814.41 order on the protection against noise (OPB) of December 15, 1986 (Status January 1, 2016) the Swiss federal Council, view the art. 5, 12, al. 2, 13, al. 1: 16, al. 2, 19, 21, al. 2, 23, 39, al. 1, 40 and 45 of the law of 7 October 1983 on the protection of the environment (law), stop: Chapter 1 provisions general art. 1 purpose and scope of application this order is intended to protect against harmful or bothersome noise.
It regulates: a. the limitation of noise emissions from the operation of new or existing facilities within the meaning of art. 7 of the Act; b. the demarcation and equipment of building zones in areas exposed to noise; (c) the assignment of the building permits for buildings with sensitive space to the noise and located in sectors exposed to noise; d. insulation against noise outside and inside of the new buildings with premises sensitive to noise; e. insulation against noise of existing buildings with sensitive space to the noise; (f) the determination of the outside noise immissions and their assessment from exposure limit values.

It does not govern: a. protection against noise generated on the surface of an operation, insofar as it affects the operating buildings and apartments that are there; b. the protection against infrasound and ultrasound.



Repealed by no I of O from 12 Apr. 2000, with effect from May 1, 2000 (RO 2000 1388).

Art. 2 definitions fixed installations are buildings, infrastructure for traffic, building equipment and other non-mobile facilities whose exploitation product outside noise. They include party roads, railway facilities, airfields, the facilities industry, arts and crafts and agriculture, the shooting facilities as well as the ongoing military exercise and shooting.
Are also considered new fixed installations fixed installations and constructions which the assignment is completely changed.
Emissions limitations are technical measures, construction, operating, and orientation, distribution, traffic calming, or restriction applied to facilities, or of the construction measures taken on the way to spread programs. They are intended to prevent or reduce the formation or spread of outside noise.
Sanitation is a limitation of emissions for existing installations.
Exposure limit values immission limit values, values of planning and the alarm values. They are determined by the kind of noise, the time of day, the assignment of the building and the sector to protect.
The premises whose use is sensitive to the noise are: a. parts of dwellings, excluding kitchens without habitable, sanitary premises and of reduced; (b) the premises of farms, in which people stay regularly during an extended; are excluded the premises for the care of animals and the premises where there is significant noise inherent in exploitation.

Chapter 2 vehicles, devices and mobile machinery Section 1 Limitation of emissions for vehicles art. 3 emissions of noise due to motor vehicles, aircraft, ships and rail vehicles must be limited insofar as this is feasible in terms of technology and operation, and economically bearable.
For the limitation of the emissions will apply legislation on road traffic, civil aviation, inland navigation and railways, when a vehicle is subject to one of these laws.
For the limitation of emissions of other vehicles, will apply requirements for devices and mobile machines.

Section 2 Limitation of emission devices and mobile machines art. Principle 4 emissions of noise produced by devices and mobile machines will be limited: a. to the extent where this is feasible in terms of technique and exploitation and economically bearable, etb. in such a way that the affected population is not significantly hampered in his well-being.

The enforcement authority orders measures which are in operation or construction, or measures to ensure a maintenance in the State of the art.
When the operation or use of arms, aircraft or military machines do not allow to avoid the important and annoying noise immissions, the enforcement authority granted relief.
Emissions generated by machines and devices which are used to the operation of a fixed installation are limited by the requirements on fixed installations.

Art. 5Evaluation of conformity and marking of devices and machines, devices and machinery intended for use in the open air will be commercially only after have passed an assessment of their compliance and have been marked.
The federal Department of the environment, transport, energy and communications (DETEC) sets: a. the types of devices and machines subject to the evaluation of conformity and marking; b. limiting preventive programs and marking requirements, taking into account international standards; c. the documents to be submitted for assessment of compliance; d. procedures of expertise measurement and calculation; e. subsequent controls; (f) recognition of the expertise and foreign markings.

Art. 6 directives on noise from construction sites the Agency federal environmental issues directives on construction and operating measures to limit the noise from construction sites.

The name of the administrative unit has been adapted in application of art. 16 al. 3 o from 17 nov. 2004 on official publications (RS 170.512.1). This mod has been taken throughout the text.

Chapter 3 new fixed Installations and altered art. 7 limitation of emissions from new stationary noise of a new fixed emissions will be limited in accordance with the provisions of the enforcement authorities: a. to the extent where this is feasible in terms of technique and exploitation and economically bearable, etb. in such way that the noise immissions due exclusively to the installation in question do not exceed the values of planning.

The enforcement authority reductions insofar as respect for the values of planning would be a burden disproportionate to the installation and that the latter has an overriding public interest, including in terms of the land use planning; The values of immission limits must not, however, be exceeded.

New content according to chapter I of the O of 16 June 1997, in force since August 1, 1997 (RO 1997 1588).

Art. 8 limitation of emissions from fixed facilities changed when an already existing fixed installation is modified, the new or modified installation items noise emissions should, in accordance with the provisions of the enforcement authority, be limited insofar as this is feasible in terms of technology and operation, and economically bearable.
When installation is significantly changed, the whole installation noise emissions should at least be limited so do not exceed values of immission limits.
Changes, additions and changes of operation caused by the holder of the plant are considered significant changes of a fixed installation when there is reason to expect that the facility or the use of existing communication channels will result in the perception of noise immissions high. The reconstruction of facilities is considered in any case as a significant change.
When a new fixed installation is changed, the art. 7 is applicable.

New content according to chapter I of the O on June 30, 2010, in effect since August 1, 2010 (RO 2010 3223).
New content according to chapter I of the O of 16 June 1997, in force since August 1, 1997 (RO 1997 1588).

Art. 9 increased use of the channels of communication operating fixed facilities new or significantly modified must not lead to: a. an exceeding of the values limits resulting from the increased use of a forgotten the source channel immission. the perception of noise immissions higher because of the increased use of a channel of communication that requires a cleanup.

Art. 10 acoustic insulation of existing when buildings for new or substantially modified, public or dealers fixed installations, it is not possible to meet the requirements in art. 7, al. 2 and 8, al. 2, or in art. 9, the enforcement authority requires owners of existing buildings exposed to noise to soundproof windows from noise sensitive premises within the meaning of annex 1.

Owners of buildings may, with the consent of the enforcement authority, apply to their buildings to other soundproofing measures, if they reduce the noise inside the premises in the same proportion.
The soundproofing measures should not be taken when: a. it can be assumed that they will not bring a noticeable reduction in noise in the building; b. the overriding interests of the protection of sites or historic monuments are opposed; c. the building likely will be demolished within three years following the commissioning of the new or modified installation or that , within that period, the concerned premises will be assigned to use insensitive to noise.

Art. 11 cost the holder of the new or substantially modified facility supports them fresh limitation of emissions caused by its installation.
When the owner of a building must take measures of acoustic insulation to the senses of the art. 10, al. 1, the holder of the plant Additionally pays local customary charges, duly justified, to: a. the establishment of the project and construction management; b. necessary soundproofing of the windows within the meaning of annex 1 and the necessary adaptation work arising therefrom; c. funding if, despite the request in advance of costs made by the owner of the building , the holder of the plant has paid no deposit; (d) any taxes.

When the building owner must take measures of acoustic insulation to the senses of the art. 10, al. 2, the holder of the facility supports local customary charges, duly justified, for as much as they do not exceed those of the al. 2. other fees are the responsibility of the owner of the building.
When limitations of emissions or acoustic insulation measures must be taken due to the noise produced by several facilities, fees resulting will be distributed proportionately to the emission of noise from each of the installations concerned.
The costs of maintenance and renewal of the soundproofing measures are the responsibility of the owner of the building.

Art. 12 controls the enforcement authority will ensure, at the latest one year after the commissioning of the new or modified installation, that emissions restrictions and the soundproofing ordered measures were taken. When in doubt, she reviews the effectiveness of the measures.

Chapter 4 facilities fixed existing Section 1 consolidation and measures insulation acoustic art. 13 consolidation for fixed installations which contribute significantly to the immission limit values are exceeded, the enforcement authority orders the necessary consolidation, having heard the owner of the installation.
The facilities will be reorganized: a. to the extent where this is feasible in terms of technique and exploitation and economically bearable, etb. in such a way that the values of immission limits no longer exceeded.

When no overriding interest there objects, the enforcement authority gives priority to measures that prevent or reduce the formation of noise rather than to those that prevent or reduce only its spread.
Sanitation should not be undertaken when: a. the values are exceeded limits immission button only building zones which are not yet equipped; b. based on cantonal law for construction and development of the territory, planning, design or construction measures are taken at the place of the emission of noise, which allow to respect the values limits of immission until expiration of the deadlines set (art. 17).

Art. 14 relief in the case of the executing reorganization gives relief insofar as: a. sanitation would excessively impede exploitation or would entail disproportionate costs; b. overriding interests, particularly in the areas of the sites, of nature and landscape protection, safety of traffic and exploitation as well as to the general defence oppose sanitation.

The alarm values, however, should not be exceeded by private facilities, not dealers.

Art. 15 sound insulation of existing buildings where for fixed installations, public or dealers, it is not possible to respect the values of alarm due to relief, the enforcement authority requires owners of existing buildings exposed to noise to soundproof windows for sensitive use premises as defined in annex 1, to the noise.
Owners of buildings may, with the consent of the enforcement authority, apply to their buildings to other soundproofing measures, if they reduce the noise inside the premises in the same proportion.
The soundproofing measures should not be taken when: a. it can be assumed that they will not bring a noticeable reduction in noise in the building; b. the overriding interests of the protection of sites or historic monuments are opposed; c. the building likely will be demolished within three years following the order to take acoustic insulation measures or that , within that period, the concerned premises will be assigned to use insensitive to noise.

Art. 16 cost installation holder bears the costs of remediation of its installation.
The holder of a public or dealer installation support in addition, according to art. 11, the fees of the soundproofing measures applied to existing buildings, where it has not been possible, within the meaning of art. 20, al. 2, of the Act, to be released from this obligation.
When there is place to sanitation or to take measures of sound insulation due to the noise produced by several facilities, the resulting costs will be distributed proportionately to the emission of noise from each of the installations concerned.
The costs of maintenance and renewal of the soundproofing measures are the responsibility of the owner of the building.

Art. 17 times the enforcement authority sets deadlines for sanitation and the soundproofing measures based on the urgency of each case.
Are crucial to evaluate the urgency of a case: a. the importance of values exceeding of immission limits; (b) the number of people affected by noise; (c) the cost-utility ratio.

Sanitation and the soundproofing measures will be carried out at the latest in the fifteen years following the entry into force of this order.
The deadline to achieve the reorganizations and the soundproofing measures on the roads (al. 3) is extended: a. for national roads: until March 31, 2015 at the latest; b. for main roads according to art. 12 of the Federal law of March 22, 1985, regarding the use of the tax on mineral oils to mandatory assignment (LUMin) and for other roads: until March 31, 2018 at the latest.

For the realization of the reorganizations and acoustic insulation on the railway facilities measures, deadlines are fixed in the Federal law of March 24, 2000 on reducing noise emitted by the railways.
Sanitation and the soundproofing measures must be implemented: a. for military aerodromes: July 31, 2020; b. for civil aerodromes where circulate large had: to 31 May 2016; c. for the civilian shooting facilities to be reorganized under the amendment of annex 7, 23 August 2006: November 1, 2016; d. for the places of arms military exercise and shooting: July 31, 2025.

The grants referred to in para. 1, let. a, are part of the overall contributions provided for in art. 13 LUMin. The grants referred to in para. 1, let. b, are awarded globally for the sections defined in the programme agreements concluded with the cantons.

SR 725.116.2 art. 22 request the present township grant for reorganizations and some soundproofing measures applied to the roads referred to in art. 21, al. 1, let. b, the federal Office for the environment.
The request contain information: a. roads and stretches to clean up for the duration of the programme agreement; b. measures sanitation and insulation, as well as their costs; c. the effectiveness of these measures.

Art. 23 convention - the federal Office of the environment program concludes the programme agreement with the competent cantonal authority.
The convention program's objects: a. roads and road sections to improve; (b) the service provided by the Federal Government; c. controlling.

The duration of the programme agreement is four years at most.
The federal Office of the environment shall issue guidelines on the procedure to follow conventions-programs and on the information and documents related to these objects.

Art. 24 rate subsidies the amount of subsidies for reorganizations: a. the number of people who will be protected by the measures, etb. exposure to noise reduction.

For measurements of sound insulation of existing buildings, it is allocated 400 francs per window noise or other construction measure having equivalent anti-noise effects.
The amount of the subsidy is negotiated between the Confederation and the cantons.

Art. 24aet 24b repealed art. 25 payment grants are paid by instalments.

Art. 26 record and control the canton shall report annually to the federal Office for the environment of the use of subsidies.

If, after the duration of the program, it turns out that there has been the performance of imperfectly, the federal Office of the environment requires the correct execution by the canton; It sets a reasonable time for this purpose.
If facilities who received allowances are assigned to another goal, the federal Office of the environment may require the County let him deny this decommissioning or cancels it within a reasonable time.
If the Township is not running correctly delivery despite the injunction of the federal office for the environment or if not renounce decommissioning doesn't cancel it, restitution is governed by art. 28 and 29 of the Act of 5 October 1990 on subsidies (LSu).

RS 616.1 art. 28 abroge Chapter 5 requirements asked of building zones and allowed to build in areas exposed to noise art. 29 demarcation of new areas to build and new areas requiring increased protection against noise new building zones for buildings including a noise sensitive premises, and not buildable areas which require greater protection against noise, can be delimited only in areas where the noise immissions do not exceed the values of planning or in areas in which measures of planning development or construction allow to respect these values.


Repealed by no I of O of 16 June 1997, with effect from August 1, 1997 (RO 1997 1588).

Art. 30Equipement of building areas zones build designed buildings including space sensitive to noise, which are not yet equipped at the time of the entry into force of the Act, cannot be equipped with insofar as the planning values are respected or may be by a change in the mode of assignment or planning measures development or construction. The enforcement authority may grant exceptions for small parts of areas to build.

New content according to chapter I of the O on June 30, 2010, in effect since August 1, 2010 (RO 2010 3223).

Art. 31 building permits in areas exposed to noise when immission limit values are exceeded, new constructions or buildings notable changes including the noise sensitive premises, will be allowed unless these values can be met by: a. available to business premises sensitive to noise on the side of the building opposite to the noise. OU.b. construction or planning actions to protect the building against noise.

If the measures laid down in para. 1 do not comply with immission limit values, the building permit will be issued only with the consent of the cantonal authority and provided that the construction of the building has an overriding interest.
The cost of the measures is the responsibility of the owners of the land.

New content according to chapter I of the O of 16 June 1997, in force since August 1, 1997 (RO 1997 1588).

Art. Special 31aDispositions about airports where circulate large aircraft for airports where circulate large aircraft, the limit values of planning and of immissions limit values according to annex 5, ch 222, for the hours of the night are considered to have been met if: a. no flight operations is planned between 24 and 6 hours; b. the noise sensitive premises receive acoustic insulation against noise outside and inside, responding at least to increased requirements of the SIA 181 of 1 June 2006 of the Swiss standard engineers and architects; and listen to me. bedrooms: 1. have a window which automatically closes between 22 and 24 hours and may open automatically the rest of the time, and2. are built to ensure a suitable climate.

The delimitation or equipment of areas to build authority ensures that the requirements set out in para. 1, let. b and c, are binding for property owners.

Are particularly applicable, against the noise from civil airfields where flow of large aircraft, strengthened requirements, and the noise of the other stationary, the minimum requirements according to the standard SIA 181 of the Swiss Association of engineers and architects.
When the values of immission limits are exceeded and that the conditions set out in art. 31, al. 2 for the assignment of the building permit are met, the enforcement authority strengthens in appropriate requirements for soundproofing of the outdoor elements.

The requirements also apply to the outside elements, the elements of separation, to the stairs and equipment that are transformed, replaced or mounted to nine. On request, the enforcement authority grant relief when meeting the requirements is disproportionate.

New content of the sentence according to section I of the O from 12 Apr. 2000, in force since May 1, 2000 (RO 2000 1388).

Art. 33 external Elements and elements of separation, facilities of the building outside elements define a local towards the outside of the building (for example windows, doors and walls, roofs).
The separation elements delineate between them the premises of different assignment units, such as apartments (e.g. interior walls, ceilings, doors).
The facilities are facilities that are body with the building, such as heating, ventilation, facilities for feeding and evacuation, lifts or washing machines.

Art. 34 request for building permits in the application of building permits, the employer must indicate: a. the outside noise, where the values of immission limits are exceeded; b. the allocation of premises; c. the outside elements and the separation of the noise sensitive premises.

For construction projects in areas where the immission limits are exceeded, the enforcement authority may require information on sound insulation of the external elements.

Art. 35 controls after the completion of the construction work, the control enforcement authority, by scores, if the measures insulation meet the requirements. When in doubt, she proceeds to further scrutiny.

Chapter 7 Determination, evaluation and control of the noise immissions due to stationary facilities Section 1 Determination art. 36determination required the enforcement authority determines the outside noise immissions due to fixed installations or ordered their determination if it has reason to assume that the values in force exposure limits are already, or will be exceeded.
It takes account of increases or reductions in the emission of noise that can be expected as a result of: a. the construction, modification or sanitation of fixed installations, especially if the projects concerned are already authorized or made the public inquiry at the time of sentencing; b. construction, modification or demolition of other works, if projects are already set to the public at sentencing inquiry.

Art. 37Cadastres of noise for roads, railway facilities, the military aerodromes and places of exercise and shooting weapons, the enforcement authority shall in a cadastre (land register of noise) determined in accordance with the art of noise immissions. 36. registers of noise indicate: a. the noise exposure determined; b. the calculation models used; c. the input data for the calculation of noise; (d) the allocation of territories exposed to noise according to the assignment plan; e. degrees of sensitivity attributed; f. facilities and their owners; g. exposure in effect limits the number of people affected by the higher values of noise immissions.

The enforcement authority ensures that registers are checked and corrected.
It gives cadastres to the federal Office for the environment at its request. The office may issue recommendations so that the data is captured and presented in a comparable way.
The federal Office of civil aviation is responsible for the determination of the noise immissions caused by the Basel-Mulhouse Airport in Switzerland.
Anyone can access the cadastres of noise insofar as the manufacturing and business secret or other overriding interests do oppose.

If it is established or fear of noise immissions due to installation differ significantly and sustainably Immissions recorded in the decision, the enforcement authority takes the necessary measures.
The federal Office for the environment may issue recommendations so that the noise immissions recorded in these decisions are captured and presented in a comparable way.

Introduced by section I of O from 12 Apr. 2000 (RO 2000 1388). New content according to section I of the Sept. 1 O. 2004, in force since Oct. 1. 2004 (RO 2004 4167).

Art. 38 methods of determination of noise immissions are determined as a level assessment Lr or Lmax-maximum level on the basis of calculations or measures.
The aircraft noise immissions are in principle determined by calculation. The calculations must be made in accordance with the State admitted the technique. The federal Office of the environment recommends that the appropriate calculation methods.
Models of calculation and measuring equipment requirements will be in accordance with Schedule 2.

Introduced by section I of O from 12 Apr. 2000, in force since May 1, 2000 (RO 2000 1388).
Formerly al. 2 art. 39 point of determination for buildings, the noise immissions will be measured in the middle of the open window of the premises to use sensitive to noise. The aircraft noise immissions can also be determined near the buildings.
On the area not built in areas which require greater protection against noise, the noise immissions will be determined at 1.5 m from the ground.
In building zones not yet built, the noise immissions will be identified here where, in accordance with the law on land management and construction, will be able to be erected buildings including sensitive space to the noise.

Section 2 Evaluation art. 40 values exposure limits the enforcement authority assesses the outside noise immissions produced by fixed installations on the basis of the limits of exposure according to annexes 3 and following.
Exposure limit values also outdated when the sum of the noise immissions same kind, from several facilities, is superior. This principle is not valid for values of planning new fixed facilities (art. 7, para. 1).
When the values of exposure limits are lacking, the enforcement authority evaluates the emission of noise within the meaning of art. 15 of the Act. It also takes into account the art. 19 and 23 of the Act.

Art. 41 validity of values values exposure limits exposure limits are valid for buildings including sensitive to noise space.
They are also valid: a. in building zones not yet built where, in accordance with the law on development of the territory and the buildings, can be erected buildings including a noise sensitive premises; b. on the area not built in areas which require greater protection against noise.

For the buildings and areas in which people stay usually day or night, no value limit exposure will only apply for the night or the day respectively.

Art. 42 limits exposure specific to the premises of farms for the premises of farms (art. 2, para. 6, let. b) which are located in areas where it has awarded the degrees of sensitivity I, II or III, the planning values and values immission limits are 5 dB (A) higher.
The al. 1 is not applicable to the premises in schools, institutions and homes. To the premises of restaurants and hotels, it applies insofar as these premises are sufficiently ventilated, even when the windows are closed.

Art. 43 degrees of sensitivity in areas of assignment according to the art. 14 and following of the Federal law of June 22, 1979 on the development of the territory, the following degrees of sensitivity are to apply: a. the degree of sensitivity I in areas which require greater protection against noise, especially in the areas of relaxation; b. sensitivity II in areas where no troublesome company is allowed particularly in residential areas as well as those reserved for buildings and public facilities; c. the degree of sensitivity III in areas where are admitted the moderately embarrassing business, especially in residential areas and craft (mixed zones) as well as in agricultural areas; d. sensitivity IV in areas where highly embarrassing companies are allowed , especially in industrial areas.

You can downgrade a degree parts of sensitivity I or II assignment areas, when they are already exposed to the noise.

RS 700 art. 44 procedure


The cantons ensure that the degrees of sensitivity are attributed to areas of assignment in the building regulations or the municipal land-use plans.
The degrees of sensitivity will be awarded during the demarcation or change of assignment areas, or when editing of the building regulations.
Before award, the degrees of sensitivity will be determined case-by-case basis by the cantons to the senses of the art. 43....

When federal authorities apply other federal statutes, international agreements or international decisions that affect objects under this order, they also carry out this order. The collaboration of the federal Office of the environment and the cantons is governed by art. 41, al. 2 and 4, of the Act; the legal provisions on the obligation to maintain secrecy are reserved.
Are required to ensure enforcement of the regulations on the limitation of emissions (art. 4, 7 to 9 and 12), sanitation (art. 13, 14, 16 to 18 and 20) as well as on the identification and assessment of noise immissions (art. 36, 37, 37A and 40): a. for railway facilities: 1. the DETEC to the extent where prescriptions are a major rail projects as defined in the annex to the Act of 20 December 1957 on the railways, and where they must be implemented in the context of a procedure for approval of the plans, 2. in other cases, the federal Office of transport;

b. for civilian aerodromes: 1. the DETEC, in far prescriptions concern buildings or facilities within the meaning of art. 37 of the Federal law of December 21, 1948, on aviation, where they used to operate an airport and where they should be performed in the context of a procedure for approval of the plans, 2. in other cases, the federal Office of civil aviation;

c. for the national highways: 1. the DETEC to the extent where the requirements must be performed in the context of a procedure for approval of the plans, 2. in other cases, the federal Office of roads;

d. for national defence facilities: the federal Department of defence, protection of the population and sports; e. electrical: 1. the federal Office of energy, in the case where Federal Inspection of current installations (ESTI) fort failed to settle opposition or remove differences between federal authorities within the meaning of art. 16, al. 2, let. b, of the law of June 24, 1902 on electrical installations, 2. in other cases, the ESTI.

32 average day and night traffic average traffic day and night is the annual average of the hourly traffic between 6 and 22 hours and between 22 and 6 hours.
Hourly traffic day (Nt) or night (Nn) motor vehicles includes two partial traffic volumes that are Nt1 and Nt2 or Nn1 and Nn2.
Traffic volumes partial Nt1 and Nn1 motor vehicles include passenger cars, delivery cars, minibuses, mopeds and trolleybuses.
Traffic volumes partial Nt2 and Nn2 motor vehicles include trucks, articulated lorries, coaches and buses, motorcycles and tractors.
Rail traffic includes all trains that circulate regularly or as needed, including travel of service.

33 determination of average traffic day and night of the average day and night traffic motor vehicles (Nt, Nn) as well as partial (Nt1 Nt2, Nn1, Nn2) traffic volumes are determined steps: a. for existing roads, by counting vehicles; b. for roads which will be built or modified, based on the traffic forecasts.

If the data obtained by the counts of vehicles are insufficient or that there is no detailed forecasts, traffic Nt volumes, Nn, Nt1, Nt2, Nn1 and Nn2 shall be calculated on the basis of the average daily traffic (TJM; vehicles in 24 h): Nt = 0,058 × TJM Nn = 0,009 × TJM Nt1 = 0.90 × Nt Nn1 = 0.95 × Nn Nt2 = 0.10 × Nt Nn2 = 0.05 × Nn the TJM is determined according to the recognized technical rules and planning of the traffic.

34 determination of average traffic day and night trains average traffic day and night of the trains is determined as follows: a. for existing railway facilities, from the schedule and the traffic data; b. for railway facilities that will be built or modified, based on the traffic forecasts.

35 level corrections correction K1 level for motor vehicle noise is calculated from the average day and night traffic as follows: K1 =-5 to N 100 N represents the hourly traffic of vehicles motor Nt or Nn.
Correction level K2 for railway noise is equal to-5. For frequent and clearly perceived gnashing, the correction level is 0.

Status January 1, 2016 Schedule 4 (art. 40, al. 1) limit values for exposure to noise from railways 1 scope values exposure by clause 2 limits apply to the noise of trains running on normal or narrow roads.
Noise generated by trains running on the road is similar to the noise of road traffic (annex 3, ch. 1).
The noise produced by the cable cars as well as by the railroad repair shops, energy production facilities and similar railway facilities is likened to the sound of industry facilities and arts and crafts (annex 6, ch. 1).

95 3 determination of the level of assessment Lrk to the noise caused by the traffic of small aircraft 31 principles the assessment level Lrk for small aircraft traffic noise is the sum of the average Leqk, weighted has, and the correction level K: Lrk = Leqk + K Leqk average level is determined for the average number of hourly movements a day with average peak traffic (number of moves n).
Movement, means each landing and each take-off of a small aircraft. Immediate landing take-off procedures count as two movements.

32 number of moves n for the civilian existing airfields to establish the number of moves n on the existing civilian airfields, it must: a. determine the six months where the traffic is more intense during a year of operations; b. During these six months, determine the average number of flights for each of the seven days of the week; the average daily two days of traffic the most intense in the week are referred to as N1 and N2; c. n from N1 and N2 by taking average twelve hours of day: n = (N1 + N2) / 24 33 number of moves n for new civilian airfields for civil aerodromes that must be built or modified the number of moves n is determined based on the traffic forecasts.
When it is not possible to establish a detailed forecast, n is calculated from the annual number of predictable movements N as follows: n = (N × 2.4) / (365 × 12) 34 Correction of level K-level correction is calculated from the number of movements annual N as follows: K = 0 for N
