Essay on Noise Pollution

Noise pollution is the excessive and unnecessary sound created by artificial activities. In the past, air-traffic control towers and factories were the only sources of noise pollution. Nowadays, noise pollution has become a severe problem in many parts of the world.

Definition of Noise Pollution

Noise pollution is the presence of unwanted sound in a place, significantly when it interferes with normal activities or disturbs the peace. Many things, such as construction work, traffic, and aircraft, can cause noise pollution.

Types of Noise Pollution

• Continuous noise

• Intermittent noise

• Impulsive noise

• Low-frequency noise

1. Continuous noise

The continuous noise is any sound that exceeds what you can hear with the naked ear. However, continuous noise can cause stress and sleep disturbance in people exposed to it over an extended period. For example, someone working on an assembly line at a factory would be exposed to thunderous noises (i.e., 92 dB) every shift. The human body is not designed to withstand such high decibels continuously for long periods without getting affected; this is one reason we need some way of protecting ourselves from continuous noise exposure.

Since there are many ways in which humans can be exposed to excessive levels of continuous sound—from factories and construction sites, through transportation systems (elevators), etc.—the best way for us all across our communities is through creating awareness about how much damage sound pollution does on our health through hearing loss among other things like cardiovascular disease risk factors."

2. Intermittent noise

Noise pollution can cause stress, sleep problems, and hearing loss. A study published in the American Journal of Epidemiology found that noise pollution increased people'speople's exposure to traffic noise by 60 percent.

It also reduces the quality of your sleep by disrupting circadian rhythms—the internal biological clock that regulates our body'sbody's 24-hour rhythm. Exposure to loud noises triggers a release of cortisol (a hormone released by the adrenal gland), which raises blood pressure and heart rate. This increases the risk for cardiovascular disease, hypertension (high blood pressure), diabetes, obesity, and stroke.

3. Impulsive noise

Impulsive noise is any sound that passes through the eardrum and causes damage to the inner ear. The most common example of impulsive noise is, of course, loud music. You might hear it as "thumping" or "booming," but other sounds can also be impulsive:

• Driving under normal conditions (i.e., without car horns) can cause permanent hearing loss by damaging your auditory nerves.

• Aircraft engines produce very high levels of EMI (electromagnetic interference). This type of EMI exposure has been linked to tinnitus in some studies. However, more research needs to be done before a definitive conclusion can be made about whether this condition is caused by electromagnetic radiation or something else (such as exposure to loud noises).

4. Low-frequency noise

Low-frequency noise is environmental noise that the human ear can hear. This kind of noise occurs at low frequencies between 20 Hz and 20 kHz (Hertz). Low-frequency sounds are often referred to as "white noise" because they have an equal loudness across all frequencies, making it difficult to identify individual frequencies.

Low-frequency sounds are caused by trains and aircraft; however, they can also come from other sources like construction projects or machinery working in your home or workplace. The main issue with low-frequency noise is that it leads to hearing loss and stress over time if exposure continues long enough for damage to occur within your inner ear structures, such as the Cochlea (inner ear).

Causes of Noise Pollution

Noise pollution is caused by the excessive or unwanted sound produced by humans and natural sources. There are several ways in which noise can be harmful to people:

• It can damage hearing and other senses.

• It may cause stress, anxiety, and depression.

• It may lead to sleep disorders such as insomnia, restlessness at night, and daytime fatigue due to lack of sleep.

Protect yourself and others from sound pollution

• Use earplugs.

• Use earphones.

• Use a white noise machine, fan, air purifier, or humidifier to drown out the noise you are trying to block (like traffic).

• Wear earmuffs if you are particularly sensitive to loud noises—they will protect against mastication-damaging frequencies up to 140 dB (decibels).


Noise pollution is a severe issue. The noise pollution caused by cars and trucks in cities can hurt people's health, cause stress and anxiety, and even lead to hearing problems. To combat this problem, we need to ensure that new development projects include noise mitigation measures so that people do not have to live with constant loud sounds all day.


What is noise pollution explain?

Noise pollution is any unwanted sound that has a harmful effect on humans, livestock and wildlife. The intensity of the noise in decibels can be used to indicate how loud it is.

How do you stop noise naturally?

Insulate Interior Walls

Is it OK to wear earplugs every night?

Over time, if earplugs are used every night, they can push your body's natural earwax far up into your inner ears. This may cause temporary hearing loss but won't have any lasting effects (assuming you don't use them for too long).
