Reducing Noise Pollution: Practical Steps And Wikipedia's Role

Noise pollution is a serious issue that can have a detrimental impact on people's health and the environment. There are several ways to reduce noise pollution, including turning off appliances when not in use, planting trees, using earplugs, and regular maintenance of vehicles and machines. Electric and hybrid vehicles can also help reduce noise pollution, as can improved tyre tread designs for trucks and better shielding of diesel stacks. Noise barriers have shown mixed results in their ability to reduce noise pollution effectively.

Transportation noise control

To reduce transportation noise pollution, people can be encouraged to use alternative means of transport such as bicycles or electric vehicles. Electric and hybrid vehicles could reduce noise pollution, but only if they make up a high proportion of total vehicles on the road. Even if traffic in an urban area reached a makeup of fifty percent electric vehicles, the overall noise reduction achieved would only be a few decibels and would be barely noticeable. Highway noise is less affected by motor type, since the effects at higher speed are aerodynamic and tire noise related.

Other ways to reduce transportation noise pollution include improved tyre tread designs for trucks, better shielding of diesel stacks, and local vehicle regulation of unmuffled vehicles.

Architectural design

The architectural design of buildings can play a crucial role in reducing noise pollution. Here are some strategies that can be implemented:

Firstly, the layout and orientation of buildings can be carefully planned to minimise noise intrusion. For example, positioning buildings in such a way that they act as noise barriers for each other, or incorporating noise-reflecting surfaces to direct sound away from occupied areas. In urban areas, where space is limited, the use of noise-reflecting barriers or acoustic fencing can be considered to reduce the impact of noise on nearby residents.

Secondly, the use of sound-absorbing materials in construction can help to reduce noise transmission. This includes the use of insulation, double or triple-glazed windows, and sound-absorbing panels. These materials can be particularly effective in reducing indoor noise levels, creating quieter indoor environments for occupants.

Thirdly, architectural design can also involve the creation of buffer zones or green spaces between noise sources and sensitive areas. These zones can act as natural sound barriers, absorbing and dispersing sound waves before they reach residential areas. Planting trees and other vegetation can be an effective way to create these buffer zones, as well as providing additional environmental benefits.

In addition to these strategies, proper maintenance of building systems and equipment is essential to minimise noise pollution. Regular checks and lubrication of movable parts can help to reduce friction and, consequently, noise levels. Furthermore, the use of noise-reducing technologies, such as silencers or mufflers, can be incorporated into the design to mitigate noise at the source.

Lastly, when designing buildings in noise-sensitive areas, it is important to consider the impact of indoor activities on the surrounding environment. This includes the selection of appropriate noise-reducing materials for flooring and the implementation of noise control measures for specific activities, such as amplified music or industrial processes. By carefully considering these factors, architects can play a vital role in creating quieter, more pleasant environments for occupants and neighbouring communities.

Urban planning

• Zoning codes that separate residential areas from sources of noise pollution, such as airports.
• Protecting certain areas, such as the countryside, areas of natural interest, and city parks, from noise pollution.
• Establishing regulations that include preventive and corrective measures, such as mandatory separation between residential zones and sources of noise and fines for exceeding noise limits.
• Using noise barriers, although studies on their effectiveness have shown mixed results.
• Encouraging the use of electric and hybrid vehicles, which produce less noise pollution than traditional cars, especially at higher speeds.
• Improving the design of roads and highways to reduce noise, such as through better shielding of diesel stacks and improved tyre tread designs for trucks.

Occupational noise control

Noise control or noise mitigation is a set of strategies to reduce noise pollution or to reduce the impact of that noise, whether outdoors or indoors. Occupational noise control is one of the main areas of noise mitigation or abatement.

Another strategy is to use noise-absorbing materials to insulate buildings and create barriers that block or absorb sound waves, reducing the amount of noise that escapes or enters a building. However, the effectiveness of noise barriers has been questioned, with studies showing mixed results.

In addition to physical measures, spreading awareness about noise pollution and its effects on human health and the environment is crucial. Educating people about noise pollution can lead to behavioural changes that reduce noise levels. This includes encouraging people to turn off appliances when not in use, plant trees, and use alternative means of transport such as bicycles or electric vehicles.

Electric and hybrid vehicles

Roadway noise and aircraft noise are the most pervasive sources of environmental noise. The main areas of noise mitigation or abatement are transportation noise control, architectural design, urban planning through zoning codes, and occupational noise control.

International bodies like the WHO agree that awareness of noise pollution is essential. They recommend opting for alternative means of transport such as bicycles or electric vehicles over taking the car. Governments can also take measures to ensure correct noise management and reduce noise pollution. For example, protecting certain areas – parts of the countryside, areas of natural interest, city parks, etc. – from noise, establishing regulations that include preventive and corrective measures – mandatory separation between residential zones and sources of noise like airports, fines for exceeding noise limits, etc.
