Environmental Noise

Article I Preliminary

1) Definitions ambient noise A totally encompassing sound in a given situation at a given time usually composed of sounds from near and far. BAT Best available techniques. community noise noise emitted from all sources except noise at the industrial workplace. construction noise refers to noise emitted from building, demolition, refurbishment or directly associated activities.

day refers to the time period between 07.00 and 19.00 hours. decibel Conventional Unit for measurement of noise (dB). Decibels are measured on a logarithmic scale as a result decibel levels do not add and subtract arithmetically. An increase or decrease of 3 dB in the level of a steady noise is about the smallest that is noticeable. It represents a doubling or halving of noise energy. An increase or decrease of 10 dB represents a ten-fold change in noise energy, and is perceived as a doubling or halving of loudness. dose is the total (accumulated) exposure over a period of time. evening, refers to the time period between 19.00 and 23.00 hours. environmental noise Outdoor sound created by human activity. exceptional circumstances refers either to natural events and phenomena, or unique or unusual operating conditions that make compliance impracticable. exposure sound levels which are transmitted to the human ear. habitable room areas within a dwelling house where the majority of time is spent, such that they are sensitive with respect to noise i.e. bedrooms, living rooms and dining rooms. impulse sound Single short burst or series of short bursts of sound pressure. industrial premises refers to any site or facility that extracts, manufactures, stores or processes any product or substance.

LAeq,T Equivalent continuous A-weighted sound level. It is the constant sound level that, in a given situation and time period (T), conveys the same sound energy as the actual time-varying A-weighted sound. LAmax Maximum A-weighted sound level for a given time interval or event. level describes the magnitude of the sound in its physical dimension, whether or not there are humans there to hear it.

night refers to the time period between 23.00 and 07.00 hours. noise means vibration of a frequency within the range of 0-20,000 Hertz. noise sensitive faade The faade of any noise sensitive property that is normally occupied during the relevant time period of day, evening or night and which includes a window and/or door to a habitable room. noise sensitive open space Any area of open land designated as public gardens or recreational space or within the boundary of a premises that is used for recreational or educational purposes, including residential garden space. noise sensitive property Any occupied premises outside the noise emitting premises used as a dwelling (including gardens), place of worship, educational establishment, hospital or similar institution, or any other property likely to be adversely affected by an increase in noise level. Due consideration should be given to national parks, areas of outstanding natural beauty or other outdoor spaces where members of the public might reasonably expect quiet enjoyment of the area. noise emitting premises Premises from which the noise is emitted. operator Refers to any site or facility subject to environmental controls under the General Environmental Regulations. peak sound pressure Maximum absolute value of the frequency weighted instantaneous sound pressure that occurs during a specified time period. PME refers to the Presidency of Meteorology and Environment who are designated as the responsible agency for the protection of the environment and the development of environmental protection standards in the Kingdom of Saudi Arabia. receiver height Distance between the receiver and the local ground level.

reference time interval (T) The time interval to which the rating of the sound is referred. residual noise The ambient noise remaining at a given position in a given situation when the specific noise is absent. Competent Agency is the appointed body that will regulate and enforce these environmental standards. Significant noise emitting premises Premises from which the difference between the emitted noise and the ambient noise level at that location is 10dB(A) or more. source height Distance between the source and the local ground level. sound power The sound energy radiated per unit time by a sound source. specific noise source Refers to the noise emitting party / structure that is under investigation.

2) Citation a) This document may be cited as the General Environmental Standard for Noise. This standard revises the current General Standards for the Environment (specifically document number 1409-01) issued by the Presidency of Meteorology and Environment (PME).

3) Timescales for implementation a) The effective date of this standard is 01/05/1433H

corresponds to 24/03/2012G.

3) Purpose a) The purpose of the General Environmental Standard for Noise.is to provide a basis for statutory control to restrict and reduce the nuisance caused by environmental noise. The framework does not address the issue of occupational noise which falls under the jurisdiction of National Health and Safety Law. b) People may respond differently to the same level of noise. However, above certain levels, noise can adversely affect the lives of many people. It can lead to hearing loss and mental stress and irritation. It can also interfere with daily activities such as studying, watching television, talking on the telephone, resting and sleeping. c) Noise limits are set by the responsible and competent authorities (in this case PME) on the

basis of collective knowledge about the effects of noise on human health and well-being. The limits must also take full appreciation of relevant social and economic factors, technological options, equity, enforceability and the cultural climate.

4) Scope a) This standard relates to the following types of environmental noise:

i) community noise;

ii) noise from industrial units in areas set aside primarily for industrial facilities;

iii) noise from construction activities;

iv) noise from vehicles (including motorised

vessels and recreational craft); and

v) noise from equipment used outdoors. b) The standard does not extend to noise from public transportation, including highways, railways and noise from commercial and private aircraft, including helicopters, both in flight and operating on the ground.

5) Exemptions

a) Exemptions may apply in circumstances where the enforcement of this standard is impractical and/or inappropriate. Exemption in specified areas may be made for, but not restricted to, the activities specified in table 1. The Competent Agency will determine where these exemptions apply and which activities beyond this list are included.

Table 1 Exempt activities

Activity Exemption applies

Call to prayer At all times Military activities At all times Airports, commercial and private aircraft, including helicopters, both in flight and operating on the ground

At all times

Public railways and railroad freight terminals

At all times

Commercial port activity

During operational activities

Expressways At all times b) With respect to events taking place at stadia (e.g. sports) and festivals, the Competent Agency will take account of the frequency of the events and how disturbing they will be. The enjoyment of the particular participants will be balanced against the

nuisance caused to other people and, depending on local circumstance and public opinion, noise emission levels may be set. These may include a limit on the hours of use and the control of noise emissions (including public address systems) during unsocial hours.

6) Powers of Authority a) This standard enables the issue of regulations and technical memoranda which are enforceable by the Competent Agency who hold delegated authority under the General Environmental Regulations. The standard includes provision for the exemption of certain nationalised or religious activities (see part III, 1.4). b) There may be some requirement at a future date to adjust the standards included to recognise specific local conditions and or improved understanding of the effects of noise. c) The Competent Agency or appointed individual for the purpose of this noise standard may:

i) Enter any premises for the purpose of carrying out any investigation. ii) carry out such inspections, measurements and tests on premises entered, articles or records found on any such premises, and take away such samples of ambient air or articles, as may be considered appropriate for the purpose of enabling such investigation; or iii) at any reasonable time require any relevant party to supply him with copies of, or of extracts from, any records kept for the purpose of demonstrating compliance with the environmental noise standards.

7) Enforcement procedures

a) Failure to comply with the requirements of these standards may lead to prosecution by the Competent Agency and those convicted of such failure may be subject to fines or periods of imprisonment as laid out in the General Environmental Regulations. b) It is anticipated that the requirements of this standard will be enforced nationally with inspections taking place to verify their implementation at a regional and local level.

8) Penalty fines

a) Maximum fines that may be imposed for exceeding the applicable standard, breach of permit and failure to comply with an abatement notice are set out in the General Environmental Regulations.

9) Appeals a) A right of appeal exists for any organisation or individual who is required to take action as a consequence of the implementation of the standard. b) The right of appeal against conviction or sentence is available through the appropriate judicial system as set out in the General Environmental Regulations. c) Appeals with respect to abatement notices must be lodged with the Designated Agency for appeals as specified in the General Environmental Regulations.

d) All appeals should be fully supported with a documented case containing as a minimum, the information required under the appeals process of the General Environmental Regulations.

10) Periodic review

a) There may be some requirement at a future date to adjust the standards included to recognise specific local conditions and or improved understanding of the effects of noise. b) As a minimum, PME shall undertake a periodic review of this standard every 5 years.

Article II General provisions

1) Units of measurement

a) Sound waves are very small fluctuations in the atmospheric pressure. Conventionally, in environmental acoustics these are measured as the root mean square pressure over a time interval of 0.5s (slow response), 0.1s (fast response) with units of pascals (Pa) (i.e. Nm-2). In order to express the vast range of pressures representing human hearing sensitivity, the practice is to use the decibel (dB). This is the logarithmic ratio of the measured value to a standard value, the reference sound pressure usually expressed as 20Pa. The word level is added to sound pressure denoting that the quantity has a certain level above a predefined reference value. Throughout this standard all sound pressure levels are expressed in decibels. b) It is general practice to measure the sound level with a meter that incorporates an internationally standardised weighting filter that approximates to this characteristic. The specified frequency weighing used throughout this standard is the A-weighting; an A-weighted sound level is expressed in dB(A). c) For the purpose of this standard, the following condition applies regarding the rounding of results and figures in the unit dB. The convention applied to this standard is that all measured or calculated numbers are rounded up to the nearest whole number

if 0.5 dB or above and rounded down if it is below 0.5 dB. d) The LAmax is a maximum sound level that should not be exceeded at any time. This restriction is included to protect against adverse health effects, annoyance and nuisance from loud single event or intermittent noises.

2) Instrumentation

a) Noise levels shall be measured using an integrating averaging sound level meter or equivalent system confirming to BS EN 60804:1994 or ANSI Standard S1.4-1983 or ANSI S1.43-1997 (R1997), "Specifications for Sound Level Meters," Type 2 or better, or for newer instruments, IEC 61672-1:2002 (BS EN 61672-1:2003), Class 1 or 2.

3) Calibration procedure

a) An acoustic calibrator or pistonphone conforming to Class 1 or better of BS 7189:1989 or either Class 1 or 2 of IEC 60942 should be applied to the microphone to test the sensitivity of the measuring equipment before and after each measurement. Records of these tests must be retained by the equipment operator and produced when required. b) In addition to the field tests in 1.4a more comprehensive calibration tests are required, at planned time intervals, with regard to the performance of the instrumentation. A suitably accredited calibration laboratory should undertake these tests. The minimum period is once every two years for each sound level meter system and annually for calibrators and pistonphones. c) Records of the calibration programme for instrumentation and relevant calibration certificates issued by a certified calibration laboratory may be requested by the Competent Agency.

4) Measurement procedures

a) The measurement of A-weighted continuous equivalent sound pressure levels (LAeq,T) and maximum sound levels (LAmax) shall be carried out at locations representative of the most exposed noise sensitive property or noise sensitive open space. b) The location and number of measurement positions will depend on the required spatial resolution for the environment under consideration. c) The measurement positions shall be chosen (and recorded on a map or suitable plan) bearing in mind the following:

i) Measurements should be taken at a number of locations considered representative of the areas under consideration. Contours of equal noise

levels can then be drawn where necessary by interpolation between the points.

ii) The need to represent the average level

of a specified area taking into account topographical and local shielding from buildings, structures and vegetation.

iii) The need to include all locations which

categorize the noise from various specific noise sources to facilitate the calculation of noise levels elsewhere in the area based on the principles of the outdoor propagation of sound.

d) With the exception of Article VI, the minimum reference time period for measurements should be 1 hour and should, in any case, be sufficient to be representative of the source under assessment.

e) For free-field noise levels, measurements must be undertaken at between 1.2 m and 1.5 m above ground level and, if practicable, at least 3.5 m from any walls, buildings or other reflecting surfaces. The height and location of the microphone should be stated in all reports. f) In cases where outdoor noise level measurements are neither practicable nor relevant, indoor measurements must be made. The measurements must be made with windows open, unless the windows are permanently fixed closed, and at a distance of at least 1 m from the walls, 1.5 m from the windows and between 1.2 m and 1.5 m above the floor. In such cases care should be taken to differentiate between ambient indoor noise levels attributable to sources such as air conditioning, and the noise source under consideration. g) For all noise measurements the axis of maximum sensitivity of the microphone must be directed towards the noise source. h) Non-steady noise: Where the noise is non-steady in nature, a longer sample period will be required to reflect all significant variations in the noise source. i) The level of the noise under assessment should be determined by measurement. If this is not practicable, for example where the source is not yet in operation, predictions may be undertaken. In such cases the method of calculation must be reported for approval and the reason for using calculations must be stated.

5) Information to be recorded

a) The following information should be recorded for audit and reporting purposes:

i) the date, time, address location of the measurements and the operator undertaking them;

ii) the type of instrumentation including the serial numbers of all elements of the measurement system and the calibrator used, the measurement procedure and any calculation used;

iii) the settings of the sound level meter

including the dynamic range, slow or fast response, etc;

iv) a description of the measurement location

including details of the nature of the ground between source and measurement position, i.e. acoustically hard or soft ground, if appropriate, the nature and form of any barriers between source and receiver, and the character of the ambient noise, including the identification of any significant noise sources other than the specific noise source under investigation;

v) a description of the time aspect of the

measurements. i.e. the reference and measurement time intervals, including details of sampling, if used;

vi) measurement positions including

microphone height above ground and distance from reflective surfaces if less than 3.5 m;

vii) where appropriate, a description of the

sound propagation model used; and

viii) the following conditions during the measurements should be described qualitatively and quantitatively where appropriate:

precipitation; wind speed and direction; presence of conditions likely to lead to

temperature inversion (i.e. clam nights with little cloud cover);

relative humidity; and variability and character of emission

noise sources. b) The Competent Agency for environmental protection will undertake regular inspections of facilities to enforce the standards set out by this document.

6) Measurement conditions a) Where possible maximum effort should be exercised in monitoring noise levels during meteorological conditions that are approximately consistent with the following:

i) wind speed between 1 and 5 meters per second measured at a height of 3 to 11 meters above the ground;

ii) wind direction within an angle of 45 of the direction connecting the dominant sound source and the centre of the specified measurement area;

iii) the wind direction is from the specific

noise source towards the noise receiver; iv) there should be no strong temperature

inversions near to the ground; and v) there should be no significant

precipitation.

b) Where measurement in such conditions is unavoidable, details of the adverse conditions should be recorded for information and additional measurements may need to be undertaken as appropriate. c) Where monitoring in difficult conditions is unavoidable, the Competent Agency must consider the impacts of these conditions upon the ability of the operator to comply with this standard. ,Compliance does however remain at the discretion of the Competent Agency.

d) For all measurements the microphone must be fitted with a wind shield as recommended to be appropriate by the manufacturer/supplier. Noise from wind acting directly on the microphone or on nearby structures or vegetation should not be permitted to interfere with the measurements.

7) Permitting

a) In circumstances where a facility, site or premises can provide substantive evidence that the prescribed noise limits are not practicable, a permit may be issued that allows the parameters within this standard to be temporarily exceeded. b) The permit application form in Appendix C must be completed in full and submitted to the Competent Agency within 60 days of the date of implementation. c) The Competent Agency may seek to externally verify any evidence provided within the application form. d) The Competent Agency will assess each application and issue a response on a case by case basis. e) Where rejected, the facility must meet the requirements of this standard or risk penalties as detailed in Article I. f) Where, accepted, a permit will be issued that may impose operating conditions, revised emission limits and a time-bound improvement schedule.

8) Noise abatement notices

a) Where the competent body is of the opinion that the level of noise recorded from a facility is excessive, it may issue a noise abatement notice. Such a notice will detail required abatement actions and may include the carrying out of works, which must be undertaken to reduce the noise levels. b) Abatement notices will be based on both physical and subjective assessments of the noise levels. The responsible authority may issue an abatement notice in circumstances where the level of noise does not exceed this standard. c) The requirements of an abatement notice may be variable in terms of timescales and specification. As a minimum, these requirements will be specified within the notice and must be fully complied with by the operator.

Article IV Community Noise

1) Definition

a) Community noise is defined as noise emitted from all sources except noise at the industrial workplace. It includes sources such as commercial premises (including restaurants, cafes and evening venues), ventilation systems, neighbours, sports events, transportation and light manufacturing processes in residential areas. b) For the purpose of this standard transportation sources are not included. Furthermore, for areas which are predominantly industrial in nature, for construction sites, (where an EIA has been required for the development) for motor vehicles and for equipment used outdoors, specific criteria are specified in Articles V and VI.

2) Permitted noise limits

a) The standards displayed in Table 2 are to be applied with regard to the level of free-field external noise, from noise emitting premises that is permitted in each of the area designations, A C. Each designation has a different permissible level to accommodate the variable levels of sensitivity and development / density pressure.

A = Sensitive These areas are designated quiet areas as they hold value in terms of them being places of worship, important tourist attractions, recreational park land and those areas surrounding hospitals, schools and noise sensitive natural habitats. B = Mixed Areas designated in this category will typically be dominated by residential properties

(including hostels and hotels) and may range from sparse population densities to suburban districts of cities. C = Non-sensitive This designation applies to mixed areas, often within cities where there is a mix of residential and commercial activities. This designation will also apply to retail and financial districts.

Table 2. Permitted free-field external noise limits for community noise, measured at any noise sensitive property within the appropriate area designation

LAeq,T(dB) Evening

LAeq,T (dB) Night

LAeq,T (dB)A 50 45 40 B 55 50 45 C 60 55 50

b) For a single noise emitting premises the noise levels in Table 2 shall pertain. In instances where there are two separate noise emitting premises the limits in Table 2 shall be reduced by 3dB (A) for each individual premises. For areas where there are more than two noise emitting premises the limits applied to each individual premises in Table 2 shall be reduced by 5 dB(A). c) Further to the permitted noise limits specified within Table 2 and in order to achieve a reasonable standard within habitable rooms at night, individual noise events during the night-time period (measured with the fast time-weighting) should not exceed 60dB LAmax at the nearest noise sensitive property. d) The noise level of an alleged excessive specific noise source must be measured at the closest boundary of the nearest noise sensitive property or noise sensitive open space. Where the most exposed faade is representative of the relevant boundary the measurements must be taken at a distance of 1m. Where a noise is alleged to be excessive the measurement should be made at a representative time of day. All relevant details of the measurement should be recorded and retained.

3) Noise sensitive properties adjoining the premises at which the source is situated

a) Where a noise sensitive property physically adjoins the premises at which the noise source is situated or has a blank wall facing the source, noise from any industrial or commercial source or from mechanical plant shall be at least 10dB(A) below the appropriate limit in Table 2. b) The sound level measurement shall be representative of the sound distribution within the habitable room of the noise sensitive property. The microphone shall be rotated in a sweeping motion

from a single axis. The rotation radius should be at least 0.7m and the plane of the traverse shall be inclined in order to cover a large proportion of the space. At no point should the microphone lie within 1m of a wall, floor or ceiling and the duration of the rotation shall be for not less than 15 seconds. c) Should other noise sources be audible within the room i.e. air conditioning, the aim should be for the residual noise level to be at least 10 dB(A) lower than the specific noise level. In cases where the difference is less than 10 dB(A) the specific noise level should be derived by logarithmic subtraction of the residual noise level from the measured total noise level with the source operating. d) Where a short term project may breach the attached standards i.e. during maintenance, repair, renovation, etc. the competent body must be approached in order to acquire a temporary permit which will be subject to conditions at the discretion of that competent body.

Article V Noise from industrial units in areas set aside primarily for industrial facilities.

1) Permitted noise limits Permitted noise limits

a) An occupier of industrial premises must not cause or permit excessive noise to be emitted from the premises. b) Noise emitted from industrial premises is considered excessive if the specific noise level at the nearest noise sensitive property or noise sensitive open space, exceeds the maximum permissible noise level for that time of day and the area in which the premises are situated. c) Industrial premises are split into four categories that must be determined by the operator but at the discretion of the Competent Agency: A1 Retail refers to areas that are entirely dominated by retail, dining and recreational properties. A2 Warehousing refers to areas where units predominantly store products or goods for distribution and there are no or very limited process activities. A3 Light industrial refers to those areas which may be mixed with or adjacent to residential properties where minor manufacturing processes take place. A4 Medium density industrial areas are those when a range of manufacturing processes including combustion take place on small to medium size sites and there is an absence of residential properties. A5 High density industrial refers to designated industrial cities and industrial complexes where large scale manufacturing, refining and petrochemical processes exist. Cement manufacture is specifically included. d) Permitted noise limits are contained in Table 3.

e) For a single noise emitting premises the noise levels in Table 3 shall pertain. For industrial/ commercial areas with occupation (actual or planned) by two separate significant noise emitting premises the limits in Table 3 shall be reduced by 3dB (A) for e individual premises. For areas where more than two industrial/ commercial premises exist or are planned the limits in Table 3 shall each be reduced by 5 dB(A) for individual premises. f) Further to the permitted noise limits specified within Table 3 and in order to achieve a reasonable standard within habitable rooms at night, individual noise events during the night-time period (measured with the fast time-weighting) should not exceed 70dB LAmax at the faade of the nearest noise sensitive property. g) In situations where general environmental noise is high (e.g. as a result of noise from extraneous sources, such as occasional passing cars), and when the noise being investigated is steady in nature, the specific noise may be assessed by measurement of the LA90,T background noise. For the specific noise to be suitable for assessment using the LA90,T, it must be a constant and steady noise with no variation over the time period being assessed (i.e. day, evening or night). In such a case the measured LA90,T specific noise may be considered to be equivalent to the LAeq,T and the assessment made on the basis that it is so. That a measured LA90,T has been used rather than a measured LAeq,T must be noted in the measurement and assessment records (Art. II, (5)). h) Where the industrial noise operates continuously, such that it is not possible to measure the ambient noise level in the absence of the source, ambient noise measurements should be undertaken at a representative location which is not influenced the industrial noise source under consideration. In such cases the reason for assuming that the location is representative should be noted. i) For sensitive properties adjoining the premises at which the source is located (Art IV, (3)).

Article VI Noise from construction activities 1) Basic conditions

a) Construction activities contribute significantly to noise disturbance particularly through activities such as percussive piling, the general use of heavy machinery on site and heavy traffic both on and off site. Close proximity to residential areas and other sensitive receptors during some construction projects results in a significant risk of major disturbance. Construction activities in certain areas must therefore be controlled carefully. b) The general noise emission limits for permissible construction noise levels at sites where an EIA has been required are set out in Table 4. These levels represent the maximum values that are acceptable during construction activities in the designated areas A D. c) Where, through the Environmental Impact Assessment (EIA) process for a project, it has been predicted that the limits in Table 4 are likely to be breached a construction noise permit will be required.

d) Where in the opinion of the Competent Agency, a project is deemed to provide significant social benefit and where the application of these construction noise standards will cause excessive cost or disruption to the realisation of that social benefit, the Competent Authority may issue a conditional exemption permit which displays due consideration to these factors for permanent or temporary construction activities.

2) Permissible noise levels

a) Receptors are classified as follows: A = Quiet areas These areas are designated quiet areas as they hold value in terms of them being places of worship, important tourist attractions, recreational park land and those areas surrounding hospitals, schools and noise sensitive natural habitats. B = Sensitive Areas designated in this category will typically be dominated by residential properties (including hostels and hotels) and may range from sparse population densities to suburban districts of cities. C = Mixed This designation applies to mixed areas, often within cities where there is a mix of residential and commercial activities. This designation will also apply to retail and financial districts. D = Non-sensitive The final classification of district is a predominantly industrial area where there are few residential properties and commercial premises. This classification also applies to industrial cities and land that is generally unpopulated.

3) Dispensations

a) In circumstances where the occupier of a premises, or anyone undertaking work there, either directly or indirectly on behalf of the occupier, becomes aware of the need for a temporary dispensation from any of the noise limits required by this standard they may apply to the Competent Agency for consent. Such an application must be made in writing at least 14 days prior to the date from which the dispensation is required. Sufficient information must be provided at the time of the application detailing:

i) a description of the works for which it is required;

ii) the necessity for the dispensation; iii) its timing and duration; iv) the methods to be employed for

minimising noise during the period of the dispensation; and

v) the contact details for the occupiers

controller of the work (relevant at all times for the periods during which the work is to take place).

b) Where any of the specified information is missing or inadequate, the Competent Agency may seek such further information as it may reasonably require to determine the application and will not be obliged to permit the dispensation by the date sought in the application. c) In case of a breach of the noise limits in this standard arising from an unforeseen emergency that risked injury or physical damage to persons or plant, the circumstances of the incident must be reported to the Competent Agency retrospectively. Such notification must be in writing and submitted to the Competent Agency within 24 hours of the occurrence of the incident. The following details must be provided with the notification:

i) the emergency that resulted in a breach of the noise limits;

ii) the date, timing and duration of its

occurrence; iii) the steps taken to prevent a recurrence;

and

iv) the contact details for the occupiers controller of the work.

Article VII Noise from vehicles 1) General provisions

a) Mobile noise sources, particularly motorcycles and vehicles, are significant contributors to ambient noise levels and environmental noise problems. The appropriate silencing of motorcycles and vehicles represents the key method by which this problem can be addressed. b) This schedule applies to all vehicles with a date of manufacture on or after DD/MM/YY. c) The maximum permissible noise levels for motorcycles and vehicles are set out below in tables 5 and 6 respectively. These limits represent the maximum levels of noise that are acceptable from the defined classification of motorcycles and vehicles. d) There are two assessment methods both of which should be applied to each individual motorcycle or vehicle: the moving noise level and the stationary noise level. See methods in Schedules 4 and 5 respectively.

3) General measurement provisions

a) Measurements shall be made on unloaded vehicles in a sufficiently silent and open area (ambient noise and wind noise at least 10 dB(A) below the noise being measured).

b) For all tests the relevant motorcycle/vehicle must be unladen and, except in the case of non-separable vehicles, without trailer or semi trailer. For vehicles, if the vehicle is fitted with more than two-wheel drive, it shall be tested in the drive which is intended for normal road use and for motorcycles having more than one driven wheel, only the drive provided for normal road operation may be used.

c) For all tests the test area shall be dry, practically level and surfaced with concrete, asphalt or a similar material.

d) For all tests the measurements shall be considered valid if the difference between two consecutive measurements on the same side of the motorcycle/vehicle does not exceed 2 dB(A). The maximum figure recorded shall constitute the result of the measurement.

4) Measurement Procedure Moving vehicle/motorcycle

a) The measurement area shall take the form of an open space of 50 meter radius for vehicles and a 25m radius for motorcycles. The central part of the open space should have a radius of at least 20 meters. b) No person other than the observer taking the readings from the apparatus and the driver/rider may remain near the vehicle or the microphone, as the presence of spectators near either the vehicle or the microphone may considerably affect the measurement results.
