The dangers of noise pollution in the modern society

In our daily lives, there are all kinds of sounds, such as the sound of birds chirping, enchanting music and the mesmerising sound of running water. But there is another type of sound that is not so beautiful, the sound of noisy talking, the sound of the street and the sound of neighbours during renovation, etc. These sounds not only give us bad stimulation in our hearing, but also affect our mood and emotions, which is noise.

In recent years, urban noise pollution has become the third major urban nuisance after air and water pollution, increasingly affecting people’s quality of life and happiness index.

It has many harmful effects on the human body

Firstly, impact on hearing: according to the International Organisation for Standardisation (ISO), working in an environment with a noise level of 90 decibels for 30 years can result in an 18% chance of deafness.

Secondly, effects on sleep: Sleep can be disturbed by relatively light noise levels of 40 to 50 decibels. 40 decibels of sudden noise can wake up 10% of the population, while 70% of the population can be awakened by sudden noise levels of 60 decibels. Long-term environmental noise can interfere with sleep, causing insomnia, fatigue, memory loss and even neurasthenia, which can seriously affect normal life.

Meanwhile, effects on the cardiovascular system: Some studies have found that prolonged exposure to noise can raise blood pressure, especially in workers with a family history of hypertension.

Finally, emotional impact: Long-term exposure to noise can cause people to develop bad moods, and they are prone to tension, depression, fatigue and anger, which can affect not only the physical and mental health of individuals, but also interpersonal relationships.
