World Noise Day | Is your memory getting worse? It may be because of noise

On World Noise Day, Dongdongmiao will help you understand noise through five pictures.

01 Noise discrimination is subjective

Any sound that interferes with people's normal rest, study, work and other activities is considered noise.

02 How to measure the size of noise

A noise volume of 30 to 40 decibels is a relatively quiet environment, and more than 50 decibels will affect sleep and rest.
03 Noise pollution poses great risks

Long-term exposure to noise in daily life can cause hearing damage, and noise stimulation can also cause abnormal blood pressure and heart rhythm.

04 Noise can affect children’s intelligence

Long-term exposure to noise can affect children's attention and even lead to decreased intelligence and poor memory.

05 How to stay away from noise?

When decorating, you can choose double-glazed windows and wooden furniture. If that doesn’t work, you can wear noise-canceling headphones to rest.
