Noise Mapping Scotland - Round 4 - Railway (major rail sources) - LAeq16h
Noise maps showing areas that are relatively louder or quieter, measured in decibels (dB), for major railway traffic noise in Scotland in 2021. Major railways are defined as those with more than 30,000 train passages per year. The data represents the 16-hour daytime level (LAeq,16h) - the A-weighted equivalent continuous sound level over a 16-hour time period (07:00-23:00). Scottish Ministers commissioned strategic noise mapping analysis to meet the requirements of the Environmental Noise Directive (Directive 2002/49/EC), which is legally implemented in Scotland thorough the Environmental Noise (Scotland) Regulations 2006, as amended by the Environmental Noise (Scotland) Amendment Regulations 2018. Noise maps are used to identify areas where noise levels are high and, by linking population data, estimate how many people are affected. This aids in the production of noise action plans to manage noise and reduce noise levels where appropriate.

The Environmental Noise Directive requires, on a five yearly cycle, the Scottish Government to produce strategic noise maps. The Directive was transposed into Scottish legislation under the Environmental Noise (Scotland) Regulations 2006 and amended by the Environmental Noise (Scotland) Amendment Regulations 2018 following the United Kingdom’s exit from the European Union. Strategic noise maps for the fourth round of mapping have been produced using the European Commission’s common noise assessment methods (CNOSSOS-EU). This is a new method of producing strategic noise maps for the entirety of Scotland, meaning the previous three rounds are not comparable to this round. The analysis was completed using several in house, open source, and commercially available software tools, and was delivered by Noise Consultants Limited in collaboration with Mott MacDonald, Acustica and Stapelfeldt on behalf of the Scottish Ministers. The maps were created using specialised noise modelling software, which calculates the noise level on a 10m grid at a reception height of 4m above local ground level as required by the Environmental Noise Regulations. The software takes account of physical features such as buildings and the ground contours. The grid information is then used to create the series of noise contour bands, depicting an average noise level for an average day in the year. The data required for the calculations of noise levels have been determined by consultation with various organisations including Transport Scotland, SEPA, Network Rail, Airport Operators, Local Authorities, and others. For Round 4, the following noise sources were included: • Airports with more than 50,000 (fifty thousand) movements; • Airports with less than 50,000 (fifty thousand) movements but emit relevant noise levels into agglomerations; • Railways - both major (with more than 30,000 (thirty thousand) train passages a year) and non-major railways; • Roads - both major (with more than 3,000,000 (three million) vehicle passages per year) and non-major roads; • Industry within qualifying agglomerations (urban areas with populations in excess of 100,000 (one hundred thousand), i.e. Aberdeen, Dundee, Edinburgh, Falkirk and Glasgow). Results were produced for roads (both all sources and major roads only), rail (both all sources and major railways only) and industry using the following indicators: • Day-evening-night level (Lden) - the annual average noise level with separate weightings for the evening and night periods. Day, evening and night periods are defined as 07.00 to 19.00, 19.00 to 23.00 and 23.00 to 07.00 respectively; • Daytime level (Lday) - the annual average A-weighted long-term sound over the daytime period (07:00-19:00); • Evening level (Leve) – the annual average A-weighted long-term sound over the evening period (19:00-23:00); • Night level (Lnight) – the annual average A-weighted long-term sound over the night period (23:00-07:00); • 6-hour night-time level (LAeq,6h) - the A-weighted equivalent continuous sound level over a 6-hour time period (24:00-06:00). It is the sound level of a steady state sound that has the same energy as a fluctuating sound over the same period; • 16-hour daytime level (LAeq,16h) - the A-weighted equivalent continuous sound level over a 16-hour time period (07:00-23:00). It is the sound level of a steady state sound that has the same energy as a fluctuating sound over the same period; • 18-hour daytime level (LAeq,18h) - the A-weighted equivalent continuous sound level over a 18-hour time period (06:00-24:00). It is the sound level of a steady state sound that has the same energy as a fluctuating sound over the same period. Consolidated results were also produced including outputs from each of the road, rail, industrial and airport noise grids. The consolidated maps are produced simply as a logarithmic sum of the separate source sound levels and are not subject to response or effects based corrections.
