Abstract

Buka je naš svakodnevni pratitelj i čimbenik okoliša koji djeluje akumulirajuće stresno na čovjeka, bez sposobnosti privikavanja.
Izloženost buci može biti direktna i indirektna. Dugotrajna izloženost intenzivnoj buci može vrlo nepovoljno utjecati na zdravlje sluha, u konačnici dovesti i to trajnog gubitka sluha.
Cilj ovog završnog rada je napraviti pregled preporučenih i granično dopuštenih razina buke u okolišu s obzirom na vrstu zvučnih izvora i prijamno mjesto. Poseban osvrt je na propisanim graničnim vrijednostima definiraniranim u „Pravilniku o najvišim dopuštenim razinama buke u sredini u kojoj ljudi rade i borave“. Jednog prijepodneva u vremenu od 11:30 snimljena je buka prometa pomoći zvukomjera. Na osnovu izmjerenih vrijednosti dobili smo tipične indikatore buke koji su sprektralno prikazani.
Prema dobivenim mjernim rezultatima, nakon usporedbe sa zakonom definiranim vrijednostima u Pravilniku, vidimo da neke izmjerene vrijednosti prelaze zakonom definiran iznos buke za vanjski prostor. Iz tog zaključujemo da vrijednosti nisu u skladu sa zakonom i da treba raditi na njihovom usklađenju sa istima. Ponekad je taj proces dosta složen i zahtjeva određenu novčanu podlogu, međutim zdravlje čovjeka i pogodan okoliš za boravak u njemu bi trebao biti prioritetan.
Priroda ne poznaje ni kazne ni nagrade,samo nam vraća onako kako se mi odnosimo prema njoj.

Abstract (english)

Noise is something we encounter everyday as well as environmental factor which affects human beings in such way that it accumulates stress with no ability to adapt. The exposure to the noise can be direct and indirect. Longer exposure to the intensive noise can have negative influence on hearing, and even cause the permanent hearing loss. Purpose of this thesis is to make overview of the recommended and upper limit of noise level in environment considering the type of sound source and reaching spot Special attention was given on upper limit values that were defined in “Regulations on highest noise levels allowed in area in which people work or inhabit“. One morning, at 11:30 a.m. traffic noise has been recorded with sound level meter. Based on the measured valued we got typical noise indicators the we have shown on spectral chart. Comparing measured results with the define values from the “Regulations on highest noise levels allowed in area in which people work or inhabit“, we can see that some measured values for noise level in open space are higher than those defined by the law. Because of it, we can conclude that values are not in accordance with the law and that we should work towards changing it. Sometimes this process is quite complicated and it demands certain money investment, but human health and suitable environment for habitation should be priority.
Nature doesn't know either punishment nor reward, it just repays us the way we treat it.
