Living in large cities sometimes has its own challenges. Stagnant road conditions plus vehicle horns that roared caused fatigue on their own. If the noise starts to interfere, it could be a sign of noise pollution!
Yep, pollution is not only related to water, air and soil pollution. In fact, sound can also be pollution! Learn more about the following trivia!
1. Actually, what is noise pollution?
Let’s get closer with noise pollution. Sound pollution is the spread of noise due to human activities that can have harmful effects on humans and animals. This source of noise is caused by machinery, transportation to recreational entertainment (music concerts for example).
Bad city planning can cause noise pollution. For example, building a residential complex close to a sports stadium or industrial area. Sound pollution is allegedly able to disrupt the quality of human life.
2. How loud is the sound to be categorized as pollution?
The level of loudness is represented by decibels (dB). Normal conversations produce 60 dB of sound, lawn mowers have a volume of 90 dB and music concerts are generally above 120 dB. Meanwhile, the sound of the car racing atmosphere produced 130 dB and the sound of gunfire released 140 dB sound.
According to the Health Link BC page, sounds above 85 dB can be categorized as dangerous, depending on how long and how often we are exposed to the sound. Therefore, we are advised to use ear protectors or sound absorbers.
3. What are the dangers of noise pollution to humans?
The World Health Organization (WHO) estimates that there are around 1 million lives per year in Western European countries due to noise pollution. Sound pollution has negative implications for health, such as triggering cardiovascular problems, high blood pressure, heart attack, stroke and coronary heart disease.
In addition, noise pollution is also associated with mental health problems. Such as the emergence of anxiety, depression, sleep problems and stress, said the Brain Facts page. Wow, can that effect be true?
4. How can noise pollution harm animals?
Not only is it harmful to humans, noise pollution also has a negative effect on animals. For example what happens to whales and dolphins that are disturbed by ship noise. It should be of particular concern because the North Atlantic right whale (Eubalaena glacialis) is threatened with extinction due to the high sea traffic.
Land animals are also disturbed by noise pollution. The number of bird species has declined due to chronic noise in large urban areas. Animals also adapt, as in urban great bird that increases the frequency of tweets and European robins adjust their singing time when the city is in a calmer condition, said the IFL Science page.
5. Industries and factories are the main triggers for noise pollution
If you are wondering what are the main causes of noise pollution, the answer is the existence of industry and factories. Printing companies, textile factories and metal jobs produce a lot of noise pollution.
This caused inconvenience for residents living around the factory area and for the factory workers. Therefore, in the industry, workers must use earplugs to protect them from loud and noisy sounds, said the Earth Eclipse page.
