INSPECTION OF SOUND ISOLATION ON A NEW BUILDING

Provedeno je terensko mjerenje buke i zvučne izolacije u radnom i životnom okolišu na stambeno-poslovnoj novoizgrađenoj zgradi u Pazinu u ulici M. Belušića prema Zakonu o zaštiti od buke NN br. 30/09, Pravilniku o zaštiti radnika od izloženosti buci na radu NN br. 46/08, Pravilniku o najvišim dopuštenim razinama buke u sredini u kojoj ljudi rade i borave NN br. 145/04. Mjerenje buke izvršeno je zvukomjerom Brüel & Kjaer 2250 te se zvuk, odnosno bijeli šum, reproducirao pomoću uređaja toptalica (5 čekića na bregastoj osovini). Zvuk se mjerio u prijamnoj i u predajnoj sobi kako bi se odredio indeks zvučne izolacije Rw. Nakon analize i obrade podataka dobiveni rezultati uspoređeni su s važećim propisima. U radu su objašnjeni osnovni pojmovi vezani uz opis, mjerenja i utvrđivanja akustičkih parametara te posljedice dugotrajnog utjecaja izlaganja prekomjernim razinama buke kod čovjeka. Pri tome dane su i smjernice te preporuke za zaštitu od buke.In this paper field measurement of environmental noise is conducted in working and living environment in the residential and commercial new building in Pazin, street M. Belušić under the Noise Protection Official Gazette No.30 / 09, the regulations on the protection of workers from exposure to noise at work official national gazette nr. 46/08, regulations on maximum permissible noise levels in areas where people work and live, official national gazette nr. 145/04. Noise measurements were performed by sound-level meter SLM Brüel & Kjaer 2250 and sound or white noise were reproduced by the device for generating sound source Tapping machine (5 hammers in line on a camshaft). Sound is measured in the receiver and in the transmitter room to determine the index of sound insulation Rw. After analyzing and processing obtained results a comparison with the current regulations was made. The paper explains the basic concepts related to the description, measurement and determination of acoustic parameters and the effects on humans caused by prolonged exposure to excessive noise levels. In doing so some guidelines for noise protection are mentioned
