Noise pollution occurs when unwanted sound disrupts normal activities. It is caused mainly by transportation systems, construction activities, and industrial operations in urban areas. The World Health Organization recognizes noise pollution as a major threat to human well-being due to its links to health issues like high blood pressure, hearing loss, and sleep disruption. Some solutions to noise pollution include planting trees near sound sources, maintaining vehicles and machinery, using soundproofing in buildings, and educating the public.
Any unwanted, disturbing or harmful sound that impairs or interferes with hearing, causes stress, hampers concentration and work efficiency or causes accidents called noise pollution.
This presentation is useful to all the students who studied and get information about noise pollution. It gives a basic knowledge about noise pollution and also useful for them who study in environmental engineering or civil engineering or science.

hat is Noise Mapping ?
A Noise Map is a map of an area which is coloured according to the noise levels in the area. Sometimes, the noise levels may be shown by contour lines which show the boundaries between different noise levels in an area.
The noise levels over an area will be varying all the time. For example, noise levels may rise as a vehicle approaches, and reduce again after it has passed. This would cause a short-term variations in noise level. In the slightly longer term, noise levels may be higher in peak periods when the roads are busy, and lower in off-peak periods. Then again, there is a greater volume of activity from more people and traffic in the day-time than in the evening or at night. In the longer term, wind, weather and season all affect noise levels.
This means that it is not possible to say with confidence what the noise level will be at any particular point at any instant in time, but where the noise sources are well-defined, such as road or rail traffic, or aircraft, then it is possible to say with some confidence what the long-term average noise level will be.
It may be thought that the best way of doing this is by measurement, but experience shows that this is not the case. For a start, a long-term average must be measured over a long period of time. Secondly, to obtain complete coverage of an area, measurements would have to be made on private property, where access might be difficult, and thirdly, measurements cannot distinguish the different sources of noise, so they would not be able to give information on how much noise was being made by each of the sources in an area.
For these and other reasons, noise mapping is usually done by calculation based on a computerised noise model of an area, although measurements may be appropriate in some cases.
A further benefit of having a noise model is that it can be used to assess the effects of transportation and other plans. Thus the effect of a proposed new road can be assessed and suitable noise mitigation can be designed to minimise its impact. This is particularly important in noise action planning, where a cost-benefit analysis of various options can be tested before a decision is made.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

2. WHAT IS NOISE POLLUTION?
Sound that is unwanted or disrupts one’s quality of life is
called as noise. When there is lot of noise in the
environment, it is termed as noise pollution.
Sound becomes undesirable when it disturbs the normal
activities such as working, sleeping, and during
conversations.
It is an underrated environmental problem because of the
fact that we can’t see, smell, or taste it.
World Health Organization stated that “Noise must be
recognized as a major threat to human well-being”
3. HEALTH EFFECTS
According to the USEPA, there are direct links between noise
and health. Also, noise pollution adversely affects the lives of
millions of people.
Noise pollution can damage physiological and psychological
health.
High blood pressure, stress related illness, sleep disruption,
hearing loss, and productivity loss are the problems related to
noise pollution.
It can also cause memory loss, severe depression, and panic
attacks.
4. SOURCES OF NOISE POLLUTION
Transportation systems are the main source of noise pollution
in urban areas.
Construction of buildings, highways, and streets cause a lot of
noise, due to the usage of air compressors, bulldozers,
loaders, dump trucks, and pavement breakers.
Industrial noise also adds to the already unfavorable state of
noise pollution.
Loud speakers, plumbing, boilers, generators, air
conditioners, fans, and vacuum cleaners add to the existing
noise pollution.
5. SOLUTIONS FOR NOISE
POLLUTION
Planting bushes and trees in and around sound generating
sources is an effective solution for noise pollution.
Regular servicing and tuning of automobiles can effectively
reduce the noise pollution.
Buildings can be designed with suitable noise absorbing
material for the walls, windows, and ceilings.
Workers should be provided with equipments such as ear
plugs and earmuffs for hearing protection.
6. SOLUTIONS FOR NOISE
POLLUTION
Similar to automobiles, lubrication of the machinery and
servicing should be done to minimize noise generation.
Soundproof doors and windows can be installed to block
unwanted noise from outside.
Regulations should be imposed to restrict the usage of
play loudspeakers in crowded areas and public places.
Factories and industries should be located far from the
residential areas.
7. SOLUTIONS FOR NOISE
POLLUTION
Community development or urban management should
be done with long-term planning, along with an aim to
reduce noise pollution.
Social awareness programs should be taken up to
educate the public about the causes and effects of noise
pollution.
