Noise pollution is a serious issue affecting millions of people worldwide. It is caused by machines, transport, and propagation systems, with traffic noise being the predominant source in urban areas. The World Health Organization (WHO) defines noise above 65 decibels (dB) as noise pollution, and it becomes harmful when it exceeds 75 dB. This pollution has significant impacts on human health, including cardiovascular disorders, hypertension, high stress levels, tinnitus, hearing loss, and sleep disturbances. It also affects wildlife, interfering with breeding cycles and communication, and threatening ecosystems. The economic cost of noise pollution is substantial, with estimates of up to $5 trillion USD annually in healthcare expenses, lost productivity, and decreased property values. This amount is comparable to the social cost of urban road noise in England, which is estimated to be between £7 billion and £10 billion annually.

Noise pollution is a serious issue affecting millions of people worldwide. It has been identified as the second largest environmental health risk in Western Europe by the World Health Organization (WHO). The social cost of road noise in England alone is estimated at £7-£10 billion annually, a figure comparable to the cost of road accidents and significantly greater than the impact of climate change. This estimate considers the impact of noise on health, wellbeing, productivity, and the environment.
Noise pollution has been linked to various health problems, including hearing loss, cardiovascular diseases, stress-related conditions, and sleep disturbances. The financial burden of treating and managing these health issues is significant. For example, the European Environment Agency estimates that noise pollution causes 12,000 premature deaths and 48,000 new cases of ischaemic heart disease annually in Europe. Additionally, constant noise can lead to stress, lack of concentration, and reduced overall work efficiency, impacting productivity in workplaces and educational institutions.
The impact of noise pollution on the environment is also significant. It can disturb wildlife, alter bird breeding patterns, and damage sensitive ecosystems. For example, noise from global shipping can be reduced by physically isolating engines from metal hulls and shaping propellers to reduce shock waves in the water. Additionally, rural areas can experience noise pollution from agricultural activities, industrial operations, transportation, and natural sounds.
To address noise pollution, various tools and methods have been developed to estimate and reduce noise exposure. These include economic valuation tools, noise modelling tools, and sensitive indicators for road, rail, and aircraft noise. Additionally, interventions such as low-noise pavement, quiet tire design, traffic calming measures, and noise barriers have been proposed to reduce noise levels in urban areas.
The social cost of road noise in England, estimated at £7-£10 billion annually, highlights the significant impact of noise pollution on society and the economy. It is essential to fully consider the impacts of noise when making decisions, policies, or programmes to mitigate these negative consequences.

Noise pollution's impact on human health, including heart disease, high blood pressure, and cognitive issues
Noise pollution is the spread of unwanted sounds into the environment, and it can come from natural sources, such as birdsong, or from human activity, such as vehicle traffic. While it is often overlooked as a health hazard, noise pollution can have a significant impact on human health and well-being.
The World Health Organization (WHO) identified environmental noise as the second largest environmental health risk in Western Europe. It is estimated that the annual social cost of urban road noise in England is £7 billion to £10 billion, a magnitude similar to that of road accidents. Unfortunately, the effects of noise on night noise, school performance, and the value of quiet areas have not been fully quantified.
Noise pollution has been linked to an increased risk of cardiovascular events and disease. Studies have found that noise exposure can trigger stress responses in the body, leading to increased blood pressure and hypertension. Specifically, nighttime aircraft noise has been shown to impair endothelial function and increase blood pressure in patients with or at high risk for coronary artery disease. Evidence suggests that interventions to reduce noise and air pollution can alleviate these blood pressure increases, supporting a causal link. In addition to hypertension, noise pollution has been associated with atherosclerotic cardiovascular disease, with clinical studies providing clear evidence of this link.
Noise pollution can also impact cognitive abilities, particularly in middle-aged and older adults. There is evidence that higher residential noise exposure is associated with a higher risk of cognitive impairment in people aged 45 and above. Additionally, studies have found an association between aircraft noise and reading and language abilities in children, with children in quieter classrooms having higher reading comprehension scores.
Overall, noise pollution has been shown to have significant impacts on human health, including an increased risk of heart disease, high blood pressure, and cognitive issues. While the exact monetary value of these impacts is challenging to assess, the social cost of noise pollution is substantial, emphasizing the importance of considering noise impacts in policy decisions.

Environmental impact and damage to wildlife, including bird breeding patterns and sensitive ecosystems
While there is no clear figure on how much is spent on noise pollution, the annual social cost of urban road noise in England alone is estimated to be between £7 billion and £10 billion. This is a significant amount, highlighting the economic impact of noise pollution.
Noise pollution has been identified as an emerging threat to species and ecosystems, with potential harm to the persistence of many species. Birds, in particular, are affected by noise pollution, which can alter their breeding patterns and disturb their nesting habits. A study by biologists at California Polytechnic State University found that light pollution caused birds to start nesting earlier than normal, with the timing depending on the type of environment. Noise pollution was found to delay nesting for birds with lower-frequency songs, as these songs are harder to hear through low-frequency human noise.
In addition to birds, other taxonomic groups such as mammals and fishes have been studied regarding the effects of noise pollution. However, there is less knowledge about the impacts on certain species, such as amphibians, reptiles, and invertebrates, and the effects of specific types of noise like recreational and military noise.
The impact of noise pollution on ecosystems is also a growing area of research. While there has been some focus on the disturbances caused by noise to humans, public policies for biodiversity conservation are expected to increasingly address this issue. For example, the European Commission's Green Paper on Future Noise Control Policy in 1996 addressed noise pollution from an environmental protection perspective. Similarly, France's Environmental Code includes provisions against disturbances due to noise that harm the environment.
Overall, noise pollution can have significant environmental impacts, including altering bird breeding patterns and disturbing wildlife in sensitive ecosystems. While the exact monetary value of these impacts has not yet been determined, they are expected to be substantial, and addressing them through research and policy will be crucial in the coming years.

The cost-benefit analysis of noise control measures, such as low-noise pavement and sound barriers
Noise pollution has a significant impact on human health, wildlife, and the environment. Research has linked noise to various ailments, including heart disease, high blood pressure, and sleep disturbances. The World Health Organization (WHO) identified environmental noise as the second-largest environmental health risk in Western Europe. The social cost of urban road noise in England is estimated at £7-10 billion annually, emphasizing the importance of considering noise impacts in policymaking.
To address noise pollution, various control measures have been proposed, including low-noise pavement and sound barriers. Low-noise pavements aim to reduce noise by modifying surface characteristics, while sound barriers are constructed to protect nearby residents from excessive noise levels. The cost-benefit analysis of these measures is essential for determining their effectiveness and feasibility.
Low-noise pavements offer a promising solution to mitigate noise pollution. According to Nijland et al. (2003), low-noise pavements are cost-effective, even if their effectiveness is lower than that of low-noise tires. The acoustic performance of pavement is influenced by factors such as porosity, resistivity, and tortuosity. However, there are challenges in implementing low-noise pavements due to the lack of acceptance tests and incentives for state or local agencies to adopt them. Additionally, the noise reduction from quieter pavements tends to degrade over time, requiring rehabilitation.
Sound barriers, also known as noise barrier walls, are a widely adopted noise abatement measure. The cost-effectiveness of sound barriers is typically expressed in terms of CPBR (cost per benefited receptor) or APBR (allowable barrier area per benefited receptor). The cost per benefited receptor varies across different states and is influenced by factors such as the number of benefited receptors and the unit cost of the barrier. Sound barriers provide significant noise reduction for a limited number of nearby residences and are considered an eyesore by some residents.
In conclusion, the cost-benefit analysis of noise control measures, such as low-noise pavement and sound barriers, involves weighing the costs of implementation against the expected noise reduction and societal benefits. While low-noise pavements offer a promising solution, challenges remain in ensuring their durability and incentivizing their adoption. Sound barriers, despite their high cost and limited coverage, are currently favored by policies like FHWA guidelines. Further research and policy developments are needed to fully incorporate the benefits of quieter pavements into cost-benefit analyses and promote their implementation.
