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.
