Noise pollution maps are tools that provide an overview of noise levels in a given area. They are often used to track transportation-related noise and facilitate decision-making for stakeholders, researchers, and policymakers. These maps are based on noise modelling and data from various sources, such as flight information, airport traffic statistics, and community-contributed data. They can be used to estimate noise exposure at a national, state, or county level, aiding in health impact assessments and noise-related transportation investments. Additionally, noise pollution maps can help individuals understand the noise environment in their desired geographic locations. While these maps offer valuable insights, they are intended for tracking trends and should not be solely relied upon for evaluating noise levels at specific locations or times.

What You'll Learn
Transportation noise maps
One notable example is the National Transportation Noise Map, developed by the Bureau of Transportation Statistics (BTS). This map serves as a valuable resource for USDOT stakeholders, researchers, industry professionals, and the public. It enables users to track trends in transportation-related noise by mode and across multiple transportation modes simultaneously. By overlaying transportation noise data with population information, the map facilitates the assessment of the number of people exposed to different levels of noise. This information is crucial for health impact assessments and environmental justice studies.
The National Transportation Noise Exposure Map is another powerful tool created by combining the BTS's National Transportation Noise Map with population data from the Census Bureau's American Community Survey. This map provides estimates of the number and proportion of the population exposed to different noise levels, categorized into ranges such as LAeq 45-50 dB, 50-60 dB, and so on. For instance, the map revealed that approximately 94.9 million people (29.1% of the US population) were exposed to ≥45 dB LAeq of transportation-related noise in 2020.
These transportation noise maps have significant implications for policy and planning. They guide policymakers and planners in prioritizing noise-related transportation investments and making informed decisions to mitigate noise pollution. The maps also enable the public to gain insights into potential noise exposure in their communities. However, it's important to recognize that these maps are designed for tracking trends, and they may not accurately reflect noise levels at specific locations or times due to various assumptions and limitations in the modeling process.
Additionally, transportation noise maps often consider noise contributions from multiple sources, such as aviation, road, and rail. However, it's worth noting that certain transportation sources, like helicopters and maritime vessels, as well as non-transportation sources such as construction sites and power plants, are not always included in the analyses. These maps continue to evolve, with future versions expected to incorporate additional noise sources for a more comprehensive understanding of transportation noise pollution.

Noise pollution health risks
Noise pollution is one of the most ubiquitous environmental pollutants, and it poses a significant threat to both physical and mental health. Environmental noise is one of the leading environmental risks for physical and mental health and well-being, contributing to a high burden of disease. Noise pollution can lead to several health issues, and the risk increases with prolonged exposure.
Sources of noise pollution include transportation, such as road traffic, aviation, and railways, as well as industrial noise and amplified music in leisure activities. Noise levels can vary depending on factors like time of day and season. Noise maps, such as the National Transportation Noise Map, are used to track trends in transportation-related noise and help policymakers and planners prioritize noise-related investments.
The health risks associated with noise pollution are well-documented. Research has linked noise exposure, particularly from traffic, to various mental health conditions, including depression, anxiety, bipolar disorder, and behavioural problems in children and adolescents. There is also evidence of potential adverse effects on the central nervous system, with reports of neuroinflammation and cerebral oxidative stress. Additionally, noise pollution can cause sleep disturbances and annoyance, impacting overall well-being.
Noise pollution has also been associated with cardiovascular health risks. Studies have suggested a link between noise exposure and an increased risk of cardiovascular ailments, such as stroke. Furthermore, noise can contribute to other physical health issues, including hearing impairment and tinnitus.
To protect against the harmful effects of noise pollution, individuals can take measures such as using hearing protection like earplugs or earmuffs when exposed to loud noises. Additionally, authorities and policymakers can develop and implement noise reduction measures, following guidelines such as the WHO's "Environmental noise guidelines for the European Region", to minimize the impact of noise pollution on public health.

Real-time noise mapping
Noise pollution is a growing concern for many people, and noise mapping is one way to address this issue. Real-time noise mapping is a developing field that aims to provide dynamic and accurate representations of noise levels in a given area. This technology has a wide range of applications, from transportation noise monitoring to video tone mapping.
One example of real-time noise mapping is the National Transportation Noise Map, which tracks trends in transportation-related noise. This map allows users to view potential exposure to aviation, highway, and rail noise at both the national and county levels. The data provided by this map helps policymakers and planners prioritize noise-related transportation investments and understand the potential impact of different scenarios. However, it is important to note that this map is designed for tracking trends and may not accurately represent noise levels in specific locations or at particular times.
Another tool for real-time noise mapping is the dBmap.net Noise Mapping Tool, which models external sound propagation and calculates decibel levels from sources of environmental and industrial noise. This web application is based on the calculations of ISO-9613 and allows users to create interactive models that are freely accessible. The tool considers the screening effects of buildings and barriers, providing a more accurate representation of sound propagation in a given area.
In addition to these tools, there are also mobile applications such as NoiseCapture, which crowdsource data to create a global noise map. This map provides a comprehensive view of the noise environment worldwide, allowing users to explore noise levels in different regions.

Audible data-visualisation maps
Maps have long been used to understand proximity and navigate, but with technological advancements, they have become digital, interactive, and more appealing for data analysis and reporting. Audible data visualisation maps are a type of data visualisation that represents data through sound, allowing users to perceive information by listening instead of seeing.
One example of an audible data visualisation map is the "Noisy City" project and the Brussels noise pollution map, which help identify and address real-world problems. Another example is the National Transportation Noise Map, which facilitates USDOT stakeholders, researchers, industry, and the public in tracking trends in transportation-related noise. The map provides a basis for understanding what-if scenarios and helps policymakers and planners prioritise noise-related transportation investments. The data can be viewed at the national, state, or county level and includes simplified noise modelling. However, it is important to note that this map is intended for tracking trends and should not be used to evaluate noise levels in specific locations or at specific times.
There are also other interactive map data visualisations that utilise location data and maps. For instance, Justin Fung created an interactive map that shows the mini-migration during a single day using data from the 2010 Census, the MTA's turnstile database, and a previous NYU study. The map depicts hourly changes throughout the week, with bars representing population density in different areas of Manhattan. Similarly, Alexander Waleczek analysed public holidays around the world and developed an interactive map that shows where a different holiday is held each day of the year.
In addition to interactive maps, other types of data visualisations such as heat maps can also be effective in comprehending large volumes of complex statistical data. For example, a heat map was used to compare teams and players in the 2018 World Cup tournament, combined with player ratings from FIFA 18. This allowed fans to see how players at each position stacked up against their competitors. Density Design Lab's "After Babylon" is another example of an interactive map that visualises the world's 2,678 living languages, showing their origins, where they are spoken, and the percentage of the world's population that speaks them.

Noise mapping limitations
Noise mapping is a tool used to create detailed representations of noise levels in a given area, helping to identify noisy areas. It is an essential technique for industries, construction sites, and urban planners to adhere to legal noise limits set by environmental agencies. Noise mapping can also help evaluate noise levels in factories, warehouses, and industrial zones, ensuring compliance with regulatory limits.
However, noise mapping has its limitations. Firstly, it is designed for national-level analysis and trend tracking, and may not accurately represent noise levels in specific locations or at particular times. For instance, the National Transportation Noise Map, which helps stakeholders and policymakers understand transportation-related noise, should not be used to evaluate noise levels in individual locations. Similarly, the Pisa Noise Mapping Project in Italy, which aimed to map road traffic noise, had uncertainties due to the modelling methods used.
Another limitation of noise mapping is the potential for overestimation or underestimation of noise levels due to the assumptions made in the analysis. For instance, the National Transportation Noise Map does not consider shielding from barriers or terrain, which may result in overestimated noise levels in certain areas. Additionally, noise mapping may not account for dynamic factors such as time of day, season, or specific vehicle types, which can influence actual noise exposure.
Furthermore, noise mapping studies can be resource-intensive and time-consuming, requiring specialized equipment and expertise. The quality and accuracy of noise mapping can also vary depending on the data sources and modelling complexity. As a result, noise mapping may not always be feasible or accessible for all communities, particularly in smaller areas or developing regions.
Despite these limitations, noise mapping remains a valuable tool for identifying noisy areas, ensuring regulatory compliance, and informing noise reduction strategies. With advancements in technology, such as IoT-powered sensors and AI-driven analytics, noise mapping is becoming more sophisticated and integrated into real-time monitoring systems, enabling dynamic responses to noise pollution.
