A Computer simulation of noise of construction machinery operating in parallel

Abstract Prolonged, repeated or very intense noise exposure can damage human health. To reduce any dangerous effects of on health, policies and restrictions are enshrined in national law legislative regulations. In the Czech Republic, this issue is subject to Ministry Health. other states it be Health more often Environment. The protection health against vibration Act No. 258/2000 Coll., Protection Public Health, specifically şş 30-34 Act. Other described 309/2006 which regulates requirements for safety at work labour relations ensuring activities provision services outside relations. Furthermore, hygienic limits workplaces, protected indoor areas buildings outdoor set new Regulation Government 272/2011 Coll. as amended. This also sets construction noise. They limitations so-called buildings. limit equivalent sound pressure level A from here by adding a correction 5dB 15dB according type space basic value 50dB. must adhered to. For nearby, term „protected facades“ used, i.e. façades“ include nearest that inhabited their occupants could exposed long period time. We measure intensity these places if we have "sound meter". Predicting its longevity future challenging. computational evaluation load area monitored territory based recommended theoretical acoustic transmission stationary sources ČSN ISO 9613/1-2. One possibilities calculating application software programmes used determining traffic noise, which, contrast handled carefully predicted detail during transport infrastructure. Because values methodologies calculation indicators correctly detail, possible use them also, provided well with background input data. falling front façade, determine various measuring points. If acoustically significant elements entered correctly, obtain both correct possibility displaying map colour isophone bands, expresses site surroundings.
