underwent recent reconstruction to be capable of storing various data that arose
from measurements of noise emissions [31, 32].
• Acoustic zoning of City of Niš (Fig. 5), as the first and the most comprehensive
endeavour of that type in Serbia, which comprised definition of the acoustic zones
and limiting values of noise indicators, then calculation and measurement of the
indicators, followed by the comparison of the two datasets which allowed the
identification of the present level of danger and definition of action plans [41, 42].
• The NAISS model for calculation of the level of traffic noise in urban areas of
Serbia; the model enables calculation of the equivalent noise level (L eq ) based on
the number of the cars, buses and trucks within a period [26, 27].
Apart from that registered technical achievements were also constructed other
noise protection systems:
• sound insulation of a small mechanical workshop with eccentric presses is located
in a densely populated residential area of a Serbian City ( ˇ
Caˇ cak); starting from
the theoretical model of acoustic insulation power of a single solid partition, a
complex partition and a multi-layer partition, the acoustic insulation power of the
