Regulation 5
1.—(1) The values of Lden, night and the supplementary noise indicators shall be determined by computation (at the assessment position).
(2) In this Schedule–
“assessment position” means the assessment height in paragraph 7 of Annex IV to the Directive; and
“Recommendation” means Commission Recommendation 2003/613/EC of 6th August 2003 concerning the guidelines on the revised interim computation methods for industrial noise, aircraft noise, road traffic noise and railway noise, and related emissions data(1).
2. For road traffic noise indicators the assessment method “Calculation of road traffic noise” (Department of Transport, 7th June 1988, HMSO)(2) shall be used, adapted using the report “Method for converting the UK road traffic noise index LA10,18h to the EU noise indices for road noise mapping” (DEFRA, 24th January 2006)(3).
3. For railway noise indicators the assessment methods–
(a)“Calculation of railway noise” (Department of Transport, 13th July 1995, HMSO)(4); and
(b)(in relation to railways to which it is expressed to apply) “Calculation of railway noise 1995 Supplement No. 1 Procedure for the calculation of noise from Eurostar trains class 373” (Department for Transport, 20th October 1996, Stationery Office)(5),
shall be used, adapted as shown in Figure 6.5 of the report “Rail and wheel roughness – implications for noise mapping based on the Calculation of Railway Noise procedure” (DEFRA, March 2004)(6).
4. For aircraft noise indicators the assessment method “Report on Standard Method of Computing Noise Contours around Civil Airports” (Second Edition, European Civil Aviation Conference, 2 3 July 1997)(7) shall be used in accordance with paragraph 2.4 of the Annex to the Recommendation.
5.—(1) For industrial noise indicators and port noise indicators the propagation assessment method described in “ISO 9613 2:1996 Acoustics – Attenuation of sound during propagation outdoors – Part 2: General method of calculation” (International Standards Organisation, 1996)(8) shall be used in accordance with paragraph 2.5 of the Annex to the Recommendation.
(2) Suitable noise emission data (input data) for “ISO 9613 2:1996 Acoustics – Attenuation of sound during propagation outdoors – Part 2: General method of calculation” can be obtained either from measurements carried out in accordance with one of the following methods:
(a)“Acoustics. Determination of sound power levels of multisource industrial plants for evaluation of sound pressure levels in the environment. Engineering method” (BS ISO 8297:1994, British Standards Institute)(9);
(b)“Acoustics. Determination of sound power levels of noise sources using sound pressure. Engineering method in an essentially free field over a reflecting plane” (BS EN ISO 3744:1995, British Standards Institute)(10);
(c)“Acoustics. Determination of sound power levels of noise sources using sound pressure. Survey method using an enveloping measurement surface over a reflecting plane” (BS EN ISO 3746:1996, British Standards Institute)(11),
or by using Toolkit 10 of the “Good Practice Guide for Strategic Noise Mapping and the Production of Associated Data on Noise Exposure Version 2, Position Paper Final Draft” (European Commission Working Group Assessment of Exposure to Noise, 13th January 2006)(12).

Y Diweddaraf sydd Ar Gael (diwygiedig):Y fersiwn ddiweddaraf sydd ar gael o’r ddeddfwriaeth yn cynnwys newidiadau a wnaed gan ddeddfwriaeth ddilynol ac wedi eu gweithredu gan ein tîm golygyddol. Gellir gweld y newidiadau nad ydym wedi eu gweithredu i’r testun eto yn yr ardal ‘Newidiadau i Ddeddfwriaeth’.
Gwreiddiol (Fel y’i Deddfwyd neu y’i Gwnaed): Mae'r wreiddiol fersiwn y ddeddfwriaeth fel ag yr oedd pan gafodd ei deddfu neu eu gwneud. Ni wnaed unrhyw newidiadau i’r testun.
Mae Nodyn Gweithredol yn nodi datganiad byr o ddiben Offeryn Statudol yr Alban ac yn rhoi gwybodaeth am ei amcan polisi a goblygiadau polisi. Ei nod yw gwneud yr Offeryn Statudol yr Alban yn hygyrch i ddarllenwyr nad oes ganddynt gymhwyster cyfreithiol ac maent yn cyd-fynd ag unrhyw Offeryn Statudol yr Alban neu Offeryn Statudol Drafft yr Alban a gyflwynwyd yn fanwl gerbron Senedd yr Alban o Orffennaf 2005 ymlaen.
