoustic properties will be examined. Mineral (stone) wool of different thicknesses will be used as a sound absorber. The test results showed that when testing materials at high frequencies, there is a slight difference in sound absorption, panel materials show worse results compared to solid wood, and the fir sample with the addition of an absorber shows better results compared to the oak and beech sample.
