What are cities doing to combat noise pollution today?
Cities around the world are taking various measures to combat noise pollution and improve the quality of life for their residents. Some common strategies include:
Noise mapping and monitoring: Many cities create noise maps to identify high noise pollution areas and monitor noise levels over time. These maps help inform decision-makers on where to focus their efforts and assess the effectiveness of noise mitigation strategies.
Traffic management: Cities implement traffic management measures to reduce noise pollution from vehicles. These measures may include imposing speed limits, encouraging the use of electric vehicles, establishing low-emission zones, implementing congestion pricing, and promoting public transportation.
Urban planning and zoning: Cities use zoning regulations to separate residential areas from noisy commercial or industrial zones. They also consider noise pollution when planning new infrastructure projects, such as roads, airports, or railways, and incorporate noise barriers or buffer zones to minimize noise exposure for nearby residents.
Building regulations and design: Cities often enforce building codes that require soundproofing or noise insulation materials in residential and commercial constructions. They may also encourage or require the use of green roofs, vegetative facades, or noise barriers to absorb and reduce noise transmission.
Public awareness campaigns: Cities may run public awareness campaigns to educate residents about the effects of noise pollution and encourage them to adopt quieter behaviors, such as using earplugs, turning down music, or limiting the use of noisy appliances during certain hours.
Noise ordinances and enforcement: Many cities have noise ordinances that set limits on acceptable noise levels during specific times of the day or for particular activities. These regulations are enforced by local authorities, and violations can result in fines or other penalties.
Green spaces and urban forestry: Cities invest in creating and maintaining parks, green spaces, and urban forests, which can help absorb and dissipate noise, providing quieter environments for residents and enhancing overall well-being.
Research and innovation: Cities collaborate with academic institutions and researchers to study the impacts of noise pollution and develop innovative solutions for monitoring, mitigation, and management.
Each city's approach to combating noise pollution may vary depending on its unique challenges, resources, and priorities. However, the common goal is to create healthier, more livable urban environments for their residents.
According to the World Economic Forum, 68% of the global population will live in cities by 2050. This increase in dwellings and movement will generate safety, health, access and mobility challenges for those cities. The flow on effect of this will be noise and the impact of that on the current but also future communities.
By considering noise levels in their planning, cities can better prepare for the growth of their city and prioritize the needs of their growing population in order to create a thriving and sustainable city.
Oslo, Norway
Oslo, the Capital of Norway has a population of 634,000 inhabitants at 454km2
Throughout the world, Oslo is considered to be one of the most Noise aware cities and have instigated a variety of methods to combat it
In order to Monitor noise pollution, Oslo had implemented costly Noise monitoring devices throughout the city and its ports
Efforts to reduce noise pollution include changes in infrastructure, subsidized residential sound proofing and further subsidies for transitions from Diesel to elecrtic vehicles

Paris, France
Paris has a population of 2.1 million inhabitants at 105km2
The densely populated city has realised Noise Pollution as a crucial environmental factor to tackle and have done so through increase monitoring and implemented policies
a limit of 85dB has been set for vehicle sound emissions. Noise radars that catch vehicles crossing this sound level will face fines
Even with sound radars, the majority of the city is excluded and accurate measurements are difficult to come by
Designates zones that prohibt vehicular traffic help create Noise Pollution refuges
Madrid, Spain
Madrid, the capital and largest city in Spain, has more than 3 million inhabitants in a highly urbanized area.
With such high density in a small space, it’s only 604km2, the city has identified that air pollution including noise has become a growing concern. In order to reduce the noise pollution, Madrid City Council has implemented a pioneering city-wide noise monitoring network to help them in their fight against it.
Since 1994, the city has been installing instrumentation to determine the temporal evolution or changes over time of environmental noise levels within the vicinity of each station with data captured in real-time and published on the municipal website daily.
