Noise Pollution

Noise is an unpleasant and unwelcome sound that causes human discomfort.

The volume of a sound is measured in decibels (dB). The human ear can detect the faintest sound at 1 Db. As civilizations’ populations have grown, noise pollution has become a concern. Among the major causes are vehicles, aircraft, industrial machines, loudspeakers, crackers, and other similar devices. Other appliances, such as televisions, transistors, radios, and so on, contribute to noise pollution when used at high volumes.

Types of Noise Pollution

Transport Noise: It primarily consists of traffic noise, which has increased in recent years as the number of vehicles has increased. Noise pollution causes deafness in the elderly, headaches, hypertension, and other health problems.

1. Neighbourhood Noise: The sound of gadgets, household utensils, and so on. Musical instruments, transistors, loudspeakers, and other electronic devices are some of the most common sources.
2. Industrial Noise: It is the high-intensity sound produced by heavy industrial machines. Many studies have found that industrial noise pollution reduces hearing ability by around 20%.

Causes and Sources of Noise Pollution

1. Industrialisation: Industrialisation has resulted in an increase in noise pollution due to the use of heavy machinery such as generators, mills, and massive exhaust fans, which produce unwanted noise.
2. Vehicles: The second cause of noise pollution is an increase in the number of vehicles on the road.
3. Events: Loudspeakers are used to play music at weddings and public gatherings, causing unwanted noise in the neighbourhood.
4. Construction sites: Noise pollution is exacerbated by mining and building construction.

The environment is defined as a physical system’s surroundings, which may interact with other systems by exchanging mass and energy. All living and nonliving things are included in the natural environment. Because the environment is the setting in which we live, it is our responsibility to keep it safe from harm. Environmental pollution is one of the most serious issues confronting human society today. The three basic areas of environmental pollution are air, water, and soil.
