Noise pollution is an issue that has been around for a long time, with complaints about noise dating back to the 1920s and 30s in New York City. However, it was not until the 1970s that noise was perceived as an environmental threat. Noise pollution can be considered a negative externality, which is an economic term referring to a cost incurred by a third party with no control over how that cost was created. In the case of noise pollution, the social costs of production exceed the private costs, and these external costs are often borne by society in the form of health issues, reduced property values, and negative impacts on wildlife habitats. Governments and companies can address these externalities through financial and social measures, such as taxation and regulation, to reduce the negative impact on society.

Historical noise complaints in NYC
Noise pollution has long been a concern for New Yorkers, with the city's noise levels averaging 85 decibels, far exceeding the World Health Organization's standard for daytime noise, which is 55 decibels. The issue has been exacerbated by the increase in individuals' ability to create amplified noise and the difficulty of escaping the city's noise due to its ability to travel and penetrate materials.
The New York City Noise Code sets standards for acceptable noise levels at different times of the day, and both the New York City Department of Environmental Protection (DEP) and the New York City Police Department (NYPD) share responsibility for reducing excessive and unreasonable prohibited noises. The determination of what constitutes excessive noise is based on sound level (dBA), distance from the sound, time of day, and duration, with specific duration limits for animal noises that change with the time of day.
Noise complaints are a frequent issue in New York City, with over 99.8 billion complaints made in 2019 alone. Common sources of complaints include loud music or television, late-night gatherings, pet noise, and construction noise. These complaints often lead to disputes between neighbours or with landlords, and tenants have the right to live in an environment reasonably free from excessive noise. Landlords are expected to address legitimate noise complaints and ensure tenants' peaceful living environment, and tenants can withhold rent or file a complaint with city authorities if the landlord fails to take action.
To address the noise issue, New Yorkers have employed various strategies, such as using earplugs and noise-cancelling headphones, soundproofing their homes, and joining community action groups like SONYC to strengthen their voices. Additionally, the "Stop Spreading the Noise" Act was passed by the New York City Council in December 2023, aiming to crack down on loud vehicles and construction-related noise. Despite these efforts, escaping the city's noise remains a challenge, and it continues to impact the quality of life for many residents.

The economic definition of an externality
Externalities are often considered market deficiencies, and they can impact the consumption and production opportunities of unrelated third parties. The price of a product typically does not include the externalities, creating a gap between the gains or losses of private individuals and society as a whole. For example, in the case of pollution, a traditional example of a negative externality, a polluter may only consider the direct costs and profit opportunities from production without taking into account the indirect costs to those harmed by the pollution. This failure to internalize external costs can result in market failure, as it leads to differences between private and social costs or returns.
To address negative externalities, governments and institutions often intervene to internalize externalities through financial and social measures. One common approach is to impose taxes on the producers of negative externalities, known as "Pigovian taxes," which aim to align private costs with social costs. Governments may also subsidize those who generate positive externalities, providing incentives for socially beneficial activities. Market-driven approaches can also be used to correct externalities, such as through contractual bargaining between affected parties.
Noise pollution is considered a negative externality, as it imposes costs on third parties who did not choose to incur them. For example, in the 1920s and 1930s, residents of New York City experienced noise pollution from various sources, including car horns, construction, and factories, leading to complaints and concerns about the environmental and health impacts. This noise pollution created external costs, such as potential hearing loss and an unsafe environment, which were not considered in the production or consumption decisions that created them.

Negative externalities and market failure
Noise pollution is a negative externality, which occurs when the cost to society of an economic agent's action is greater than the cost to the agent. In other words, there are external costs that are not compensated for. For example, in the 1920s and 1930s, New Yorkers experienced noise pollution from ice deliveries, boat whistles, car horns, and construction. Similarly, in 1932, a Brooklyn resident wrote to the NYC Noise Abatement Commission complaining about noise from a nearby pickle factory.
Negative externalities can also be generated during the production or consumption of a good or service, impacting unrelated third parties. For instance, the production of refrigerators creates pollution as a byproduct, imposing costs on society through injuries to human health, property values, wildlife habitats, and reduced recreation possibilities. These externalities are considered market deficiencies, leading to calls for government intervention through taxation and regulation.
When firms do not account for all costs incurred in the production of output, it results in market failure. In the case of pollution, the social costs of production exceed the benefits to consumers, leading to overproduction. If firms were required to pay the social costs of pollution, they would create less pollution but produce fewer goods at a higher price. This can be illustrated using a demand and supply diagram, where the supply curve shifts to reflect the additional external costs of pollution, resulting in a higher price, lower production, and reduced pollution.
To address negative externalities, governments can impose the cost of externalities on the producer through legislation. Firms can then pass these costs on to consumers by increasing the price of their goods or services. However, this approach may not always be effective, as firms operating in markets without anti-pollution restrictions may still dispose of waste freely. As a result, it is essential for companies to be mindful of their entire production process and the potential residual impacts on the environment.

How to calculate social costs
Noise pollution is a negative externality, which means that it incurs costs on society that are greater than the costs to the individual creating the noise. These costs can be calculated and broadly fall into economic, social, and health categories.
Firstly, it is important to identify the sources and types of noise pollution. This could be road, rail, or aviation noise, or noise from industrial zones and busy traffic. Once the source is identified, the next step is to determine the negative externality, which in this case, is the increase in noise pollution.
The social costs of noise pollution can be calculated by considering the following factors:
- Health: Noise pollution is associated with a range of health issues, including heart attacks, strokes, and dementia, hearing loss, cardiovascular diseases, and stress-related conditions. The World Health Organization (WHO) estimates that approximately one million lives are lost every year due to exposure to environmental noise. The costs of treating these health issues can be quantified and included in the social cost calculation.
- Productivity: Noise can negatively impact productivity through distraction, fatigue, and interruption of communication. For example, research has shown that people living near airports or busy roads report higher frequencies of headaches, take more sleeping pills, and are more prone to accidents due to fatigue. These factors can lead to reduced productivity in the workplace, and the resulting economic impact can be calculated.
- Environment: Noise can have a significant impact on the natural environment, such as altering bird breeding patterns, disturbing wildlife, and damaging sensitive ecosystems. While these impacts may be challenging to quantify in monetary terms, they still represent a social cost that should be considered.
- Amenity: This refers to the conscious displeasure of those exposed to the noise, including sleep disturbance, annoyance, and the loss of property value. Sleep disturbance, for instance, can impair memory, creativity, judgment, and psychomotor skills. These impacts can be valued and included in the calculation of social costs.
- Quality of Life: Noise pollution can disproportionately affect disadvantaged communities, leading to social isolation, decreased community engagement, and increased stress, anxiety, and irritability. These impacts on quality of life can be considered in the social cost calculation.
To calculate the social costs of noise pollution, various tools and models can be utilized, such as the Transport Noise Modelling Tool provided by the UK government. This tool helps to estimate the marginal costs associated with increases in transport noise above baseline values. Additionally, the Webtag Guidance provided by the Health Protection Agency offers a framework for quantifying the impacts of noise for transport schemes. By using these tools and considering the range of impacts noise pollution has on society, a comprehensive calculation of social costs can be achieved.

Solutions to noise pollution
Noise pollution, an unwanted and unpleasant sound that can cause stress, sleep disturbances, and other harmful effects on human health, is indeed a negative externality. It is an issue that affects people's well-being and quality of life, often arising from various economic activities and everyday life. Here are some detailed solutions to tackle noise pollution:
Noise Barriers and Absorption: Installing noise barriers, such as sound-absorbing walls or fences, can be an effective way to block or absorb sound waves and reduce the impact of noise pollution. These barriers are particularly useful in urban areas, near highways, or around industrial sites. The barriers can be constructed using materials like concrete, wood, or specialized sound-absorbing panels. Additionally, noise absorption can be enhanced by using porous materials or installing acoustic panels in indoor spaces to reduce echo and reverberation.
Noise Control in Transportation: Implementing noise control measures in the transportation sector is crucial. This includes using quieter engine technologies and electric vehicles, which produce significantly less noise compared to traditional internal combustion engines. For aircraft, implementing flight path adjustments, restricting night flights, and utilizing noise-reducing technologies can mitigate noise pollution near airports. In the rail sector, regular maintenance of train tracks and wheels can reduce squealing noises, and the use of noise barriers alongside railway lines can minimize the impact on nearby residents.
Land-Use Planning and Zoning: Strategic land-use planning can help mitigate noise pollution. This involves creating buffer zones between noise-generating activities and noise-sensitive areas, such as residential neighborhoods, schools, and hospitals. Zoning laws can be enacted to restrict certain types of noisy activities in specific areas or impose noise limits on industrial and commercial operations. Proper land-use planning can also involve designing buildings and outdoor spaces with noise-reflecting or noise-absorbing materials to minimize sound propagation.
Public Awareness and Education: Educating the public about the impacts of noise pollution and how to prevent it is essential. Raising awareness can lead to behavioral changes, such as encouraging people to reduce their noise output, use quieter equipment, and adopt noise-reduction practices in their daily lives. Public awareness campaigns can also promote the use of personal hearing protection devices, especially in noisy recreational activities or workplaces. Educating communities about the health risks associated with prolonged exposure to noise pollution can foster a sense of collective responsibility and encourage noise mitigation efforts.
Strict Enforcement and Regulation: Enforcing noise pollution regulations and setting clear standards for acceptable noise levels are necessary to mitigate noise pollution effectively. Governments and local authorities should establish noise limits for various activities and enforce penalties for non-compliance. This includes monitoring noise levels from construction sites, factories, entertainment venues, and transportation hubs. Regular inspections and strict enforcement of these regulations will deter noise polluters and encourage the adoption of noise-reduction technologies and practices.
Noise pollution is a complex issue, and a combination of these solutions is often required to effectively manage and minimize its impact on individuals and communities. It is important to recognize that each situation is unique, and tailored approaches may be necessary to address specific noise pollution challenges. By implementing these strategies and fostering a collective understanding of the negative impacts of noise pollution, we can create quieter and healthier environments for everyone.
