Kako se izrađuje karta buke

Karta buke izrađuju se pomoću računalnih metoda proračuna emisije i širenja zvuka/buke emitiranih od poznatih izvora buke u geografskom prostoru poznatih karakteristika.

Metodologija izrade karte buke slijedi iz:

• Smjernice 2002/49/EC,
  
• Preporuke 2003/613/EC

a prikazana je na OVDJE.

Tako izrađena karta buke u potpunom je suglasju sa zahtjevima EU i najboljom stručnom praksom i izuzetno je koristan instrument u upravljanju bukom okoliša.

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.
