Abstract

Bukom se definira svaki neželjeni zvuk u sredini u kojoj ljudi borave i rade. Glavni izvori buke u vanjskom prostoru su promet, građevinski i javni radovi, industrija, rekreacija, sport i zabava. Zvukomjer je uređaj za mjerenje razina zvučnog tlaka i njihove raspodjele u frekvencijskim pojasevima od interesa (oktave i terce). Za lokaciju mjerenja buke prometa odabrana je Savska cesta, nedaleko od raskrižja s Koturaškom ulicom. Zahvaljujući različitim metodama mjerenja, dobiven je pregled... More ekvivalentne razine buke na prometnici u svakoj sekundi mjerenja, kao i njen spektralni sastav. Zvukomjerom je izmjerena i ukupna ekvivalentna razina buke LAeq = 73,43 dB(A) što nije u skladu s propisima. Na prometnici se može osjećati psihološko djelovanje te fiziološki efekti (povećava se broj otkucaja srca, raste krvni tlak, modificira se ritam disanja, itd.). Less

Abstract (english)

Noise is defined as unwanted sound in the environment in which people live and work. The main noise sources in outer space are transport, construction and public works, industry, recreation, sport and entertainment. Sound meter is a device for measuring sound pressure level and their distribution in the frequency bands of interest (octaves and thirds). For the location of measuring traffic noise is selected Sava road, not far from the intersection with Koturaška street. Thanks to... More different methods of measurement, it was obtained examination of equivalent noise level on the road every second of measurement, as well as its spectral components. Sound meter is measured total equivalent noise level LAeq = 73.43 dB (A) which is not in accordance with the regulations. On the road canone feel the effect of psychological and physiological effects (increased heart rate, increases blood pressure, modifies the rhythm of breathing, etc.). Less
