Studije utjecaja buke na okoliš

Sukladno odredbama Pravilnika o procjeni utjecaja na okoliš (Narodne novine 59/00) kao i Pravilnika o izmjenama i dopunama Pravilnika o procjeni utjecaja na okoliš (Narodne novine 136/2004) DARH 2 d.o.o., izrađujemo dio studija utjecaja na okoliš, poglavlje buke uvažavajući traženu metodologiju iz zakonskih odredbi.

Kao ovlaštena pravna osoba Ministarstva zdravstva i socijalne skrbi, provodimo mjerenje i ocjenu buke u životnoj okolini radi utvrđivanja osnovnih („nultih“) razina buke nužnih za izradu studija utjecaja na okoliš.

Metodama računanog modeliranja možemo izraditi vjerodostojne računalne prognoze razina buke od određenog „budućeg“ izvora buke te provesti analize budućeg stanja razina buke okoliša.

Za metode računalnog prognoziranja razina buke koristimo sve bitne evropske norme, posebno za:

a) Cestovni promet

• "Nouvelle Méthode de Prevision du Bruit - Routes-96" – XPS 31-133. – NMPB.
  
• „RLS-90“; "Richtlinien fuer den Laermschutz an Strassen", izdanje 1990, Bundesminister fuer Verkehr, Abteilung Strassenbau, Deutschland
  
• DIN 18005
  
• CRTN

b) Željeznički promet

• 'Reken- en Meetvoorschrift Railverkeerslawaai' - RMR/RLM2
  
• "Schall 03"; "Richtlinie zur Berechnung der Schallimmissionen von Schienenwegen, August 1990", Regelwerk der DB AG zur Berechnung des Schienenlaerms

c) Zračni promet

• ECAC.CEAC Doc. 29 ‘Report on Standard Method of Computing Noise Contours around Civil Airports’, 1997.
  
• Integrated Noise Model v 6.2, FAA

d) Buka industrijskih pogona

• HRN ISO 9613-2:2000 - Prigušenje zvuka pri širenju na otvorenom -- 2. dio: Opća metoda proračuna
  DARH2 d.o.o. koristi programski paket Bruel & Kjaer LIMA koji je rezultat partnerstva svjetskog proizvođača mjerne oprema za zvuk i vibracije Brüel & Kjaer i Stapelfeldt Ingenieurgesellschaft mbH.

Bruel & Kjaer LIMA 7812 - The LIMA software is developed by Stapelfeldt Ingenieurgesellschaft mbH and is also traded by Bruel & Kjaer. LIMA reduces pre-processing time through its capability for importing a wide range of data types, and automatic checking and correction features such as 'polygon closing'. Efficient model processing is supported by the optional use of commands and macros in the GUI. By using multiple processors or networks, it achieves market-leading speed in the production of detailed maps according to UK and international standards such as ISO 9613-2, NMPB, SRM2 and other German, Austrian and English standards. LIMA can handle several hundreds of thousands of objects - terrain, buildings and emitters – in the calculation of each tile in a model. Each tile may consist of 32 000 x 32 000 grid points. Tiling of even the largest models is automatic. LIMA also copes readily with complex environments such as embankments with barriers, bridges, cantilever roofs, and reflections underneath bridges and roofs. Noise maps for cities such as Birmingham in the UK, Bonn, Stuttgart, Hamburg in Germany and Linz in Austria have been created. On a larger scale regions like Thüringen (18 000km2), Sachsen (20000 km2) and Hong Kong have been noise mapped.
