What are the best practices and examples of noise control in urban planning from around the world?

2 Noise mapping and monitoring

One of the key tools for noise control in urban planning is noise mapping and monitoring. Noise mapping is the process of creating a visual representation of the noise levels and patterns in a given area, using data from measurements, models, or surveys. Noise monitoring is the process of collecting and analyzing noise data over time, using sensors, meters, or apps. Noise mapping and monitoring can help urban planners identify noise hotspots, assess noise exposure and annoyance, evaluate noise mitigation measures, and inform noise policies and standards.

3 Noise reduction and mitigation

Another essential tool for noise control in urban planning is noise reduction and mitigation. Noise reduction is the process of lowering the noise levels at the source or along the propagation path, using techniques such as traffic management, low-noise vehicles, sound barriers, insulation, and landscaping. Noise mitigation is the process of minimizing the adverse effects of noise on the receivers, using techniques such as noise zoning, land use planning, building design, soundproofing, and masking. Noise reduction and mitigation can help urban planners create quieter and healthier environments for living, working, and recreation.

4 Noise perception and preference

A third important tool for noise control in urban planning is noise perception and preference. Noise perception and preference are the subjective and psychological aspects of how people experience and evaluate noise in their surroundings. They depend on factors such as personal characteristics, expectations, attitudes, emotions, and context. Noise perception and preference can influence how people cope with and react to noise, as well as their satisfaction and well-being. Urban planners need to understand and address the diverse and dynamic needs and preferences of different groups and individuals in relation to noise.

5 Noise awareness and education

A fourth useful tool for noise control in urban planning is noise awareness and education. Noise awareness and education are the processes of informing and engaging the public and stakeholders about the causes, effects, and solutions of noise pollution. They can involve activities such as campaigns, events, publications, websites, apps, and participatory projects. Noise awareness and education can help urban planners raise awareness and understanding of noise issues, promote positive behaviors and attitudes, foster collaboration and participation, and empower citizens and communities to take action.

6 Examples of noise control

There are many examples of noise control in urban planning from around the world that demonstrate the application and effectiveness of the tools mentioned above. For instance, the European Union's Environmental Noise Directive requires member states to produce strategic noise maps and action plans every five years. Additionally, New York City's Quiet Streets program intends to reduce traffic noise through the installation of speed humps, signs, and markings. Furthermore, the UK's Quiet Mark scheme awards a distinctive purple logo to products and services that meet low-noise criteria. Vancouver, Canada has created a Soundscape Park with a water fountain, bamboo grove, and soundwalk to create a pleasant acoustic environment. Lastly, Hush City app allows users to identify, record, rate, and share quiet spots in their cities through a crowdsourced approach.
