- According to the U.S. Environmental Protection Agency, noises that exceed 80 decibels are detrimental to your health. Children are affected by noises above 60 decibels. The Decibel is the unit of measure for the intensity of sound waves and, in simple terms, any noise that dwarfs normal conversation between two people is most probably above 60 decibels.
- High-intensity sound waves cause unnecessary ripples in the ear canal, disturbing the fluid that aid communications between the ear and the brain. This disturbance destroys the tiny, very delicate, hair follicles that send signals to the brain whenever sounds enter the ear.
- Being exposed to noise pollution for ten consecutive years or more raises your chances of suffering from at least one cardiovascular disease later in life by 300%. About a decade back, scientists from the University of Gothenburg found out that high noise levels increase an individual’s pulse rates and cause constriction of blood vessels, thus making him/her vulnerable to heart attacks or high blood pressure. Being exposed to such noises for more than 8 hours a day could even be worse.
- The noises you ‘got used to’ can lead to serious psychological disorders and, sadly, you may not even realise it because it becomes a part of you. Research shows that too much noise makes people easily irritable, nervousness, irrational in decision making, and constant unease throughout the day.
- If you have ever lived in a noisy neighbourhood, you know how irregular sleep can get on a noisy night. The danger of not sleeping well at night is that your day gets boring, you get tired early, and you are forced to forego most energy-draining activities. You cannot, for example, be effective at the gym which increases cholesterol levels in your body. Poor sleeping patterns can also cause serious cardiovascular problems in the long run.
- If you have lost your hearing ability due to noise, it is imperative that you acquire hearing devices soonest possible. By so doing, you will be protecting your ear canals from further damage as well as getting your social vibe back. It is equally necessary for you to go slow on loud music, get noise-cancelling headphones when operating noisy machines such as the lawn mower, and to avoid staying near irritating noises for more than an hour.
