Green Muffler Noise Pollution

When pollutants are introduced into the natural environment and cause harm, this is referred to as pollution. Pollutants are either foreign substances/energies or naturally occurring contaminants that contribute to pollution. Pollution can be caused by chemical substances or energy, such as noise, heat, or light. Pollution is frequently classified as either a point source or a nonpoint source.

Types of Pollution

• Air Pollution: Chemicals and particles are released into the atmosphere. Carbon monoxide, sulfur dioxide, chlorofluorocarbons (CFCs), and nitrogen oxides are common gaseous pollutants created by industry and motor vehicles. When nitrogen oxides and hydrocarbons combine with sunlight, photochemical ozone and smog are produced. Particulate matter, often known as tiny dust, is measured in micrometers and is classified as PM10 to PM2.5.

• Electromagnetic Pollution: the oversupply of non-ionizing electromagnetic radiation, such as radio waves, to which humans are constantly exposed, particularly in major cities. However, it is still unknown whether such types of radiation have any impact on human health.

• Noise Pollution: Road noise, aircraft noise, industrial noise, and high-intensity sonar are all included in this category.

• Soil Pollution: Chemicals are released into the soil as a result of a spill or an underground leak. Hydrocarbons, heavy metals, MTBE, herbicides, pesticides, and chlorinated hydrocarbons are among the most significant soil pollutants.

• Water Pollution: Release of waste and contaminants into surface runoff flowing to surface waters (including urban runoff and agricultural runoff, which may contain chemical fertilizers and pesticides); discharges of untreated sewage and chemical contaminants, such as chlorine, from treated sewage; release of waste and contaminants into surface runoff flowing to surface waters groundwater contamination from waste disposal and seeping into the ground, especially from pit latrines and septic tanks; eutrophication and littering (including human excrement from open defecation, which is still a big concern in many poor countries); eutrophication and littering.

What is a Green Muffler?

Green mufflers are noise pollution management measures that involve planting green plants near noisy areas such as roadsides and industrial areas to block noise from reaching citizens. Typically, 4–5 rows of plants are planted near noisy areas such as roadsides and industrial areas. As a result, dense trees lessen noise pollution by filtering the noise and preventing it from reaching the citizens.

The green muffler is related to the technique that helps to reduce noise pollution. Green muffler scheme refers to a noise absorber which helps to reduce the effect of noise pollution. It reduces air pollution by absorbing polluting gases and causing suspended particulate matter or dust generated by moving vehicles to settle.

Green Muffler Noise Pollution: Green muffler scheme is used to reduce the effect of noise pollution which affects the life of human beings as well as wildlife.

Noise Pollution: Noise pollution, also known as environmental noise or sound pollution, is the spread of noise that has a variety of effects on human or animal behaviour, the majority of which are damaging to some degree. Machines, transportation, and dispersion systems are the primary sources of outdoor noise around the world. 

Noise disintegration or pollution can be caused by poor urban planning, and noise pollution in residential areas can be caused by industrial and residential buildings being built next to each other. Loud music, transportation (traffic, rail, aeroplanes, etc. ), lawn care maintenance, building, electrical generators, explosions, and people are all common sources of noise in residential neighbourhoods.

Types of Noise Pollution

• Man-Made: Noise produced by man-made activity is referred to as this. Construction noise, aircraft noise, automobile traffic noise, household noise, and pub and bar noise are just a few examples. Humans are severely harmed by this type of noise, which can range from 30 to 140 decibels.

• Environmental: Noise created by a range of environmental activities is referred to as "environmental noise." This might range from animal mating cries to thunderstorms with a decibel level of 140.

Various Causes of Noise Pollution

• Industrialization: The majority of sectors rely on enormous machines that can generate a lot of noise. 

• Urban Planning: Poor urban planning is also a major issue in most developing countries. Crowded households, huge families sharing small places, parking wars, and regular fights over basic services all contribute to noise pollution, which can harm society's environment. When residential and industrial buildings are close together in an urban area, noise pollution can occur.

• Transportation: A huge number of automobiles on the road, airplanes flying over houses, and subway trains all make a lot of noise, which many find difficult to adjust to. A result of the excessive noise, a normal person's capacity to hear is impaired.

Effects of Noise Pollution

• Hearing Issues: Any undesirable sound that our ears are not designed to filter can cause health issues. While the human hearing range extends from 20 to 20,000Hz, our hearing is most acute in the 2000 to 5000 Hz frequency range. When it comes to volume, humans can normally hear at a decibel level of 0 dB.

• Psychological Issues: Excessive noise pollution in places like businesses, construction sites, pubs, and even our homes can have a negative impact on our mental health. The amount of irritation rises as the volume of noise rises, and people become less and less patient. These, in turn, can lead to more serious and long-term health problems later in life.

• Cardiovascular Issues: The prevalence of high blood pressure, cardiovascular disease, and stress-related cardiac disorders are on the rise. According to studies, high-intensity noise causes high blood pressure and increases heart rate by disturbing regular blood flow. We must be aware of the negative implications and approach these conditions with caution because lowering these rates to a reasonable level relies on our awareness of noise pollution.

• Effect on Wildlife: Because wildlife is more reliant on sound than humans, they experience significantly greater challenges as a result of noise pollution. Because their life depends on it, animals have a greater sense of hearing than humans. They are more easily disoriented and have a variety of behavioral issues. Hearing loss is common in nature, making animals easy prey and resulting in diminishing numbers. 

Solutions to lower Noise Pollution

• Creating rules that contain both preventative and corrective procedures.

• To ensure noise control and prevent noise pollution, governments can adopt steps such as protecting some areas, parts of the countryside, natural places of interest, city parks, and so on.

• The necessary separation of residential zones from noise sources such as airports.

• Creating pedestrian zones where vehicles are not permitted to enter except to dump items at specific times.

• Excessive noise limitations result in fines.

• Controlling the sound levels in clubs, pubs, parties, and discos is another technique to combat noise pollution.

• Another method for reducing pollution is to remove public loudspeakers.

• Better urban planning can also aid in the creation of ‘No-Noise' zones, where honking and industrial noise is not tolerated.

• Traffic noise can be reduced by up to 3 decibels by replacing ordinary asphalt with more efficient alternatives.
