Modelling and permissions

Possible noise sources per sector:

load-handling equipment
single lines and equipment
ventilation and heating systems
various technological processes
cars
vans
heavy trucks

other...

According to the noise measurement results obtained, nominal characteristics of noise sources, LST ISO 9613-2: 2004, ECAC. CEAC Doc. 29, XPS 31-133, RMR-SRM II-1996 and other methodologies

We do:
noise level calculations in the environment of residential and public buildings
noise level calculations inside residential and public buildings
noise dispersion calculations around and inside buildings
noise level calculations at building facades
evaluation of the effectiveness of noise reduction measures and selection of the most adequate
Calculation of noise limits:
daytime Ldaytime
evening Levening
