For night time for protected outdoor area adds more buildings
correction-10 dB, with the exception of traffic noise on railway tracks, where
applies correction of-5 dB.
Rules on the use of a correction referred to in the table below:
1) is used for the noise from the traffic noise from stationary sources, public
the production of the music, the noise on purpose built roads and noise from
railway stations to ensure the work requires train-formation, in particular
rozřaďování and report goods trains, tour trains and repairing cars.
2) is used for traffic noise on the road III. classes and local
roads III. class and rail systems.
3) is used for the noise of traffic on highways, the roads of i. and II. class
and local roads I and II. the classes in the territory where the traffic noise on the
These roads is prevailing over the noise pollution from transport on the other
road safety. It shall apply to the noise from the traffic on rail systems in
the protection zone of the track.
4) shall apply in the case of the old noise from traffic on the road
roads except for roads and rail systems referred to in point
2) and (3)). This correction is maintained even after repaving
the road, carried out by the maintenance and reconstruction of the railway tracks or
the extension of the roads, while maintaining directional or vertical ground
communication, or tracks, which must not lead to deterioration of the existing
the noise level in a protected outdoor space of buildings or in protected
the outdoor space, and for short routes. This correction is
Furthermore, it's even in protected outdoor areas of the buildings at the location of the
apartment in annexe or superstructure of the existing dwelling object, or
multi-purpose object or in the case of the construction of the unique living,
or a multipurpose object within the completion of construction, and the construction of
isolated residential or multipurpose objects within a completion center

Part (C)
How to calculate the limit of vysokoenergetického impulse noise hygiene
Equivalent sound pressure level (C) LCeq, T vysokoenergetického
impulse noise is calculated from relations
LCeq, T = 2.0 LCE-93 + 10. lg (N/N0)-10. lg (T/T0) for LCE > 100 dB
or
LCeq, T = 1.18 LCE-11 + 10. lg (N/N0)-10. lg (T/T0) for 100 dB, the LCE <
where N is the number of pulses per time T [s], N0 = 1 and T0 = 1 s.
Annex 4
Criteria for the identification of impulse noise
A high-energy pulsed noise and high impulse noise is considered to be
noise under section 2 (b). (c)), and (d)), which meets at the site assessment for
individual pulses of at least one of the following conditions is true:
LASmax > LAImax-5 dB
LAImax-LAE > 5 dB,
where
LAI is the maximum level max sound pressure level and dynamic characteristics of the instrument (impulse)
LASmax is the maximum sound pressure level and during dynamic charakteristiceměřidla with (Slow)
LAE is sound and the level of exposure.
