NOISE CONTROL REGULATION This Regulation was published in Official Gazette no. 19308 on l 1.12. l (366. SECTION ONE General Provisions Purpose and Scope /-.rude 1 - The purpose c,f this regulation is to ensure U1e creation oi an environment in which noise will not disturb the repose and pew:~, an<! the phys1ea1 and mental healtll of hurnan beings. In Hne witl"1 triis purpose, the R€-gulation encompasses the definition of noise-related terms and the prmciples o! establishing limits for noise control. Legal Foundation Article 2 - This regulation v,;as formulakd on the basis oi articlt? 14 of Environment Law no. 2372 of 9 August I 953. f.rea of Implementation ArtK!e 3 - This regulation shalt be implemented within the boundaries of municipalities and the areas adjacent to them and in areas outside such t>oundaries. · D(::ftn1tions /-,rticle 4 - The terms used in this regulation and requiring explanation are dE:ftned as follov,JS: 1) Sound: A physical phenomenon produced when '•Haves caused by air prl'!ssure from a vibrating source stjmulat.e a lrnrnan being·s sense of h~anng 2) Noise: A sound spectrum with an arbitrary structure which is defined sub1ectively as unwanted sound. 14& 3) Impact Noise: The noise produced by two masses striking each other. 4) Noise Effects: The effects of noise on human health and comfort, which may divided into four groups: pl1ysica1 effects in tlrn form of impaired hearinr: physiological effects on bodily functions; psychological effects such as d1scomf ort and irr1tabi1ity; and effects on performance such as reduced work. efficiency and t11e inability to understand sounds heard. S) Vibration: In general, low frequency, high amplitude mechanical vibrations wllich am propagated in solid media and experienced U1roug11 the sense of touch. 6) Vibration Impact Threshold: The threshold of damage to structures due ~ the physi~logical and psychological effects of vibrations, such as motion sickness, wluch affect human health, performance and comfort, and the criteria of vmich are expressed in terms of the rate, acceleration, amplitude, frequency and duration of tl1e vibration. 7) Sound pressure level or noise level: Tile difference between atmospheric pressure, Which varies during transmission of sound and equilibrium pressure. The decibel (dB) is the unit of sound pressure' level proportional to the standard reference sound pressure level of 0.0002 Newton/m2. The decibel is the unit of perceived sound intensity such that a given sound is said to be a number of decibels above the minimum audible intensity equal to ten times the logarithm to the base 10 of the ~ntensity of that sound in absolute units divided by U1e minimum audible mtens1ty. Ten decibels equal one bel. Sound intensity level is defined in the following way: Lp:::; 10 log ( ,P, ~)2 = 20 log ( ...P ,) Po Po Here, Lp,. Level of sound intensity (dB) P = Sound pressure (N/m2) Po= Reference sound pressure (2 x 10-4 N/m2 according to TS 137). &) dBA: The unit of measuring sound with particular emphasis ou the medium and high frequencies to which the human ear is the most sensitive. The dBA unit, wl1ich 1s 1requent1y used in noise reduction and control, is related to the subjective perception of sound. 9) Frequency: The Hertz is the unit of frequency, that is, the number of vibrations of a sound wave per unit time. 10) Frequency spectrum: The graph produced following the analysis of sound pressure levels pertaining to sound waves of different frequencies, as in noise. I I) Equivalent noise level (Leq): A noise criterion in dBA g1v111g the average level of sound energy or sound pressure exhibiting continuity within a given period. It is represented by the symbol Leq and calculated as follows: l Leq = 1 o log ·ii n : number of noises Lr noise levels, dBA n '/ 10 10 Lj dBA 12) Railroad Leq level: A noise criterion used in evaluating railroad line noise in which transport.at.ion density and the sound levels of the locomotive and the railroad cars are separately taken into account. It is calculated in the following way: Leq = NELT = 10 log N - 49 dBA . NELT = 10 log (lo NELc/ 10 = 10 NELLI 10) . NELc = LAc: max= 10 log 10 Tc NELL= LALi ma/" 10 tog 10 TL ! LAcmaxana LALmax : Point levels, dBA, during passage of locomotive and railroad cars. . Tc and TL 150 : Effective passage times of locomotives and railroad cars. 13) Maximum noise leve-1 = Peak level = Maximum level (Lmax) : Th'::' highest level that sound, which fluctuates with time, has at any given moment. 14) Noise Ind'3X: (WECPNL) A unit envisag<?d by the International Civil Aviation Organization (!CAO) for use in evaluating the noise of ;: itrcraft at, and in the immediate vicinity of, airports. As a calculation it includes the type of airplane, the frequency spectrum of the noise, tile duration of the flyover, and daily flight intensity.

Buildings on public or privat.€'ly o·llfled property which, owing to Urn activities taking place inside U1em, must be protected from excessive noise eiU1er because their acoustics necessitate 1t, or because discomfort from outdoor noise- is at a maximum, or m order that desirable sounds can be heard optimJlly. Such places as residences, hospit3.ls, schools, motels, pensions, rest facilities, recreational parks and cemeteries, for example, can be divided into areas of extreme and normal noise sensitivity, 16) Outdoor Noise Levels: Noise levels measured or calcu!at€-d out.doors at a distance of 1.00 meter from the exterior -walls of buildings . 17) Indoor Noise Levels: Noise levels measured or calculated in spaces where various activities take place indoors. l 5 J I.~) Noise Control: The process of eliminating altogether or reducing to a rE-asonable level sounds in the nature of noise em1ttecl from a sou.nd sc-u.rce o! any kind by reducing them to an acceptable level, modifying tlleir acoustic properues, sl1ortening U1eir effective duration, or masking tl1em w1tll a pleasant or Jess annoying sound. Noise control may be effected .s-1ther at U1e noise source, in the environment where t11e noi3A is propagated, or at the user affected by tile noise. 19) Environment.al Measures: Noise control oi all tinds that can be undertaken in an environment where sounds arising from indoor or outdoor noise sources are propagate<! nntil they read1 buildings or users inside Uwm. 20) Measures at U-1e Noise Source: l.1easures that may be implemented in r:onnectlon with the structure of tile noise producing source of sound, t11e mode of operation, tile ground where 1t is situated, the way it. is mounted, or similar measures relating directly to the source itself. 2 1) Moise Certificate: A certificate regarding t11e noise produced by aircraft issued by the International Civil Aviation Organization and confirming their compliance W1U1 the cntE:ria. 2 2) Reverberatrng courtyard. A form of courtyaHl v.,1•tich causes nrnltiple reflection of sounds off perpendicular smfaces, such as opposite walls, giving rise to an echo and an increased amount of noise. 2 3) Background Noise< A continuous background noise created sunult.l.n&ously by sources of noise other than Uw noise source being examined in an environment. 2 4) Sound Transmission Codficient. Tlw basic unit or measuring t1w sound insulation of a structural element; sound int.ensities reaching the surface of a structural element are different from those transmitted to the back of it; When this d1!f erence is determined by a logarithmic criterion, 1t. is called sound conducuv1ty loss "' sound transmission loss. The unit is tile decibel. Transm1ss1on losses vary depending on the characl:.€-ristics of t11e structural element and the frequencies of tile sounds. 2 S) So'JncJ Absorption: Conversion of the energy in a sound wave striking the surface of a structural element into heat energy due to friction in the element's pores and, th€'reforn, a reduction in the sound energy reflected from that surface. 26) Sound Insulation: Measures of a11 kinds that can be taken in t110 construction of tlw structural elements and in the materials and components used in order to reduce the amount of sound transmitted by the structural elements; in other words, to increase their soun(\ conductivity loss . 27) Physical Environment Factors: Noise-enhancing or -reducing elements of all kinds which are found in the physical environment through w11icl1 the sound passes as it is transmitted from the source to the user, building or aifected persons and Which affect the propagation of the sound. 23) Acoustic Shadow Zone: An area in W11l<;h sound revels are reduced by up to I 0-15 dBA; t11is is achieved when the sound 1,qaves propagated in an environment undergo blocldng or <:Hffraction as a result of such e1.i.ernal effects as obstacles, wind, and daily temperature fluctuations. 2 9) Noise Reduction Coefficient (NRC): A unit which is important in the perception of speech and which gives average sound absorption coefficients of materials in a frequency range between 250 and 2000 Hz: Cl.250 t- cx.500 t- cx.1000 t- (t.,2000 NRC= 4 c1..: sound absorption coefficient (0.0 - 1.0) 30) RevHberation Time: A criterion for c!et.ermining the acoustical properties of a space; tile period of time in seconds that elapses from the cessation of a source of sound Within a space until the sound level falls to 60 dB.

SECTION TWO Sources o1 Noise: Highways, Aircraft., and Industrial, Road Building and Construction Machine-ry Article 6 - Industrial, Road Building and Const.ruction Ivlacllinery I) The various noise sources and the maximum noise levels permitted from t.hese sources are given in Annex l. It is unlawful to operate, put into service or use machines that produce noise in excess of these levels without taking the necessary measures. 2) Construction Site Noise Levels: When these exceed the acceptable levels given in Table 4 at a distance of one meter from noise sensitive structures in the environment, measures shall be taken by the officials specified in this regulation to reduce the working hours of the site or to halt the construction. Article 7 - Highway Vehiqes 1) It is unlawful to opHate, or cause to be operated, a motorized land velliclE» without a muffler or other sound silencing parts. The muffl~r or other silencing part on a motor vehicle or motorcycle may not be removed or rendered inoperable except for maintenance, repair or other purposes of modification. 2) The noise produced by motor vehicles operated in public places may not exceed U1e limits given in Annex 1. 3) It is unlavvful !or sound not o! a warning nature to be pro<luced by a horn or other sound-producing device either on or inside a motor vehicle. Vehicle warning horns must be 105-118 dBA at a dist-'J.nce of 2 meters from, and a height of 1.20 m above, the vehicle and within a frequency spectrum of lM0-3550 Hz in measurements mad~ in accordance with TS 1875 and TS 2214.

Article 9 - Aircraft and Railroads 1) Aircraft operated by Turkish and foreign airlines must have a noise certificate in order to make takeoffs and landings at Turkish airports o~n to domestic and foreign traffic. Turkish and foreign aircraft not possessing such noise certificates may make takeoffs and landings at Turkish airports open to domestic and foreign traffic by paying noise comp€-nsation. The principles governing such compensation shall be determined by the Ministry of Transport and published in the form of communiques. 2) Noise produced by suburban and inter-dty trains and by light and heavy subway systems may not exceed the limits given in Annex 1. Artlcle 1 O - Minimum noise takeoff ancl landing patterns for aircraft shall be determined by the Ministry of Transport at airports where deemed appropriate by the Ministry and where deemed necessary by the Prime Ministry General Directorate of Environment in accordance With the formulation of airport noise plans. Article 11 - Noise at Workplaces 1) The maximum noise levels acceptable with respect to auditory health 3hall be based on the values given in Table 2. 2) In the inspections conducted by the officials indicated in article 5 of this Regulation, owners of workplaces and managers of publicly O\>;ne<l workplaces who have been determined to have set up a work pattern which exceeds the limits given in Annex I and article 11 shall t>e request.eel by the highest official of the central government in the area to rectify the situation v.ithin one month. Noise control shall be undertaken bearing in mind that the sounds propagated by the bodies and exhaust gases of industrial machiMry and equipment depend on the structural characteristics of the equipment, the position and connect.ions of the sourcE> inside tl1e building, and the 0U-1er sound ri:flecting surfaces in the environment, and that the impact sounds and mechanical vibratwns propagated by tlle structural elements depend on the structure of U1e equipment, the way it is mounted, its mode of operation, the work being done, maintenance and the number of pieces of equipment used The activities of factories and workplaces that fail partially or completely to fulfill this requirement shall be temporarily or permanently suspended 5) When the noise levels recommended at workplaces are exceeded, or when the technical capacity for reducing noise and vibrations at the source 1s inadequate, the employer is obligated to provide workers with the protective dothing and equipment specified in Labor Law no. 1475. SECTION THREE Residential Areas, Construction, Materials 1-,rt1cle 12 - Basic Criteria for Residential Areas: l) The basic criterion for traffic noise shall be 35-45 dBA. The revisions given in Table 3 may be implemented depending on the location of the r~s1dential area and the time of day. 2) For other noise sources, noise levels at a distance of 1.00 m from t;uildings may not exceed the limits given in Table 4. 3) The values given in Table 5 shall be used for acceptable indoor space noise pressure levels depending on the types of buildings found 1n the residential area. 4) 0€signs for architectural projects should be based on the noise sensitive areas of activity and noise source areas inside buildings given in Table 6. Article 13 - Basic Criteria for High mys, Railroads, and Building Plans 1) Within the framework of the principles laid down in this Regulation measures shall be taken to ensure that noise plans are drawn up by the municipalities shOwing levels of noises emanating from existing highm~s and main arteries within cities and from belt.line roads around them within a minimum distance of 300 m from the noise source, and to ensure noise reduction in building plans. 2) Bearing in mind the problem of noise when planning in-city and inter city roads, the Ministry of Building and Public Works, the Ministry of Transport and the Municipalities shall carry out the projects required in such areas as removing heavily travelled roads from noise sensitive areas, reducing the elevation of roads with a traffic density of more than 10,000 w-hicles/hour that must pass through settled areas and situating them in 15n ravines or declivities, choosing types of pavement for certain segments of road tliat will produce a minimum of noise, arranging for road education, reducing noise by ensuring the smooth now of traffic by means of traffic lights at corners and intersections, designating appropriate stops, constructing noise barriers along the sides of roads, taking measures to sllift new roads and heavy traffic outside of residential areas, restricting heavy vehicles to certain roads and setting speed limits. Suell efforts wm be coordinated by the Prime Ministry General Directorate of Environment. 3) Coordination among the Ministry of Building and Public Works, t11e Ivlinistry of Transport and the Provincial Governors Offices sha11 ensure that noise measurements are takE;>n of all trains and locomotives, that locomotives are fitted with silencers for controlling noise on non-standard trains, tllat brakes are mod1fied to accommodate disk brakes, that modifications are introduced in engine structure, that the wt1eels of locomotives and railroad cars are properly adjusted and lubricated and that sound absorbing materials are used in their construction, that rails are frequently ground and polished, that rubber wedges are placed at regular intervals on the tracks, that rail connections are properly welded, that railroad turnabouts are appropriately shaped, that shoulders are covered with a material that does not transmit vibrations, that railroad codes are adjusted for the environment, and that the sound absorbency of the internal surfaces of railroad embankments are enhanced. 4) For Subvvays . The Municipalities shall take measures in line with the foltowing principles to control urban subway noise and vibrations in sub"\',ays themselves, at stations and on the lines through which the trains pass. . Permissible noise levels at arrival, departure and -waiting platforms and for ventilation shafts are given in Table 7. . Acoustical measures shall be implemented on walls and ceilings to control reflected sound in underground stations. Reverberation time at 500 Hz must be 1.2-1.4 seconds when the station is empty, and the noise reduction coefficient (NRC) of the acoustic material to be used 1nside shall be assumed to be a minimum of 0.60 and the minimum absorbency coefficient to be 0.60 at 500 Hz . The wall and ceiling area panelled with absorbent material may not constitute more than 35% of the total and not more- than 50% of the ceiling. Nofse barriers shall be constructed in noise sensitive areas through which subways pass bqth inside and outside of cities. . Ar%s w11ere fans and other noisy equipment is operated shall be removed from spaces for general use; if this is impossible, wall partitions and doors shall be soundproofed. 5) The relevant agencies shall bear in mind the noise factor in the construction of new airports and the expansion of existing ones. 6) Noisy and noise sensitive areas in the pattern of settlement sha11 be taken into consideration by the municipalities within the scope of the building plan. This shall be done by the local representatives of the central government in residential areas With less t11an 10,000 population where no need is felt tor a building plan. 7) Among the characteristics of noise sources, the following shall be borne in mind in planning decisions: the percentage of heavy vehicles in the volume of traffic, daily frequency of trains, type of brakes, airport capacity and areas to be allocated for their facilities, types and areas of industry, and preliminary specifications for p·ermanent or temporary construction sites, and the future developments envisaged in these noise sources. The following shall be reviewed: the purposes for which tots are to be used, service areas, and hOw the relationship among them will be affected by environmental noise in areas where dense population is envisaged. Among physical environmental factors, acoustic shadow zones created by climate related components such as land topography, the plant cover and groups of trees, wind and temperature fluctuations, and natural and artificial obstacles shaU be used as noise control elements in planning. li) In drawing parcelling plans and maps, buildings shall be shaped an-:i placed in such a way as to protect from noise all areas of activity within building environments and noise sensitive spaces among blocks of buildings. 9) For noise control in the construction of large-scale building projects and in the dratting of architectural projects, factors such as the type of construction, arrangements of building groups, number of stories, spaces between buildings, orientation of buildings, types of buildings, architectural plans, geometric shapes and dimensions of masses and sound reflecting properties of outer .....rans shall be borne in mind. Buildings and areas of ;:\divity shall be appropriately oriented according to the noise source. care >halt be exercised so that narrow facades With few Vlindows will face noise sources or noisy areas whereas broad facades with many wi.ndom will face the quiet·part of the tot. To ensure similar conditions on two sides of a block of buildings having eqUivalent functions on only one racaM, the buildings shall be situated perpendicular to the noise source. In the parcelling of land for courtyards, front and back yards, terraces, shared outdoor recreational spaces and parks, and in the arrangements required in crowded areas, walls with few windom and non-sensitive spaces shall be created on the broad, non-reverberating and quiet exterior facades in the middle of the lot. The buildings to be situated on either side of a highway shall be arranged in such a way as to avoid mutual sound reflection. To protect noise sensitive buildings and sensitive areas inside buildings, mounds of earth planted with grass and curtain v.ralls covered with greenery may be incorporated at a sufficient distance between the building and the noise source. The ground cover between the noise source and tile building sl10utd consist of soft grass or earth, and hard surfac% should be avoided 10) To prevent discomfort and deterioration of health from noise inside buildings in residential areas, sound insulation shall be used by property owners in the structural elements, tile interior and exterior wall coverings, the ceilings and the roof in the construction of new buildings and in major repairs of old buildings. 11) An appropriate type of construction shall be selected depending on the difference between tile maximum permissible noise levels given in Table 4 based on the existing noise levels 100 m from the exterior walls and the estimates of future noise levels and tyf)€s of spaces involved. For a given coefficient the following characteristics of the surface shall be borne in mind: the smoothness or porousness of the surface, whether it is in layers or solid, the space between the layers and the -way the layers'of insulation material am connected to each otiler and to the other structural elements, the number or such connections, the total area of the wi.ndom, their placement in the wall, the tllickni?Ss and type of glass, details of the woodwork and wall connections, and the total area of the structural el~ments. 12) TSI standards shall be used to determine tlw sound transmission loss% of structural elements, such as building, v:all and ce1!rng coverings, depending on U1e type of construction materials used. 13) In l)UiWings 'w'l1,s,re t11ey deem it necessary t11e Municipalities may 159 request acoustical reports in order to control indc,or or outdoor i;>nv1ronmental noise 1-i) Insulation against such sounds as water pumps, elevators, household Zippl!ances, garbage c.hut.es, plumbing, radios and te1ev1;.1◊ns, ½111ch are transmitted by means oi iloors, ceilings and conunon walls 111 attached tu!ldmgs, shall be incorporated m such a way as to ensure c~mpliance with tlie standards publist1ed by me Turki;,h Standards Institute'. and ~he ad.equacy of such insulation sha11 be checked by the rnumc1paht1es usmg the rneasuring meU-1ods envisaged in the same standards. 15) In existing buildings, measures shall be taken against sounds which ans(;> from act1vit1es in t11e building or in spaces used for purposes other Uian U1ose designated and v,mich are transmitted to other parts of t11e t,u1ld111g by the persons engaging in such noise-producing act1v1ties.
