1.2. evaluating the noise indicators that take into account the duration of the day is 12 hours, the evening, four hours, eight hours of the night. The day is from the Chair. 7.00 to 19.00, yesterday – from noon. 19.00 to 23.00, night – from noon. 23.00 to 7.00 is the sound emission of the referring to the meteorological conditions in terms of annual average;
1.3. Ldvn assessing noise indicators and Lnakt, take into account the direct sound, the sound is not taken into account, which bounce off concrete building facades (adjusted for measurement minus 3 dB (A));
1.4. noise indicators Ldvn and Lnakt evaluation points for the position of the height of the check in accordance with the intended use of the data:

1.4.1. If the calculation of noise mapping in relation to noise exposure in and near buildings, the assessment points to them be 4.0 ± 0.2 m is located (3.8 to 4.2 m) above the ground at the front, which is the most exposed. In this case it is the facade, which is directly opposite and the closest to the specific noise source. If the measurement is conducted noise mapping in relation to noise exposure in buildings and next to them, you can also choose a different height, but it may not be less than 1.5 m above the ground, and the results adjusted to align 4 m height;
1.4.2. If measurements are made to the acoustic planning and noise zoning or other purpose (for example, by developing rural area, which is a one-story building, local measures to reduce the noise impact on specific buildings, or during the detailed noise mapping of a limited area, to determine the noise exposure of individual housing), you can choose a different height, but it may not be less than 1.5 m above the ground.
2. evaluation of the level of LReqj, Tn (dB (A)) for each separate report time interval is determined using the following formula: Tn = LReqj, LAeqj, Tn + Kt + Ki + Ks, LAeqj, Tn – which measured or calculated equivalent continuous A-weighted sound pressure level (dB (A)) a day, evening and night, set in the standard EN ISO 1996-1:2004 "acoustics-noise characterization, measurement and evaluation – part 1: Pamatlielum and assessment procedures". If the noise is Lstund, the equivalent continuous A-weighted sound pressure level is 60 minutes (LAeq60);
KT-noise correction of tonality determined by + 3 dB (A) if certain subjective tonality and + 5 dB (A) if the tonality based on signal analysis of third octave;
Ki-noise impulsitāt's fix, fixed + 3 dB (A), if 15 DB(a) LAeq > LAFmax-10 > in dB (A), and + 5 dB (A) if the LAeq > LAFmax-15 dB (A). LAFmax is the maximum A-weighted sound pressure level set out in standard EN ISO 1996-1:2004 "acoustics-noise characterization, measurement and evaluation – part 1: Pamatlielum and assessment procedures";
KS-acoustic correction of the situation established by + 3 dB (A), if the measurements or calculations are performed in the territory of the points that after building located closer than 4 m of the facades.
3. If the noise is not permanent, the noise level measured in the time interval that includes at least one full cycle of oscillation noise levels, but it may not be less than 30 minutes.
4. If the noise is constant, the noise measurement duration may not be less than three minutes.
5. Noise Measurement markup is 1.5 m above the surface of the territory concerned (if the measurement taken for mapping noise – 4.0 ± 0.2 m).
II. Noise indicators for the evaluation of methods to estimate the noise 6 indicators Ldvn and Lnakt, use the following methods of calculation: no PO box method name guidelines and restrictions in the use of the method 6.1. Standard EN ISO 9613-2:2004 "acoustics-attenuation of sound, it spread as the external environment-part 2: General method of calculation".
Noise emission data (input data) obtained from measurements carried out using one of the following methods: use the industrial operation noise evaluation 6.1.1. standard EN ISO 8297:2004 "acoustics-sound power levels in the industry with many noise sources sound pressure levels in the environment-engineering method for evaluating" 6.1.2. the standard LVS EN ISO 3744:1995 "acoustics-noise source sound power levels with sound pressure-engineering method in the free field sound above the reflective surface" 6.1.3. standard LVS EN ISO 3746:1995 and EN ISO 3746 EN: 2001/AC " Acoustics-noise source sound power levels with sound pressure-review method, using comprehensive measurement surface over a reflecting plane "6.2. Method of ECAC. ECAC Doc. 29 "standard method for calculating the noise contours around civil airports" ("report on Standard Method of Computing noise Contour around Civil airports") 1997 used aircraft noise.
Use the flight trajectory modeling the segmentation technique referred to document the ECAC. ECAC doc. 29 7.5. in subparagraph 6.3 in France developed a calculation method "NMPB-routes-96 (SETR-LCPC-CSTB-CERTS)" referred to in "Arrêté du 5 mai 1995 relatif au of routièr brui des infrastructure, Journal Officiel du 10 mai 1995, article 6" and in the French standard XPS 31-133 uses the road traffic noise assessment. With regard to input data that characterize emissions, these documents contain a reference to "manual motor noise, the noise level of the booklet for forecasting, THURS, 1980" ("guide du transport des terrestr brui, prévision des niveaux fascicul of Sonora, THURS, 1980") developed in the Netherlands 6.4. calculation method "RMR" (published in "Reken-en-En to ' 96, Ministerie Volkshuisvesting, Ruimtelijke Ordening en Milieubeheer, 20 November 1996") used for railway traffic noise assessment taking into account the particular track and traction type 6.5. regulations of DIN 18005-Germany 1 Annex 1, Edition: "1991-09 protection against noise occurring; calculation method; technical noise indicative values for urban planning "Provides car and railway noise source. With respect to railway noise in addition to take account of the specific track and traction type 6.6. German regulations DIN 18005-2, Edition: "1991-09 protection against noise occurring; noise maps, noise emission in the cartographic representation are used in the section that do not conflict with these terms, including the results of the noise mapping presentation 7. To assess the noise indicators Ldvn and Lnakt, the applicable measurement methods laid down in standard EN ISO 1996-2:2004 "acoustics-characterization and environmental noise measurements – part 2: application of the data acquisition of land use" and standard EN ISO 1996-1:2004 "environmental noise acoustics-characterization and measurement and evaluation – part 1 : Pamatlielum and assessment procedures ".
