Influence of noise on health

Noise negatively affects people’s lives and even threatens their lives.

According to WHO, long-term exposure to noise above 55 dB can result in increased blood pressure or heart attack.

When the noise is more than 60 dB, auditory sense may not be impaired, but the cerebral nervous system is constantly impacted, causing damage to respiration, cardiovascular system and gastrointestinal tract.

Children who grow up in noisy environments are reported to have lower abilities of reading, verbal expression, and information memory than other children of the same age.
