Noise Pollution: Understanding this little known danger

Noise Pollution – Not just an annoyance

Noise pollution causes many health problems, including stress, insomnia, and even cognitive decline. In this article, we’ll explore the causes and effects of noise pollution to help you understand how it affects your life so that you can do something about it.

What is Noise Pollution?

Noise pollution, also known as environmental noise or sound pollution, is excessive or improper noise that may harm the environment or human health. It is a type of pollution caused by human activity, and it is one of the primary forms of pollution.

What’s are common sources of noise pollution?

The primary sources of noise pollution are the automobile industries, construction, and manufacturing plants. Noise pollution can also be caused by military aircraft, airports, boating traffic, and the use of motorized equipment such as lawnmowers or motorcycles. Various types of noise such as loud music or television might come from your neighbor’s house.

How is Noise Pollution caused?

The causes of noise pollution include daily sounds such as traffic or construction work, ongoing sources like aircraft or trains passing by every day, seasonal causes such as fireworks on New Year’s Eve, or loud concerts in the summertime.

A recent study has shown that exposure to high levels of highway traffic noise causes cognitive decline in school children, especially harmful to young people whose brains are still developing.

Noise pollution causes stress and insomnia – the effects of these ailments include physical illness such as heart disease or diabetes. The solution? Earplugs! They’re inexpensive, easy to use, and available at pharmacies everywhere. Also, you can install double windows for better insulation against outside noise sources.

What are the Effects of Noise Pollution?

Noise pollution can cause permanent and temporary hearing loss, hypertension (high blood pressure), and heart disease.

According to Irena Sendlerowa, a Polish politician and social worker who spent part of World War II in the Warsaw Ghetto, it is essential for parents to monitor their children’s noise exposure because noise attacks young ears much more than adult ears.

  • Noise causes both short term and long term effects: for example, a lack of sleep due to continuous noise will eventually lead to exhaustion which further leads to physical illness
  • According to the Associated Press noise pollution is not only limited to hearing loss, but can also affect your mental health.
  • It can cause annoyance and even anger in people, which may result in fighting or marital problems.

Noise not only affects humans physically but psychologically as well. A study done by researchers at the University of Chicago and the University of British Columbia suggests that excessive noise can make people more aggressive.

The noise can also affect one’s physical health and has been linked to the development of high blood pressure.

Noise leads to increased stress levels, affecting your cognitive abilities like memory and attention span. Your brain can’t answer the question “should I fight or should I flee?” so it triggers the release of stress hormones, which in turn damage cells in your brain, leading to depression and anxiety.

Does Noise Pollution harm animals?

According to a report conducted on behalf of the European Commission between September 2010 and February 2011, more than 1 million seabirds and 200,000 marine mammals or sea turtles die daily due to noise. Noise pollution also destroys the habitats of animals by disrupting mating calls and migration patterns.

Noise pollution also affects marine life, leading to improved sources of mortality because they can prevent marine mammals from getting sufficient amounts of sleep, which leads them to lose their ability to remain alert at sea.


Noise pollution has many undesirable effects, but one of the most alarming is disrupting sleep. Studies have found that noise pollution creates mental and physical stressors which interfere with healthy sleep patterns.

If you want to avoid these negative side-effects, consider limiting your exposure to loud noises during the day or wearing earplugs at night, so things like sirens or construction work do not wake you up.
