Sound Pollution's Impact On Happiness: Skylines And Wellbeing

In the game Cities: Skylines, sound pollution is an important factor to consider when planning your city. Sound pollution, or noise pollution, is caused by loud sounds from various sources such as traffic, industry, commercial zones, and unique buildings. This type of pollution can have negative effects on the well-being and happiness of citizens, potentially causing them to move out or even leading to illness and death if not addressed. Therefore, it is crucial to manage noise pollution effectively to ensure the happiness of your citizens and the success of your city. This involves strategic planning, such as proper zoning and the use of sound barriers, to minimize the impact of noise on residential areas.

Traffic noise

• Annoyance and Stress: Traffic noise can cause annoyance and stress, which can lead to unhappiness. According to the World Health Organization (WHO), one-third of EU citizens are annoyed by environmental noise, and it can affect their overall life satisfaction.
• Sleep Disturbance: Traffic noise, especially at night, can disrupt sleep, leading to fatigue and irritability, affecting happiness.
• Health Issues: Prolonged exposure to traffic noise has been linked to various health issues, including cardiovascular disease and diabetes. These health problems can impact overall happiness and well-being.
• Quality of Life: Traffic noise can negatively impact people's quality of life, including their physical and mental health. It can affect their ability to relax and enjoy their surroundings, ultimately influencing their happiness.
• Mental Health: Studies have found associations between traffic noise and mental health issues such as depression and anxiety. This can, in turn, affect a person's overall happiness.

Commercial zones

In the city-building game Cities: Skylines, sound pollution is a feature that affects the happiness of citizens. While it does not make them sick, exposure to noise pollution causes stress and reduces their well-being. This is reflected in the game by a decrease in land value.

The level of noise pollution caused by commercial zones depends on their density. High-density commercial zones will cause citizens living directly across the street to get sick sometimes. It is recommended to keep high-density commercial zones at least one full street away from residential areas to avoid this issue. Low-density commercial zones, on the other hand, do not cause as much noise pollution and can be placed in residential areas without causing significant problems.

To mitigate the negative effects of noise pollution, players can use offices or parks as a buffer between commercial and residential zones. Trees can also be used to reduce noise slightly and improve the happiness of citizens. Additionally, players should pay attention to the indicators shown when placing buildings that produce noise, such as the red ring and the headphones icon, to ensure that they are placed away from residential areas.

Industrial zones

Noise pollution is a major concern in industrial settings, with nearly 30 million people in the United States exposed to hazardous noise levels at their workplaces. This not only affects workers' physical and mental health but also significantly impacts the environment and surrounding communities.

Generic industrial zones in Cities: Skylines, by default, have high levels of noise pollution. However, as these zones level up, they will produce lower amounts of noise pollution. Increasing the level of industry buildings also reduces the amount of ground pollution produced.

Industrial noise is often loud and continuous and can have a high frequency, making it more damaging to human health and the environment. It can come from various sources, such as machinery, equipment, processes, and operations. The noise level in industrial settings can often exceed the permissible exposure limit, with some workers being exposed to levels as high as 120 dB.

Low-frequency noise can result in physical symptoms such as nausea, headaches, and dizziness, while high-frequency noise can cause hearing loss. Prolonged exposure to industrial noise can lead to severe health consequences, including hearing loss, tinnitus, and stress-related disorders.

To combat industrial noise pollution, engineering controls can be implemented to reduce noise levels by modifying equipment or processes. Common measures include installing silencers on machinery, adding insulation to walls and ceilings, enclosing noisy equipment in soundproof rooms, and properly maintaining and lubricating equipment. Administrative controls, such as limiting workers' exposure to loud noise and providing personal protective equipment (PPE), are also crucial.

In the game, it is important to keep industrial zones separate from residential areas, as residential zones are the most negatively affected by noise pollution. Placing offices between industrial and residential zones can help buffer the noise. Additionally, upgrading roads near industrial zones with sound barriers and trees can help reduce noise pollution.

Residential zones

In the game Cities: Skylines, sound pollution, or noise pollution, is an important factor to consider when designing residential zones. Noise pollution is caused by loud sounds from various sources, including wind turbines, traffic, industrial zones, and commercial zones. While it doesn't make citizens as sick as ground or water pollution, it causes stress and reduces overall happiness.

To create happy residential zones, it's important to keep noisy areas away from residential areas. Here are some strategies to achieve this:

• Highway and road planning: Utilise sound barriers along highways and busy roads to block traffic noise. Additionally, consider building roads underground, as this significantly reduces noise pollution. Avoid placing residential zones directly on busy streets, especially six-lane streets.
• Zoning and buffering: Properly zone your districts to separate residential zones from noisy areas. Use commercial zones, such as offices, as buffers between residential and high-noise areas. Offices produce no noise pollution and can act as effective noise barriers.
• Greenery: Incorporate tree-lined roads and large parks near residential zones to help reduce noise pollution. Trees need to be used in large numbers to have a significant impact.
• Traffic management: Implement policies to reduce traffic volume and encourage quieter vehicles. For example, promote electric cars and restrict large vehicles. Speed bumps can also reduce traffic speed and noise, while pedestrian streets create peaceful neighbourhoods.
• Public transportation: Provide efficient public transportation options, such as buses, trams, metros, and trains. This not only increases happiness by providing more services but also reduces traffic volume and, consequently, noise pollution.
• Sound pollution monitoring: Utilise the noise pollution info view in the game to identify loud areas. This will help you make informed decisions about where to place residential zones and implement noise reduction strategies.

Health impacts

Sound pollution, or noise pollution, is a growing concern across Europe. The European Environmental Agency reports that noise ranks second only to air pollution as the environmental exposure most harmful to public health. According to the International Commission on Biological Effects of Noise, the threats posed by noise are "often underestimated" in sectors from government regulation to healthcare practice.

Noise pollution has been deemed a "growing danger to the health and welfare of the Nation's population" by US agencies such as the EPA. Researchers and clinicians have found that noise pollution can have various adverse effects on human health, including:

• Driving hearing loss, tinnitus, and hypersensitivity to sound
• Causing or exacerbating cardiovascular disease
• Causing or exacerbating type 2 diabetes
• Sleep disturbances
• Stress
• Mental health issues, including cognitive impairment and memory impairment
• Attention deficits
• Childhood learning delays
• Low birth weight

Additionally, noise pollution has been linked to climate change. Many contributors to global warming, such as transportation and fossil fuel extraction, also generate noise. Urban sprawl and deforestation remove natural sound buffers while technologies used to mitigate climate change, like air conditioners and generators, can be noisy.

In the game Cities: Skylines, noise pollution is caused by traffic, commercial and industrial areas, certain city services, and even leisure buildings. Citizens exposed to high levels of noise pollution will become ill, and their happiness and overall well-being will decrease. If the noise pollution issues are not addressed, citizens will eventually die, causing strain on medical facilities.

To reduce noise pollution in Cities: Skylines, it is important to keep heavily trafficked areas away from residential zones. Trees can act as sound barriers and reduce noise, especially when placed alongside roads and highways. Implementing sound barriers on highways and using speed bumps can also help lower noise levels.
