<<–2/”>a >a href=”https://exam.pscnotes.com/sound/”>Sound is measured in decibels (dB). An increase of about 10 dB is approximately double the increase in loudness.
A person’s hearing can be damaged if exposed to noise levels over 75 dB over a prolonged period of time.
The World Health Organization recommends that the sound level indoors should be less than 30 dB.
Ambient Noise Level Monitoring – Noise Pollution (Control and Regulation) Rules, 2000 define ambient noise levels for various areas as follows-
- Industrial Area—75DB to 70Db (Day time-6am to 10pm and night time 10pm to 6am ..75 is day time and 70 is night time)
- Commercial Area–65 to 55
- Residential Area–55 to 45
- Silence Zone– 50 to 40
- The Government of India on Mar 2011 launched a Real time Ambient Noise Monitoring Network.
- Under this network, in phase- I, five Remote Noise Monitoring Terminals each have been installed in different noise zones in seven metros (Delhi, Hyderabad, Kolkata, Mumbai, Bangalore, Chennai and Lucknow).
In Phase II another 35 monitoring stations will be installed in the same seven cities.
Phase III will cover installing 90 stations in 18 other cities.
Phase-III cities are Kanpur, Pune, Surat, Ahmedabad, Nagpur, Jaipur, Indore,
Bhopal, Ludhiana, Guwahati, Dehradun, Thiruvananthpuram, Bhubaneswar,
Patna, Gandhinagar, Ranchi, Amritsar and Raipur.
Silence Zone is an area comprising not less than 100 metres around hospitals, educational institutions, courts, religious places or any other t area declared as such by a competent authority.,
Sound pollution is unwanted or excessive sound that can have harmful effects on human health and the Environment. Sources of sound pollution include transportation, Industry, construction, and recreational activities. Effects of sound pollution can include hearing loss, Stress, sleep disturbance, and cardiovascular problems. There are a number of ways to reduce sound pollution, including using quieter equipment, installing sound barriers, and creating noise-free zones. Laws and regulations on sound pollution vary from country to country, but most countries have some form of legislation in place to protect people from the harmful effects of noise. International initiatives on sound pollution include the World Health Organization’s (WHO) Guidelines for Community Noise and the United Nations Environment Programme’s (UNEP) Global Strategy for Action on Noise. Research on sound pollution is ongoing, and there is a growing body of evidence that suggests that noise pollution can have a significant impact on human health and the environment. The future of sound pollution is uncertain, but it is likely that the problem will only get worse as the world becomes more industrialized and urbanized.
What is sound pollution?
Sound pollution is unwanted or excessive sound that can have harmful effects on human health and the environment. Sound pollution can be caused by a variety of sources, including transportation, industry, construction, and recreational activities.
Sources of sound pollution
Transportation is a major source of sound pollution. Traffic noise can be particularly harmful to people who live near busy roads. Industry is another major source of sound pollution. Factories and other industrial facilities can generate a lot of noise, which can disturb people who live nearby. Construction is also a source of sound pollution. The noise from construction equipment can be very loud and can disturb people who live nearby. Recreational activities, such as sporting events and concerts, can also be sources of sound pollution. The noise from these activities can be very loud and can disturb people who live nearby.
Effects of sound pollution
Sound pollution can have a number of harmful effects on human health. Exposure to loud noise can cause hearing loss, stress, sleep disturbance, and cardiovascular problems. Sound pollution can also have a negative impact on the environment. It can disturb wildlife, damage Ecosystems, and interfere with Communication.
How to reduce sound pollution
There are a number of ways to reduce sound pollution. One way is to use quieter equipment. For example, using electric lawnmowers instead of gas-powered lawnmowers can reduce noise pollution. Another way to reduce sound pollution is to install sound barriers. Sound barriers can be used to block noise from highways, factories, and other noisy sources. Creating noise-free zones is another way to reduce sound pollution. Noise-free zones can be created in parks, libraries, and other public spaces.
Laws and regulations on sound pollution
Laws and regulations on sound pollution vary from country to country. However, most countries have some form of legislation in place to protect people from the harmful effects of noise. In the United States, the Environmental Protection Agency (EPA) regulates noise pollution. The EPA sets standards for noise levels in different environments, such as homes, schools, and workplaces. The EPA also enforces these standards.
International initiatives on sound pollution
There are a number of international initiatives on sound pollution. The World Health Organization (WHO) has developed Guidelines for Community Noise. These guidelines recommend maximum noise levels for different environments, such as homes, schools, and workplaces. The United Nations Environment Programme (UNEP) has developed a Global Strategy for Action on Noise. This strategy aims to reduce the impact of noise pollution on human health and the environment.
Research on sound pollution
Research on sound pollution is ongoing. There is a growing body of evidence that suggests that noise pollution can have a significant impact on human health and the environment. Some of the research on sound pollution has focused on the effects of noise pollution on hearing loss. Other research has focused on the effects of noise pollution on stress, sleep disturbance, and cardiovascular problems. Research has also focused on the effects of noise pollution on wildlife, ecosystems, and communication.
Future of sound pollution
The future of sound pollution is uncertain. However, it is likely that the problem will only get worse as the world becomes more industrialized and urbanized. As more people live in cities, they will be exposed to more noise pollution. This could lead to an increase in the number of people who suffer from the harmful effects of noise pollution.

What can be done to reduce sound pollution?
There are a number of things that can be done to reduce sound pollution, including:
- Enforcing noise regulations. Governments can enact and enforce laws that limit noise levels in public areas.
- Using quieter equipment. Manufacturers can design and produce equipment that produces less noise.
- Planning development carefully. Planners can take steps to reduce noise levels in new developments, such as by locating noisy activities away from residential areas.
